Acoustics, Commercial Spaces and the Post-COVID World


In recent months my company has seen an uptick in requests to consult on acoustics solutions and installations in commercial spaces.

A seemingly innocuous post and an ensuing comment by a connection on the platform generated an internal dialogue that I’m not sure I’ve completely resolved. I share it here because it may not only have ramifications […]

The Golden Rules of Sound System Implementation and Design


Disclaimer: This is one of those topics that seems to require periodic reminders and refreshers. Why this is the case is one of the great mysteries of the AV life, but we seem to lose sight of the core principals reasonably regularly, and thus — the following is your scheduled reminder that the foundational rules […]

RE-ENFORCEMENT — What is the Goal?


(Author’s Note: The topic for this article was originally suggested by a comment from Barry McKinnon of MC Squared Design Group, North Vancouver, BC., Canada.) OK, ladies and gentlemen, it’s time for some serious military grade explosive driven myth busting! MYTH #1: Sounds reinforcement is a 20th century development. We have a tendency to think […]

Cleaner, Brighter and Articulate — It Is Possible, Part 1


A Little Physics At the normal sea level atmospheric pressure of 14.7 pounds-per-square-inch, 59 degrees F, dry air (< 50 percent relative humidity), sound travels one mile every five seconds in round numbers — so in 2.5 seconds, sound will cover a distance of half a mile. In NFL football, that’s just enough time to […]

Intelligibility and Acoustics: A Conflict Resolved?


It’s the Law The astonishing thing about the laws of physics and the mathematically derived acoustical parameters that govern sound reproduction is that, despite considerable effort by many well meaning or at least well motivated individuals and manufacturers over the last 150+ years, they simply haven’t changed, and, just in case you think there is […]
