Say What? Acoustics for College Cafeterias and Social Spaces
I was recently interviewed by College Planning & Management magazine for their article on “How schools can create cafeterias and other social spaces to shout about, not over?” These spaces are where university students come to dine, to study, to relax, and to socialize, so why are they always so loud? And more importantly, what can be done to optimize these spaces for sound? Read the full article here http://www.peterli.com/cpm/resources/articles/archive.php?article_id=2616.
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)
Video Blog | Healthcare Acoustics Nightmare
This is a fictional video we made to illustrate the many problems of acoustics, noise, and vibration in modern healthcare facilities. It shows why hospitals and health care facilities need acoustical engineers. © 2010, Acoustics By Design.
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:
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)
Acoustics from the Ancient Amphitheatre to the Modern Arena
In the days of the ancient Romans, crowds would gather by the thousands in the amphitheater to see a wide range of events: public ceremonies honoring brave soldiers, performances of dramatic presentations, or the gruesome games of the gladiators. Although the events were a visual extravaganza, the amphitheater and coliseum were also designed acoustically to allow the entire audience to hear. Fast forward two thousand years, and we still gather in large groups to see college graduations, rock concerts, sporting events, and more. Two of the primary senses that are titillating to the large masses still remain the same: visual and aural stimulation. (more)

An Opportunity Lost? GM’s Saturn Division – Success Squandered or Just Delayed?
Early in my career, I was a young acoustics engineer working at the General Motors “Noise and Vibration Laboratory” (NVL) where our function was to provide automotive noise and vibration control solutions to the various vehicle development teams. At one point, my job was to lead the design and development of the noise control (“Sound Package”) solutions for the original Saturn vehicle line. So when I saw the recent news about Roger Penske & Penske Automotive Group acquiring the Saturn brand from General Motors, I found myself thinking back on the glory days of Saturn: what made them so unique, and what solutions will bring them through the current economic recession?

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)
Acoustics, Patient Care, and The Healing Environment
The healthcare industry is booming and your healthcare costs are rising, so what do you get out of it? Well, besides higher monthly premiums and insurance costs, you do get one thing: choice. You have the freedom to choose between everything from primary care providers to hospitals to outpatient clinics to rehabilitation centers. And this choice is driving up the competition between healthcare providers causing them to place a higher priority on, well – you – getting you and keeping you as a loyal customer, uhm… I mean patient.

Binaural Recording with a Dummy Head
This past week, as we took acoustical measurements at the Calvin College Fine Arts Center in Grand Rapids, Michigan, a music teacher poked her head into the auditorium and asked if aliens had landed. “Well, not exactly”, I said. But I admitted that it did look and sound a lot like it. Binaural “dummy head” recording isn’t exactly something you see (or hear) everyday, so here is a brief glance at why this technique is used by acousticians. (more)
Acoustical Design for Contemporary Churches
The challenge with contemporary church architecture is that the term “contemporary” means a lot of different things to a lot of different people. For some, it means a praise band and a projector. For others, it means the service is full of drama, dance, video, interactive preaching, and more. With all the different styles, a lot of contemporary churches feel stuck in the middle with facilities that are in between “where it is” and “where it ought to be.” (more)
