Audio Visual Glossary
Written By: Kate Couch and Tony Sprando
Whether you’re new to the audio-visual world or an old pro, a glossary of words to help you understand what we’re referencing in our articles and communications with you is a helpful tool. Below is some common audio-visual lingo with its proper definitions. It’s broken up into different categories, video, audio, av it, lighting, and general.
ANSI – American National Standards Institute. Where does it apply? ANSI, lumens in relation to a projector the brightness of a projector.
DLP – Digital Light Processing(c) by Texas Instruments. A projection system that has technology based on the Digital Micromirror Device (DMD). It uses thousands of microscopic mirrors on a chip focused through an optical system to display images on the screen.
Front screen projection – a system that employs a light-reflecting screen for use when the image will be projected from a source in front of the screen.
LCD – Liquid Crystal Display.
LCoS – Liquid Crystal on Silicon
LED – Light Emitting Diode.
Viewing angle – the viewing angle determines how far off the axis (screen centerline) a viewer can still sit and still see a quality image. This is no greater than 45 degrees off the projection axis.
Zoom lens – lenses that allow the operator to adjust the focal length for sizing or distance.
Lumen – a measure of the light quantity emitted from a constant light source across one square meter.
Matte white screen – evenly disperses light 240 degrees uniformly, both horizontally and vertically, creating a wide viewing cone and wide viewing angle. Below is a common site for buying screens
Codec– There are two kinds, soft codec, which would be google hang out, web x, or zoom they live on my butt or are “butt-based.” Conference or hardware codec would be a conference call hosted by the person indicating the call, poli-cons.
native resolution – The number of rows of horizontal and vertical pixels that create the picture. The native resolution describes the actual resolution of the imaging device and not the resolution of the delivery signal.
Nit – the metric unit for the screen, or surface brightness.
Pixel – an acronym for picture element. The small element used to build a digital image.
Ratio – the comparison of two quantities. Aspect ratio 16:10 16:9 4:3
Rear screen projection – a presentation system in which the image is projected through a translucent screen toward the audience; projecting an image through a translucent screen material for viewing from the opposite side, as opposed to front projection.
Resolution – 1. the amount of detail in an image. 2. the number of picture elements (pixels) in a display.
Scaler – feature in a display device that changes the size of an image without changing its shape. Scaling may be required when the image size does not fit the display device.
Throw distance – the length of the projection beam necessary for a particular projector to produce an image of a specified size. It’s common to use a throw distance calculator like the one linked below https://www.projectorcentral.com/projection-calculator-pro.cfm
Mixer – a device for blending multiple audio sources.
Bi-directional polar pattern – the shape of the region where some microphones will be most sensitive to sound from the front and rear while rejecting sound from the top, bottom, and sides.
Boundary microphone – a microphone that relies on reflected sound from a surrounding surface.
Cardioid – a heart-shaped region where some microphones will be most sensitive to sound predominately from the front of the microphone diaphragm and reject sound coming from the sides and rear.
SPL– Sound pressure level. Sound pressure or acoustic pressure is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave. In the air, sound pressure can be measured using a microphone, and in water with a hydrophone. The SI unit of sound pressure is the pascal. See more here, https://www.youtube.com/watch?v=OSRwM2yy3co
Delay– an audio signal processing device or circuit used to retard the speed of transmission on one or more audio signals or frequencies.
Dynamic microphone – a pressure-sensitive microphone of moving coil design that transduces sound into electricity using electromagnetic principles. Linked is the Shure SM58 one of the most popular dynamic microphones on the market today. Shop
Echo cancellation – a means of eliminating echo from an audio path. Learn more from this website below https://wiki.analog.com/resources/tools-software/sigmastudio/toolbox/adialgorithms/aec
Feedback – 1. unwanted noise caused by the loop of an audio system’s output back to its input. 2. in a control system, data supplied to give an indication of status, i.e., on or off.
Gain – 1. electronic signal amplification. 2. the ability of a projection screen to concentrate light. + gain b4 feedback
Lavalier – a small microphone designed to be worn either around the neck or clipped to apparel.
