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)
Acoustics By Design, an independent acoustical consulting and audio-visual design firm headquartered in downtown Grand Rapids, was recently selected by the Michigan Business & Professional Association as one of “West Michigan’s 101 Best and Brightest Companies to Work For.” 2010 marks the fourth consecutive year that Acoustics By Design (ABD) has received the award.

Take The Poll. What is the Biggest Challenge Facing LEED?
Let’s face it, the LEED Green Building Rating System™ is facing some big challenges. The much heralded LEED for Healthcare program was supposed to be released in early 2009, but it is still sitting on the shelf unreleased. The LEED for Schools program has not been met with wide acceptance (since its release in 2007, only 26 schools have been certified under the program, as of this blog posting. See for yourself). And across the industry we are hearing of people who want to build projects to LEED specs, but without LEED certification. Whether or not that’s a good thing, is a topic of controversy. (more)
Mechanical Background Sound in Exam Rooms
January 2010 held a highly anticipated milestone for acoustical consultants. The definitive guide called 2010 FGI/ASHE Guidelines for Design and Construction of Health Care Facilities has a greatly expanded acoustics section in this year’s edition. How will you deal with the new noise, privacy, and acoustical requirements for healthcare facilities? Join us at SoundHealthcare 2010, a Health Care Acoustics Training Seminar, and find out what you must know about the new FGI Guidelines for HIPAA Compliance and LEED HC. This is a brand new chapter in the 2010 FGI Guidelines, which went from a solitary partition transmission loss table in prior issues to an eighty page guideline that comprehensively covers exterior noise, acoustical finishes, background noise, sound isolation, vibration, sound masking systems, audio systems and alarms. As a result, acoustical consultants are hoping that architects and engineers will appreciate the breadth and importance of acoustics and consequently incorporate acoustical design early in a project when it is most cost effective.

Anechoic Chambers – What They’re All About
So what in the world are anechoic chambers? In short, they are the consultant’s and manufacturer’s best friend when it comes to acoustics. Anechoic chambers are primarily used for a variety of acoustical measurements that determine just how much noise a product is making. These chambers are most notable for their strange appearance… their foam filled walls, ceilings, and sometimes floors of spikes look a bit like a Nerf torture chamber; if you filled them with plastic balls they’d be a hit attraction at your local Chuck E Cheese. But alas the soft spikes are not meant for harm or play but rather to absorb as much sound as possible, so that you can measure the true sound emitted or reflected off of whatever noise source you are interested in.
