Optimizing Church Sanctuary Acoustics for Congregational Singing
I recently received a call from a pastor asking how to enhance their congregational singing. The church had recently inherited a new building, and the pastor was concerned that the congregational singing was just not “what it should be”. The band was great, and they rocked the place out. But the congregation was feeling a bit overwhelmed and “lost in the crowd”. (more)
How People Discover Acoustical Engineering
I admit that I like working in a niche field. I especially like the reactions of people who ask me what I do for a living and have never heard of an acoustics engineer. They find it amazing that someone does this type of work, or they start asking questions or making comments about some experience they have had with (usually poor) acoustics. Recently, on my way to an acoustics conference, I crossed the border at Detroit’s Ambassador Bridge, which is the busiest US-Canadian crossing… (more)
Noise Isolation for Church Cry-Rooms
Most parents will tell you that they just wish they could understand why their baby is crying. As cute as babies are, the reality is they can be immensely distracting during church worship services. So what can you do about it? (more)
Electronic vs. HVAC Sound Masking
Occasionally clients ask about using HVAC system noise as a sound masking system. While dual use of the HVAC system would save money and be more sustainable, most ventilation systems cannot be relied upon to produce a constant level of background noise with a desirable spectrum of sound. With the widespread use of variable air volume systems, the inconsistent air flow volume produces varying levels of background sound. At best, it would provide a hit-or-miss situation: sometimes it would be an effective masking system, assuming the spectrum doesn’t annoy the occupants, but most of the time it would not. Furthermore, the sound spectrum cannot be changed; you get what it is, which may not be what the occupants need. (more)
American Disabilities Act to Accommodate Hearing-Impaired Students
The phrase “Equal Access” might not be very exciting, but it represents what many perceive to be a fundamental right of modern society. Every building built in the last 20 years has personified “Equal Access” by including doors wide enough for a wheelchair, elevator signage with braille lettering for blind persons, and auditoriums with hearing assist systems for those hard of hearing. While children in wheelchairs have “Equal Access to Learning” in school classrooms today, those with hearing difficulties are denied the same opportunity. In many classrooms, the students cannot hear the teacher due to the loud mechanical system or the nearby airport. And, if they can’t hear, they can’t learn. But that’s all about to change. (more)
Not All Acoustical Surfaces Are Created Equal
The orchestra that I play in used to perform at local public schools. The high school auditoria that we regularly used were so-so for acoustics, but we learned to appreciate them when a scheduling conflict bumped us to a junior high school for one concert. This auditorium ceiling was treated with a spray-on absorbing material that made it feel like we were playing into a sonic black hole. After we finished, it sounded like twenty people were clapping, which I hope there were more…maybe not if they couldn’t hear us. (more)
In an effort to be inspired, I happen to be writing this blog from my hotel room so it seems perfectly fitting that I write today about Hotel Room Noise Isolation. This is a bit of a tricky topic because there is a whole range of expectations that exist between the one or two star roadside motel and the 4-star hotel that I am currently staying in courtesy of our firm’s thriftiness and a sweet deal from hotwire.com. Of course, nobody checks into a hotel expecting to get a poor night of sleep regardless of the quality or star rating of the establishment.