Midrange – loudspeakers that reproduce midrange frequencies, typically 300 Hz – 8,000 Hz. high mid and low
Mixer – a device for blending multiple audio sources.
Monophonic – uses input from all microphones and relays them from the electronic control system to the loudspeakers using a single path or channel.
Notch filter – “notches out,” or eliminates, a specific band of frequencies.
Omnidirectional – describes the shape of the area for microphones that have equal sensitivity to sound from nearly all directions. Like the SM58 as well as a directional microphone
Phantom power – a direct current (DC) power source available in various voltages. Commonly found on audio mixers and interfaces required by most condenser microphones.
Point-source – a sound system that has a central location for the loudspeaker(s), mounted high above, intended to cover a large area; typical of a performance venue or a large house of worship.
Shotgun microphone – a long, cylindrical, highly sensitive, unidirectional microphone used to pick up sound from a great distance.
Speakon(c) – specialized connector used to hook up speakers without causing a short circuit; allows connection of speaker while working, or hot.
Array speakers – Or line array, A-line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near-line source of the sound. A vertical line array displays a normally wide horizontal pattern useful for supplying sound to the majority of a concert audience. They are usually curved and have stacks of rectangular-shaped speakers.
Polar pattern – (or pickup pattern); the shape of the area that a microphone will be most sensitive to sound.
Radiofrequency (RF) – generally refers to signals such as radio and TV broadcast signals, or radiofrequency control signals; the range of frequencies used for electrical transmission.
Radiofrequency interference (RFI) – the tendency of a radio transmission to interfere with other electronic signals. Radiofrequency energy is radiated by all electrical equipment – when it is a strong enough signal it becomes interference in audio systems.
Subwoofers – loudspeakers that reproduce lower frequencies, typically 20 Hz – 200 Hz.
Super-Cardioid Polar Pattern – the exaggerated heart-shape of the area that a highly directional microphone is most sensitive to sound.
Boundary Microphone– placed on a table to pick up sound. Used in boardrooms and other environments where a number of talkers must be “picked up” and where the microphone needs to remain unobtrusive. It uses the table to increase the pick-up. “Preferable wood sources”
TRS – Tip, Ring, Sleeve – a three-conductor design of a phone connector that can be terminated as balanced or unbalanced.
TS – Tip, Sleeve – a two-conductor design of a phone connector used for an unbalanced circuit.
Unbalanced circuit – transmits the audio signal on a single conductor that is referenced to the ground. +balence circuit
Woofers – loudspeakers that have low frequencies, typically 20 Hz – 200 Hz.
Footcandle – abbreviated as Ftc, it is an English unit of measure expressing the intensity of light illuminating an object. The illumination from one candle falling on a surface of 1 square foot at a distance of 1 foot.
Lux – a contraction of the words luminance and flux; metric version of footcandle.
Diffusion – The scattering or random redistribution of a sound wave from a surface. It occurs when surfaces are at least as long as the sound wavelengths, but not more than four times as long.
Ambient noise – a sound that is extraneous to the intended, desired, intentional, audio; background noise.
Direct sound – also known as near-field, is a sound that is not colored by room reflections.
Distributed sound – a sound system in multiple loudspeakers separated by distance and typically operates in a lower sound pressure level than a high-pressure system. The loudspeakers are most often suspended over the heads of the listeners.
Distribution amplifier – an active device used to split one input into multiple outputs while keeping each output isolated, and the signal level constant.
Early reflected sound – created by sound waves which are reflected (bounced) off surfaces between the source and the listener. The sound waves arrive at the listener’s ear closely on the heels of the direct sound wave
Fundamental frequency – the lowest frequency in a harmonic series; known as “pure tone.” White noise- white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. Used for sleep and in healthcare.
Pink noise– Pink noise or ¹⁄f noise is a signal or process with a frequency spectrum such that the power spectral density is inversely proportional to the frequency of the signal. In pink noise, each octave interval carries an equal amount of noise energy. Pink noise is one of the most common signals in biological systems.
Brown noise– In science, Brownian noise, also known as Brown noise or red noise, is the kind of signal noise produced by Brownian motion, hence its alternative name of random walk noise.
