How Does Sound Masking Work?

Kristen Murphy | Acoustical Consulting | February 2nd, 2012

Have you ever increased the volume of your music or television program in an effort to “drown out” your noisy neighbors? Or have you noticed how difficult it is to hear a conversation while walking along a busy street? In both of these situations, the “masker” (your music/television, traffic) is changing the threshold at which the “signal” (noisy neighbors, conversation) is perceptible. In other words, some sounds are masking – or covering over – the other sounds. (more)

What is a Certified Technology Specialist (CTS)?

Tim Hamilton | Audio-Visual Design | January 18th, 2012

Most industries have some sort of accreditation process by which individuals and companies within that industry are recognized as being competent and knowledgeable within that field. For instance, architects are accredited by the American Institute of Architects (AIA), and acousticians are accredited by the National Council of Acoustical Consultants (NCAC). An individual that has these credentials has passed the necessary examinations, peer review, and required work hours to carry the credentials so that people who hire them can be assured they know what they are doing. So just what is a CTS? (more)

New ADA Assistive Listening System Requirements

Tim Hamilton | Audio-Visual Design | December 15th, 2011

Most people who work in the construction industry are aware of the Americans with Disabilities Act of 1990 (commonly referred to as the ADA) and the general impacts it has on how buildings are constructed. On September 15, 2010 the Department of Justice published a series of revised regulations. One section of these updates deals with requirements for ADA Assistive Listening Systems for persons who have hearing disabilities. It’s a subtle change, but a big deal. (more)

How Does Acoustical Absorption Work?

Melinda Miller | Acoustical Consulting | December 8th, 2011

Walk outside on a cold winter day just after the first big snowfall and you can hear the hush in the air. Everything sounds different because that hush in the air is the snow absorbing sound. Now, compare that to walking into a gym where the sound bounces around and lingers in the room. Also, have you wondered why some hotel rooms are “soundproof” and some seem to have walls that are paper thin? (more)

Student Job Shadows as an Acoustical Engineer

Administrator | K-12 Education | December 7th, 2011

Many high school students have never heard of the “acoustical engineering” field so when local student Jordan Van Buskirk  (a Senior at Western Michigan Christian High School) asked his teacher about jobs that have to do with acoustics, it was a first for the school. After being contacted by Joyce Workman, Director of Advancement at WMCHS, Acoustics By Design proposed a project centered around a problematic space for the school.  By working with an existing space, both Jordan and the school would benefit from the job shadow opportunity; Jordan was even able to get credit for a physics class by completing the project.  Jordan worked with Tim Koldenhoven of Acoustics By Design and identified the gymnasium as a space that needed improvements.  Not knowing what to expect, Jordan showed up on time and ready to learn.

Acoustical Solutions for Cafetoriums and Gymnatoria

Kenric Van Wyk | K-12 Education | December 1st, 2011

image of a cafetorium gymnatoria acoustical consultantMulti-use school facilities (such as “cafetoriums” – cafeterias that double as auditoriums) are popping up all over Michigan because they save space and save money. But many schools are finding that they are not well-suited to serve multiple purposes. So how can multi-use facilities be optimized for both utility (think cafeteria) and performance (think auditorium)? (more)

Training Tips for Church Tech Teams

Tim Hamilton | Worship | September 1st, 2011

image of church tech team training tipsI run sound at a local church about once a month. I used to spend time behind a mixing board several times a week, but these days it tends to be more time in front of a computer. Several recent discussions with the Music Director at the church got me pondering this question: What really makes a “good” mix? And the inevitable follow-up question is: How hard is it to train a church tech team volunteer so that they can get a “good” mix as the church sound board operator? Here’s my opinion… (more)

