Industrial Noise Mitigation Strategies
We were recently called in to help with controlling the noise levels at an engine test facility. I went to the site to take noise measurements in various areas of the facility. The problem was not within the test cells, but from all the external equipment needed to run the cells from air compressors, to dynamometer drives, to engine exhaust vents. The sound levels were not above the OSHA requirements but were definitely loud enough to warrant some noise mitigation. So what are the key considerations for industrial facility noise control?

Classroom Audio-Visual Technologies that Work
“It depends.” This is probably my most frequent response I give when people ask me a tech-related question. Why? Because the answer to the question will vary depending on circumstances, factors, and requirements. So when someone asks me, “What’s the best AV technology to put into a classroom?” My answer usually is, “It depends.” What we first need to know is what the appropriate type and quantity of technology is in order to support the curriculum and teaching style of the school.

Medicare Funding Linked To Patient Satisfaction Scores
How important is acoustics in hospitals? Just ask Medicare. A recent Washington Post article highlights how Medicare reimbursement payments for hospitals will be linked to patient satisfaction scores (such as Press Ganey Patient Satisfaction Surveys). What does this have to do with acoustics? As it turns out, acoustics is the worse scoring section of patient satisfaction surveys nationwide! (more)
Seven Common Acoustical Mistakes and Misconceptions
Acoustics really is a complicated subject. Many of our recommendations need to be formed on a case-by-case basis, and some of that advice is based on principles that are not very intuitive. So here is a short list of common acoustical misconceptions: (more)
Sound System Commissioning and Equalization
What is the most important step in designing a sound system? Of course, every step is important, but I might argue that the final equalization is perhaps the most critical step, and often the most overlooked. Assuming a good design has been put together on paper and that the system has been installed as it was intended to be, it’s then time to put the finishing touches on everything. Equalizing (or commissioning) a large sound system is the final step in this complex process. (more)