Below is a link that explains the science of white pink and brown noise. https://www.soundofsleep.com/white-pink-brown-noise-whats-difference/
Near-field – A sound that has not been colored by room reflections. This is also known as the direct sound.
Reflection – light or sound energy that has been redirected by a surface.
WLAN – Wireless Local Area Network; a network that shares information by radio frequency (RF).
Twisted pair – any number of wires that are paired together and twisted around each other; can be shielded or unshielded.
Cats are sets of cables with each one getting more durable to read about the difference between all of them see this article. https://www.loxone.com/enus/blog/cat7-cable/
Category 5 (Cat 5) – the designation for 100-ohm unshielded twisted-pair cables and associated connecting hardware whose characteristics are specified for data transmission up to 100 Mb/s. (Part of the EIA/TIA 568A standard.)
Category 5e (Cat 5e) – an enhanced version of the Cat-5 cable standard that adds specifications for far-end crosstalk. (Part of the EIA/TIA 568A standard.)
Category 6 (Cat 6) – cable standard for Gigabit Ethernet and other interconnect that is backward compatible with Category 5 cable, Cat-5e, and Cat-3. Cat-6 features more stringent specifications for crosstalk and system noise. (Part of the EIA/TIA 568A standard.)
Category 7(Cat7) –CAT 7 cable, whilst being the more expensive option, is also considered the most durable, and has a longer lifespan than CAT 5 and CAT 6, improving its overall return on investment, and is the best choice for wiring with the future in mind.
Category 8- Category 8, or just Cat8, is the latest IEEE standard in copper Ethernet cable. It represents a significant leap in data transfer speed over the earlier Cat7 and Cat6a cables. It uses standard RJ45 connectors and is backward compatible with previous standards.
Ethernet – a set of network cabling and network access protocol standards for bus topology computer networks invented by Xerox but now controlled by the 802.3 subcommittees of the IEEE.
Fiber optic – a technology that uses glass or plastic threads or wires to transmit information. Now applies to so much more than just data transmission goes through everything that has to do with av and control and it is “inwall” rated because glass is not “inductive” “glass is an insulator
LAN (local area network) – a computer network limited to the immediate area, usually the same building or floor of a building. The Internet is a globally-connected network of computers that enables people to share information and communicate with each other. An intranet, on the other hand, is a local or restricted network that enables people to store, organize, and share information within an organization.
Cable shielding– a physical layer in some cables used to protect signals and sometimes used as a return path for current. Three basic types foil, braid, and combination.
Equipment rack – a centralized housing unit that protects and organizes electronic equipment.
Matrix switcher – an electronic device with multiple inputs and outputs, the matrix allows any input to be connected to any one, several, or all of the outputs. One audio one video
Rack unit (RU) – unit of measure of the vertical space in a rack. One RU equals 1.75 inches (44.5 mm).
Streaming video and audio – sequence of “moving images” or “sounds” sent in a continuous, compressed stream over the Internet and displayed by the viewer as they arrive. With streaming video or audio, a web user does not have to wait to download a large file before seeing the video or hearing the sound.
BTU-Measurement of heat. The British thermal unit is a unit of heat; it is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units. Heat is now known to be equivalent to energy.

When cleaning out spaces and redesigning spaces how to decided what AV systems to reuse and what ones need new life.
Written By: Kate Couch and Tony Sprando
With spring just around the corner and the days becoming more consistently in the 50s it’s time for most people to do their annual spring cleaning. Whether for your home and personal use or for commercial and business use a good spring cleaning is always a good idea. Getting rid of old things and deciding to get new things and redesign them brings up some questions about AV. Many people will frequently come across a decision to reuse the AV or electrical systems that they have in place or whether they need to get a new one.
