Situational Awareness

Have you noticed the dramatic rise over the last two-plus years in corporate AV/IT client demand for collaborative technology, huddle spaces and similar functionality? It’s a hot buzz word in the upper echelons of corporate management and HR departments. The thought process for most companies goes something like this: Senior management decides that: “We need […]

Murphy Was an Optimist

The most often ignored or forgotten problem in AV/IT systems can be summed up in this quote from Benjamin Franklin: “By failing to prepare you are preparing to fail.” Technically speaking, a failure is declared when the system does not meet its desired objectives. Therefore we can consider any system that cannot meet minimum performance […]

Gravity

There are, within our space-time continuum, some immutable constants. For example, we can be assured that the earth will revolve on its axis every 24 or so hours and produce a sunrise and a sunset. In the sound system world, the number of absolutes is far more constrained by reality but there is one that, […]

No Freebies

Unless your media consumption habit is restricted to non-ad supported content, you will probably find the following experiment somewhat intriguing, if not downright disturbing. The next time you want to kill an hour doing non-work (and don’t we all sometimes), turn on any commercial broadcast channel, preferably either in the afternoon or late night and […]

DIY Acoustics: A Cautionary Tale

acoustic-egg-crates-0418.jpg

AUTHOR’S NOTE: In the year or so that I have been writing this column for rAVe’s house of worship publication, the majority of the articles have been how to or problem/solution oriented, with an educational and information focus. A number of those have concentrated on room acoustics and acoustic treatment areas (specifically, on intelligibility here […]

RE-ENFORCEMENT — What is the Goal?

greek-theater-0318.jpg

(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 […]

If It’s Too Loud, It’s Too Loud!

too-loud-0318.jpg

Some four decades ago, loudspeaker technology and the ability to generate sound pressure levels (SPL) above the recognized threshold of human hearing damage collided. As an industry, we had finally reached a level of electroacoustic and mechanical performance that was the audio equivalent of mutually assured destruction in nuclear warfare terms. Not only could manufacturers […]

New Construction — Room Acoustics, Part 2

fred-acoustics-featured-1117.jpg

In the first part of this two-part series, published in September, a wide variety of acoustical solutions and issues specifically focused on dealing with a space that already exists were discussed. Although the basic concepts and applications outlined in that article apply regardless, the issues and problems of a new building are in many ways […]

A Rant on Publishing by Dr. Frederick Ampel

ampel-food-1117.jpg

Normally, my various rAVe contributions are carefully and specifically focused on a problem, or a solution or a combination of both. The articles are always written with a singular focus — providing valuable information and solid, proven answers gathered from four-plus decades of real-world experience to the kind of problems AV professionals in both the […]

A 500 Million Dollar Mistake

dollar-drain-1017.jpg

In the previous rAVe HOW article, we discussed the value and application of acoustical treatment(s) to almost any existing house of worship (HOW) facility. Unless acoustics was considered and incorporated when the building was created, it is very likely that acoustical issues were not properly dealt with or solved. This is especially true for the […]

A $250 Million Epic Fail and the Wonders of Fly-By Wire

A3oo-series-typical-cocpit-displays-0917.jpg

Read a related piece by Dr. Ampel about artificial intelligence and the parallels between airplanes and audio. Why are we looking at the aircraft industry and their now decades long journey through automation, computerized systems, and software? BECAUSE, the problems, disasters, failures and the issues these raised mirror those within our own industry in a […]