Is It Really Sound Proof? Mixed Use Developments

Tim Koldenhoven | Mixed Use | August 18th, 2011

Mixed use developments need to have the proper noise isolation partitions and the proper expectations for tenants. “I can hear their music and their phone ringing; I can even hear them repeat the order!” This comment came from a frustrated condo owner who lived above a sandwich shop in a mixed used condominium development. High density living often crashes with commercial spaces, and usually it is the residential owners that end up frustrated. (more)

Corporate Videoconference Guidelines & Recommendations – Part 2

Scott Storteboom | Corporate | August 3rd, 2011

Good communication can be difficult, especially over long distances. This is why we still get on airplanes and travel to meet face to face. Videoconferencing saves the travel costs, and it still gives us the face to face connection. But here’s the key: the videoconference environment itself is critical to ensuring communication success. Human ability (your eyes and ears) are much more forgiving than technology (cameras and microphones). For example, bad room lighting can automatically be mitigated by a change to your eye’s iris, but video cameras will capture an unusable or poor image.  Another example is room noise which can be filtered out by the brain but will be picked up by the microphone and ultimately decrease intelligibility.  So here is a list of common “weakest links” for corporate videoconferencing: (more)

Corporate Videoconference Guidelines & Recommendations – Part 1

Scott Storteboom | Corporate | July 20th, 2011

Teleconferencing requires hearing the voice, so it should follow that videoconferencing requires seeing the people, right? Not so much. Videoconferencing actually requires a finer level of detail – it requires seeing the eyes. Why? We communicate with our eyes. If you cannot clearly see the eyes of the communicator, then you might as well be on a teleconference. This is why web quality video has become unacceptable for many types of corporate communication.  Even more difficult are large spaces such as boardrooms or corporate auditoriums.  The size of these spaces alone presents a real challenge to the video conferencing system, making it ever more difficult to see the eyes. “So what?” you say. Well, the eventual reality is that without seeing the eyes, users will eventually avoid the technology altogether. (more)

A Tale of Two Halls

Administrator | Auditorium | July 7th, 2011

I recently attended concerts at two out-of-state prestigious university level music schools, and from a noise control point of view, the auditoria couldn’t have been more different. While the room acoustics of both halls were superb, the background noise level in one was quite distracting. (more)

IPTV –When it Makes Sense & Save Cents

Tim Hamilton | K-12 Education | June 23rd, 2011

One of the transitions that we are watching closely in the audio-visual Industry is the evolution of audio and video delivery over networks instead of through dedicated distribution systems. In the consumer world you may have noticed that some TV networks are starting to stream things like major sporting events from their websites, or you may have signed up for a service like Netflix or Hulu Plus to stream movies to your TV. These are examples of TV delivered over the Internet – commonly called IPTV. (more)

Toilet Noise Mitigation

Administrator | Hospitality | June 2nd, 2011

The other day at a popular chain restaurant, I dropped by the restroom before a long ride home. I’ve heard some loud toilet flushes in my day, and this one was right up there with the loudest of them. While it caught my attention, it didn’t make me jump too high out of surprise. However, when I saw a young girl coming out of the neighboring stall, she had a look of shock on her face. She said, “That SCARED me!” Not something I would think most businesses want to do to their customers. (more)

The National Council of Acoustical Consultants & the American Institute of Architects

Tom Thelen | Sustainable | May 11th, 2011

The National Council of Acoustical Consultants (NCAC) is the only North American organization fully devoted to certifying the credentials of acoustical consultants. Kenric Van Wyk, President of Acoustics By Design, was elected to the NCAC Board of Directors in 2006.  He has served as the Vice President of Finance, and was recently elected as the Vice President of Marketing and Communications. To join the NCAC, acoustical engineering firms have to be completely independent with no ties to any product manufacturers or distributors. This ensures that each firm provides objective recommendations that are free from bias. Since 1962, the NCAC has supported the acoustical profession through:

  • recognizing expert Acoustical Consultants and Engineers.
  • promoting opportunities for peer interaction.
  • providing a reference tool for the public to learn more about the profession and to find a consultant matched to their needs. (more)