The idea to reuse an AV system is normally the client’s idea, however, the AV installer and the AV designer will all have their own input and ideas about this. When working with a budget it’s always a good idea to try to pinch pennies when you can. But pretending something is in good working condition when it’s not it’s just going to cost you more money down the road. The designer and the installer both have this in the back of their mind ( though the designer is going to try to reuse as much as possible where the installer will not spend as much time on that typically) and the nice thing about AV systems is unlike, say, an air conditioning unit, you don’t have to get rid of the entire thing essentially, you can reuse bits and pieces if they’re still good. You might need new screens or new monitors, but your projector is just fine. You might need new sound equipment, but the soundproofing solution is just fine. It’s important that the AV designer and the AV installer work together to reuse as much as possible while not being overly hopeful about the equipment which could cause problems later on.
Our approach at AV Bend is that every job has one thing in common… power. You need power and it needs to be clean. This means clean, with no buzz and a dedicated ground must be established for the AV system. I was asked to do a quote for a church and everything looked straightforward until I ask to look at the electrical panel. They told me “ oh this caught fire once” and it sure looked that way, though it had been repaired. The repair did not include any upgrades or accommodations for audiovisual. On top of that everything shared a common ground. This once easy fix is no longer acceptable. I had to tell them, then I sourced an electrician to get the panel and wiring done the way I needed before I could prepare an AV design and bill of materials list. This cost the customer thousands of dollars before any AV gear was purchased, but in this case, we had to rip out the old so we could build onto a brand new electrical foundation. This luckily doesn’t happen all that often but If I had just put in the system with what they had before it could have been a fire danger or broken the equipment I put in; which would have cost them more in the long run.
The bottom line is that when working with an AV designer, installer, and possibly an electrician deciding what AV system to reuse make sure you have clean power. In addition to clean power a system that’s up-to-date and going to be working with your needs over at least the next couple of years. This way you will avoid the dangers of an outdated or not up to code system.

Like many other people, I enjoy listening to (somewhat loud) music while I work. I can zone out of the background noise and get to the important stuff. I have noticed something recently that it is a shared interest, as I also hear other’s loud music while I work. Naturally, this poses a bit of a noise problem, luckily it can be easier to fix than it appears. With most people working in different environments these days little noses add up and can become unbearable. With some quick identification and problem solving you can fix your noise issue before the next work week.
Music has been proven to help improve the efficacy of work. In a study done by, Tayyari, Fariborz, and James L. Smith. “Effect of Music on Performance in Human-Computer Interface.” “It was found that, while the music did not disturb the overall accuracy of the task output, it increased the subjects’ speed in data processing and overall productivity. The subjects showed a favorable attitude toward music being introduced at workstations.” Music can be help keeping us focused but a hindrance when others do it. The solution might seem to stop listing to loud music. This is not always the case. What people forget is our homes are filled with lots of sounds every day and when they get above a certain DB we notice them and they become disturbing.
No offense to my neighbors but their HVAC unit is loud as all get out. Or the sounds of my children running up and down the halls, traffic, and the occasional annoying bird. This can be the difference between getting stuff done and not being able to get in the zone. So now that we have identified a noise issue where the solution can’t be stoping the root of the noise we have a few options.
Door sealing kit.
A door sealing kit is going to be the best option when reducing noise in a small room from outside contributors. You can also do this on the windows as well. This will reduce the amount of noise from the outside getting inside and from the inside getting outside. Contrary to a typical acoustical treatment plan where you might have noise reduction materials on the inside; the objective of this acoustical treatment plan is to prevent small, but loud noises, from outside from getting on the inside.
There’s a little bit of science to this as well. Which has to do with DB. The DB is essentially how loud a noise is. Below is pictured a chart of the common DB of household noise. Figuring out the DB of certain things around your home will help you when making a goal for where you want the noise level to be. The average household with some or no conversation is between 40-60 DB so if you find yourself disturbed by noise a good goal is to get your room back to 60<. Like we mentioned earlier this can most likely be achieved with a door and window sealing kit.

Working at home the noise of neighbors, family members, and roommates can sometimes be disruptive. But when the problems identified you’ll find it with the most basic noise issues there is a basic noise solution.

Solving problems of outdoor electronic screens and touch screens.