Naturally Ventilated Buildings and Loud Noisy Acoustics
The LEED® green building certification program gives out points for naturally ventilating buildings, and it also gives out points for acoustics – especially for low levels of background noise levels. As the industry is finding out, naturally ventilated buildings create more opportunities for buildings to be penetrated by exterior noises, thus creating unintended loud background noise levels. I was interviewed by Buildings Magazine for their article, Fresh Air Creates Fresh Acoustical Concerns. Read the whole article here… http://www.buildings.com/ArticleDetails/tabid/3321/ArticleID/10021/Default.aspx
Video Blog | Healthcare Acoustics Nightmare

Reflections at Little Beaver Lake
On a beautiful autumn day a long time ago, I was on a glorious backpacking trip to Pictured Rocks National Lakeshore in Michigan’s Upper Peninsula. One still morning while rinsing off in Little Beaver Lake, I was alarmed to hear voices that sounded very near, as I was sporting my birthday suit. After quickly sinking into the water up to my neck, I searched for the people and to my relief found them on the opposite shore of the small lake, out of “detailed sight” range. That was a memorable lesson in how well water reflects sound. (more)
The Top 5 Acoustical Challenges of Church Video Venues
Church video venues are popping up everywhere. For many churches, they have become the go-to solution for solving the growth “problem”, which of course is a good problem to have. Church video venues are great for a number of reasons: they can offer an alternative worship music experience, they can keep a church unified by offering the same video sermon (live or recorded) to multiple venues, they can be a terrific option for landlocked churches, and much more. But what about the acoustics? What are some of the most pressing acoustical challenges of church video venues? (more)
Sound Healthcare 2010 – Upcoming Webinar
With only one stop left on our Midwest Tour, Sound Healthcare 2010 has already been presented to over 450 architects, engineers, designers, and healthcare professionals. But along the way something unexpected has been happening: people all across the country have been contacting us about attending the tour (which is a good problem to have). Some have gone as far as flying in to attend the seminars in person, but the majority have been asking about the possibility of a webinar presentation. Good news: if you are unable to make it to our last stop in Milwaukee on June 29th, we have a plan in the works to offer Sound Healthcare 2010 via webinar. But first, what are people saying about Sound Healthcare 2010? The following quotes are taken verbatim from our anonymous online survey:
Several weeks ago, a client invited me to a rehearsal in their highly reverberant space that ABD was hired to test and correct. I declined, as I already had plans to attend a play that evening at a different facility, and joked that during the performance I’d also be listening to sirens from the main street outside the theater. Nearly every time we attend a performance in this space, we hear sirens going by the building. Sure enough, on cue in Act II, “errrrrreeeeeerrrrrhhh” slices into the hall. My husband and I shake our heads. This is why sound isolation of performance spaces from outside noise intrusion is so important. (more)
Student Housing Acoustics – Noise in the Dormitory
Let’s play word association… Ready? Go: Academic… College… University… Higher Education… Acoustics! Did you picture the big wood paneled lecture hall filled with hundreds of students engaged in a lecture about world history, literature, or archeology? Yeah, me too… or at least that what I used to picture. (more)
The 2010 FGI Guidelines for Design and Construction of Health Care Facilities was published in January and adopted as building code by many states. How will you deal with the new noise, privacy, and acoustical requirements for healthcare facilities? Join us at SoundHealthcare 2010, a Health Care Acoustics Seminar, and find out what you must know about the new FGI Guidelines for HIPAA Compliance and LEED HC. There is no charge to attend this 90-minute seminar, but you must register in advance. The new guidelines are the culmination of over five years of collaborative work by researchers, architects, engineers, and acoustical consultants to solve the problems of speech privacy and excessive noise in hospitals. The guidelines are effective immediately for the design of all healthcare facilities. For perspective, consider the 2006 Guidelines which mandated single patient rooms in hospitals. As a result, single patient rooms are the absolute standard in healthcare design today. This was an overnight seismic shift in policy that affected all healthcare building projects. Well, the 2010 Guidelines are no different in their sweeping reforms, addressing a whole new dimension of healthcare design, namely: acoustics, noise, and HIPAA speech privacy laws. Register HERE to attend the seminar. (more)
Are Construction Administration Services Really That Important?
For many of our larger projects, we offer Acoustical Consulting Construction Administration Services as an additional option. Unfortunately, not all clients invest money on this service. Our frustration extends well beyond the revenue side of the project (the CA services are usually a very reasonable addition to the project budget, relative to Design Services). Sometimes our clients opt out of CA services, ending our involvement with the project after a review of the construction drawings and the specifications. We find that many clients view the additional services as non-essential. After all, “all the information is in the drawings and the specifications.” I would completely agree with the sentiment in an ideal world, but experience has shown this world is rarely, if ever, ideal. There are some clients, however, that have welcomed this form of service from our company, and I’d like to share one of their successes. (more)
Kachur to Speak at Audio Engineering Society
Every audio engineer must have a thorough understanding room acoustics to effectively perform their job. Mandy Kachur, Senior Consultant at Acoustics By Design, will discuss the fundamentals of acoustics for both large and small spaces at an upcoming meeting of the Audio Engineering Society. The discussion will focus on room modes, sound absorption, sound reflection, sound diffusion, sound isolation, and reverberation time. (more)
