Gymnasium Acoustics | The Multi-Use Problem
Gymnasiums often end up being multi-use spaces. Of course, they are used for competitive sporting events, for team practice, recreation, and for Phys Ed classes. But they are also used for school addresses, commencement ceremonies, band and choir concerts, and more. Those with stages are used for musicals, plays, and speaking events. I have been asked to help mitigate acoustical problems more often in gymnasiums than in any other type of school space; possibly more often than in any other type of space, period. And there are almost always two complaints that I hear… (more)
Why Your Conference Room Technology May Soon Be Obsolete: Part II
As the VGA connector continues its rapid transition towards obsolescence (referred to in Part I of this post) many people simply assume that using adapters (such as HDMI to VGA) will solve the digital-to-analog connectivity problem. While this may work in the short term, it ignores the looming problem of DRM (Digital Rights Management), a way of encrypting new media to protect against copyright infringement. DRM uses something called HDCP (High Bandwidth Digital Content Protection) to control which devices are allowed to receive the video signal. So how will you know if you’re using digitally protected content? Well, for starters, your adapter will just stop working. (more)
What Do Acoustical Consultants Actually Do?
As an acoustical consultant, I often have trouble answering the “what do you do?” question. The basic answer is quite easy, but unless the person asking the question is an architect, performing artist, or involved in music, they often don’t have a clue what the job entails. I ran into this problem the first time I met my mother-in-law. She genuinely wanted to know and understand what I did for a living, but not being involved in the performing arts or technical sciences made it difficult, and I had a hard time communicating my trade. So what exactly does an acoustical consultant do, anyway? (more)
Why Techies Buy Audio-Video Gear Online
My church recently decided to upgrade from our old analog mixing board to a brand new digital mixing console. The interesting part of this process was that they did not buy it through a local AV contractor. They purchased the sound board online through a company that specializes in phone and internet box sales. This got me thinking about the trend over the past few years in which more and more Audio Visual end-users purchase equipment from online sources instead of the local dealer or shop. Is this a good thing or a bad thing? And why is this becoming the norm? (more)
The Speaker Shootout at High Noon
Question: How do you assure your client that they are getting the best possible speakers for their Auditorium or Fine Arts Center? Answer: You hold a “speaker shootout”. Recently one of our clients was in this exact situation, so we did just that. We invited several manufacturers of line array speakers to show up, all on the same day, so we could let our client hear the differences in sound quality back and forth in the exact same auditorium they would be installed in. Three different manufacturers arrived, speakers in tow, to hang their line arrays for the shootout. As the client’s AV Consulting Firm, we were there to moderate the shootout and ensure that each manufacturer got a fair shake (clean signal, volume levels, sound power levels, and so on). And then we began. The client had arranged for a group of about 20 listeners and key decision makers to join us for the shootout as a virtual “jury” to help decide which speakers to purchase. May the best speakers win! (more)
Why Your Conference Room Technology May Soon Be Obsolete
You can’t get away from the digital age. It seems like digital technology is everywhere. As Audio-Video designers, the march towards all things digital is having an impact on display technologies as well. Meanwhile, flying under the radar, there is a subtle shift happening in how the average person shows information from a computer onto a projector or display. (more)
If It Sounds Like Noise to You, It May Be “Esion”
Fundamentally, sound is “that which we hear”. What we hear at any given time can greatly influence us. We use sound to communicate, to express warning, fear, pleasure and excitement. Some sounds can relax us and help us fall asleep, while other sounds can distract us and make it more difficult to perform simple tasks. Different sounds can be soothing and pleasing or annoying and irritating. Accordingly, determining “What is sound?” and “What is noise?” can become a highly subjective task. As engineers and scientists, it’s our job to generate generalized models that have a high level of correlation to humans (or to specific populations). (more)
2009 AIA Grand Valley Honor Award Winners
This past Saturday night we attended the 2009 AIA Grand Valley Honor Awards program at the Urban Institute of Contemporary Arts (UICA) in downtown Grand Rapids. As a Professional Affiliate Member of the AIA, our firm serves as consultants to architects. Although we are not eligible to receive an award, we look forward to the chance to support our friends and celebrate their accomplishments in architecture over the last year. In addition, Acoustics By Design was pleased to be the acoustical and audio/video design consultants for six of the nominated projects! The real surprise of the night was that the independent judges panel, made up of three distinguished architects from Iowa, declined to give out awards in several categories.

Doggy Daycare Noise Control – Acoustic Roadblocks
Are you planning to open a veterinary hospital? A doggy daycare? A kennel? A private dog park? If so, then make sure that you consider the noise issues ahead of time (i.e., the barking)! Although these types of projects only account for a small portion of our work at Acoustics By Design, we end up assisting with noise control for at least a couple of these animal facilities every year. And when it comes to building the perfect doggy daycare or kennel, there is always a common list of acoustic roadblocks. (more)