Written By: Kate Couch with collaboration with Tony Sprando
Outdoor TVs, touch screens, and monitors are nothing new. They’ve been used for decades to display things like game scores, travel plans, city maps, advertisements, bus and train routes, and general outdoor entertainment. These monitors and screens are rated for outdoor weather. Though these screens aren’t super common in areas that get freezing temperatures (like the Pacific Northwest.) They can still be found in these areas and commonly are necessary. Football and other sporting events have all kinds of outdoor screens: maps for the stadium, scoreboards, and advertisements. Stadiums are one of the most common places that you will see outdoor monitors and touch screens.
Because of the temperature problem and the harsh weather conditions in addition to the usage of hundreds to thousands of people interacting with the screens, there can be a huge problem when it comes to installing and making sure these screens are being serviced properly and kept in good condition.
The solution to these problems is an outdoor touch screen enclosure. This concept is known by many names, “touch screen monitor protector” or “outdoor touch screen monitor cabinet.” These enclosures are made from strong materials that can withstand harsh weather conditions and protect the screens and monitors. They’re made from weatherproofing materials in addition to the weatherproofing materials and ratings that the monitors and screens are made out of. This extra layer of protection can prevent ice, wind, heat, and snow from permanently damaging the monitor.
These enclosures and protections are often times removable since they can be somewhat disturbing to the original intended purpose of the screen. So by these protections being put over
them when the screen is not in use, it extends the life of the monitor. When installing an outdoor touch screen or monitor system it’s important to consider that a client could vastly benefit from having one of these enclosures whether permanent or removable. Ones that are more permanent tend to look like a pergola or a tent design for the main intent of the monitor or touch screen.
There is some debate and controversy on whether you actually need an enclosure for your outdoor screen TV or monitor. This really depends on the weather conditions in your area. In places like Southern California, it is very rare to see an enclosure since their weather is so consistent. However, you will see things like sun shades to protect weathering from the sun. The question should not be “do I need an enclosure for my outdoor screen” and it should be “what weather is going to impact my outdoor screen?” By focusing on the problem from that angle you’ll be able to easily, efficiently, and cost-effectively solve the problem so your outdoor screen to have the longest best functioning life.

Things to keep in mind when establishing the reputation of your company.
Written By: Tony Sprando and Kate Couch
Most people fall under the assumption that reputation can only be built over time. The mom-and-pop shop that’s been around since the 50s doing things the good old-fashioned way. Or the tried-and-true Google ratings. Though these things can be important for a business to have they are not everything. It seems like everyone is so focused on the “eye candy.” What can they do to instantly catch people’s attention? A flashy website, cool photos, merchandise, or a 5-star review on Google. But the problem is with the focus placed on the things that may satisfy the instant gratification, the hard-working, job well-done, reputation can fall through the cracks. When browsing the internet the internet, cool, stock images may catch the eye but don’t really replace or represent a good reputation
This idea of judging a book by its cover has been around for eons. When looking for a place to eat, when looking for a new book to read, even when looking for a spouse we tend to go with things that we notice first, things that catch our eye. The problem with these things is that they tend to not last or properly represent their value. I have read plenty of books with gorgeous covers and even better pages, I have also chosen based of the flashy cover and they ended up being awful. There is precedent importance on the little things, though not as shiny they hold a much deeper hidden weight.
What makes a good company good?
When thinking about what makes good company things like excellent customer service, quality products, timely delivery and installation, and pleasant employees all come to mind. These things often drive the inspiration for a five-star rating on Google. Novice business owners frequently focus on getting the rating rather than building the foundation for these grounds. If you want good reviews on the internet look at where your customers are most frequently involved with your company. How is your customer service? If you’re providing a service like AV are you executing their ideas and solving their problems? These things will build an excellent reputation for your brand.
What is AV Bend’s formula?
Every job comes down to the person leaving it from start to finish. Did the customer have a good experience on the phone? Did the customer’s ideas get executed properly? Did the customer understand what was happening and what technology or systems were being integrated into their business or home? These are the questions that AV Bend asks themselves while on the job to make sure that the job, start to finish is done properly and the customer feels satisfied. These are the grounds for a good reputation, that any business AV or not can follow.
