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.
How Today’s Teachers Use Classroom Display Technology
Kids today have it all: the cell phone, the iPod, the iPad, the internet, digital cameras, video games, laptops – ahhh!!! With all this stimuli, teachers have to battle to win the ever-decreasing attention spans of their students. And any teacher knows the statistics of how students learn: most of what they get their hands on (tactile learning), some of what they see (visual learning), and little of what they hear (aural learning). The good news is that new classroom display technology enables teaches to fire on all cylinders and teach fluidly while using all three methods of communication. So, how are teachers doing it? (more)
Football Stadium Sound System Design | How to Control the Friday Night Roar
It’s 7pm on Friday night in the middle of September. You’re sitting down with your significant other to a nice refreshing beverage on your back porch. All is calm. It’s a beautiful evening. Suddenly a not-so-distant voice floats through your backyard let you know that #58 has just tackled #23 on the 35 yard line. You are, once again, thankful that your peaceful and idyllic life has been interrupted by the sound system from the local High School football game. No…you wish there was some way to contain that sound to the stadium where it’s supposed to be (NOT in my backyard)! (more)
Restaurant Noise – A Big Deal to Food Critics
Over the years we’ve used this blog to try and get the word out that acoustics can be very important when designing a restaurant and that the assistance of a qualified acoustical consultant during the design phase will save the proprietor both time and money while ensuring the ambience is top notch. So just how important is acoustics in a restaurant? I spent a little time looking around at recent restaurant reviews in Chicago and Detroit to see what I could find… do the critics notice? (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
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:
Saving Money with Health Care AVL Design
The new 2010 FGI Guidelines for Design and Construction of Health Care Facilities recommend sound reinforcement systems in healthcare environments. As such, we often get the question: how do you save money on audio-visual systems in the health care sector? Well, there are many practical ways to cut cost without cutting quality, and as independent consultants we often work with our clients to understand how to do just that. Here are a few good ideas that will help with the bottom line: (more)
Digital Signage System Design 101
Digital signage is making its way into stores and businesses everywhere: hotels, department stores, grocery stores, universities, churches, funeral homes, you name it. As audio-visual designers, we are hired to offer digital signage design services for a wide variety of industries. One of the first questions we always ask our clients is who is this for? Who are you trying to communicate with? Without a target you will never know if your investment succeeded. (more)
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)
Whitespace Frequency Update for Wireless Microphones and the FCC
The world of wireless microphones continues to evolve and become more complicated with every passing day. Just a brief re-cap of the last couple years: The FCC has passed a series of rules over the last few years to move the analog TV stations out of the 700MHz band and force them to broadcast all digital signals. The 700MHz band was then sold off at auction to private companies. This band of frequencies was one of the most popular for wireless microphones and the auction meant that this band could no longer be used for wireless mics. The latest rule from the FCC mandates that all secondary users of frequencies in this range must cease operation by June 10, 2010, regardless of whether there is specific interference. (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)