An AV Bend Story
Most of our AV jobs are start to finish but every once in a while we’ll have particularly more involvement with the customer involving higher-level AV techs. In one case, a customer needed more training (learning how to operate the things being installed) on their project than what was in our normal scope of work, so they felt frustrated. This is understandable and luckily doesn’t happen too frequently. There’s always a way to make things right. We made a point to take the customer out to lunch and listen. Listening is the best tool we have. This made them feel important and we then proceeded to buy the entire onsite team dinner and provide an in-depth training session. This wrapped up the job nicely, informed all of our employees, and made a customer feel listened to. All these things were important to making the project properly executed.
Listening in any area of life is extraordinarily important and gives me the difference between a good reputation and a bad one.

“Age appears to be best in four things, – old wood best to burn, old wine to drink, old friends to trust, and old authors to read.” – Alonso Of Aragon
Age is something we have been redefining for many years as a human race. In the 40s children were seen and not heard, today children are brought to work and meetings and expected to be kept entertained by their 8×12 screens that they are constantly glued to. When I was a teenager I knew all the latest tech but now I’m (slowly) slipping behind. My mother-in-law though, not tech-savvy, picks up things as fast as ever. She is I presume sharper than most people her age. My beautiful wife does not keep up with technology and prefers to be outside. Due to this, she has much better eyesight than I do, however, I have better hearing. It’s a two-way street of what we choose to invest our time in.
As we get older and more mature the brain changes drastically. Most people are aware of this, it’s called cognitive decline. It’s a sad thing to go through and to see others go through. When things that are so drastically important to us like, hearing, seeing, our ability to learn, and our memory slowly worsen with every year. It can be hard as a parent, friend, loved one, or business owner to know how to properly help people experiencing this. Age Is something not a lot of people take into account when doing custom work for clients. It’s something that’s overlooked but extraordinarily important.
It’s important to understand at what ages different needs need to be met. As someone reaches the age of 60 they have a hard time keeping things organized, remembering things, and hearing and seeing things. If you have someone over the age of 60 for a client you want to make sure that you’re catering to these needs. For example, in audiovisual, if you have an older client it is important that you are making sure that the speakers in an in-home speaker system are arranged properly so they can hear it. Checking that older clients technology you might be installing is easy for them to use, and that they understand what you’re putting in their home is another important thing you can consider. Solving organization problems and making sure that your clients know how to properly use what you’re installing and understand its function. Just because somebody comes to you with a problem, doesn’t necessarily mean that they understand the solution.
When it comes to this in Audio Visual it’s important to take into account age with any client you have. For example, if you are installing soundproof panels into a nursery something that is professional, business style, and chic probably wouldn’t cater to that age or audience. You need to take into account the problems that you are solving will also considering the age of the client installing something that is more child-proof and childlike is more likely to leave the customer satisfied.
If you are installing a meeting room for a business whose employees are young and tech-savvy you can keep that in mind when integrating the latest and smartest technology. Integrating a necessary thing like a zoom room into a company that has older employees that don’t know how to use technology but are going to rely on Zoom calls. You can use technology that’s more straightforward organized and easy to use. It’s very easy to cater to a client’s age if you just consider the problem that they need to solve and how their age affects that problem.
Defining the word that has had so many meanings over the past one hundred years.
Written By: Kate Couch
“Okay, Einstien.” “That was smart!” “You’re baby is so smart.”These are all common sayings we’ve heard that center around the idea of smart or intelligence. But what is smart? As we progressed further into the 21st century, technology seems to be out doing itself every day. The stock market is skyrocketing, the way we interact with each other and do business has changed completely, and the internet seems to rule our lives. So when we hear the word “smart” how has its meaning changed? Most of you have a smartphone in your pocket, many teachers have smart boards (a technology integrated touch screen whiteboard with a proprietary pen with software) and our kitchen is filled with “smart” appliances.
How this applies today
Today the word smart can be used to reference technology, specifically artificial intelligence technology. AI was a word that scared a lot of people a decade or two ago. Now it’s nearly unavoidable. With the word smart directly correlating to an item having some sort of artificial intelligence, smart devices, and AI devices, are in more places than we realize. The demonizing of artificial intelligence through science fiction movies is what caused a lot of pandemonium when it came to the idea of your technology being “smart.” The truth is, there’s a lot of benefits to having smart technology. We know it’s constantly making our lives easier and more efficient. Especially right now, as we heavily rely on technology to carry our schools and jobs.
Where does AV come in?
Audio and visual technology and setup have become extremely important during the pandemic; especially relating to zoom rooms. Audio Visual Bend does Zoom rooms for clients since the pandemic. A Zoom room is essentially a room with an acoustical treatment plan, cameras, microphones, and a speaker setup for Zoom meetings. It’s an essential function to help schools and businesses have effective and efficient meetings. Having properly set up cameras, speakers, and microphone systems make the stress of having a zoom meeting melt away. In addition to this, the soundproofing and acoustical treatment plan will diminish the possibility disrupting of others and minimize others disrupting you.
Audio Visual and smart technology doesn’t end with Zoom meetings though. Before the pandemic audiovisual mixed with smart technology often looked like integrating smart devices and appliances. Often customers would want in-home speaker systems and automatic lighting that can be adjusted with simpler panels or even from their phones. Customers often strived for a result that was less autonomous.
Where is it going?
Audio-visual definitely has some changes coming in the future with the way technology is going. 10 years ago audiovisual was more corporate-based and for wealthier clients. But as technology progresses audio-visual becomes more affordable. Audio Visual Bend predicts that more of our customers want to be integrating systems into their homes like speakers, cameras, projectors, and acoustical treatments over the next few years. It will start to look more like an in-home service industry model, rather than a one-time installation of a product or solving a problem. It’ll be something that’s ongoing integrating new technology into homes and corporate offices.
Smart is definitely a peculiar word with lots of meaning. But with new waves of technology coming out all the time and audio and visual being thrown into an entirely new pool of opportunities the word “smart” really has developed its own new meaning.
Earlier this year I found myself in predicament. Late at night, I would like to lift weights, work out, and do a bit of overtime, all while blasting music to keep the energy up. This quickly caused a problem as the rest of the household didn’t appreciate the concerts I held in the middle of the night, not to mention the neighbors that didn’t want that either. So I had a couple of options, I could go to a 24-hour gym (which at the time were open but little did I know that would have been a temporary fix) Or I could design my own workspace that would reduce the sound by drafting an acoustical treatment plan.
Avoiding the sweaty gyms and having the freedom of being in my own home while having the option to have my music through a speaker was a no brainer choice. So my wife and I designed an acoustical plan.
What is an acoustical treatment plan?
In short, it is a design that will solve your problems and make the room better for recording and listening to audio. When making an acoustical treatment plan you need to decide what your main problems are and how much coverage you need. Most people need between 25% and 75% coverage. This is only for the walls and ceiling. Most people forget when treating a room that the ceiling is just as important when it comes to treating a room as the walls are. So when buying or collecting materials make sure to pick up some for the ceiling too.
How do you go about it?
When I was making mine I decided to use scraps from a previous project. I had odd shapes of sound silencer material, which was perfect for the outcome but the shapes would be a creative challenge. My wife and I spent time maneuvering the pieces into intricate designs that would get the job done while still being aesthetically pleasing. This process saved us money and kept our room design unique, compared to the typical soundproofing methods.
Find a store that sells soundproofing materials then draw out a design for your room while placement is important that doesn’t mean you can’t make pieces that look good in the right places. The sound silencer is a unique product, from an initial look it looks like styrofoam but it is actually tiny engineered beads molded together, which is both functional and pleasing to the eyes.
After implementing this plan the sound was reduced drastically. I now have a place where I can do work and be as loud as needed while others can sleep peacefully just a wall away. My wife and I had a great time working on this together it was a good problem-solving experience and gave us some extra time together. Most people think that acoustical treatments are eyesores…and they wouldn’t be completely wrong. It’s great that we were able to come up with something that worked for our space and looked cool.
Putting soundproof panels behind canvas pictures, or cutting them into unique designs are simple ways you can make acoustical treatments a designing choice instead of a functional eyesore. This project was cost-effective, made use of old material, and solved our main problem.
