Psychoacoustics: Annoyance from Tonal vs. Broadband Sounds

by ABD Engineering and Design | Noise and Vibration

For today’s topic, let’s think of driving our car with the wind rushing by, when all of a sudden our attention is drawn by that annoying squeak coming from the dashboard. The changing of the squeak with time was the topic of a recent blog, but this time we’ll examine...

Industrial Paging System Safety Code Requirements

by ABD Engineering and Design | Noise and Vibration

Generally speaking, sound systems in industrial spaces are there to serve two purposes. One is to reproduce pages for people in the plant to hear. The second is to play background music for people to listen to. For years, it's been about that simple. An amplifier,...

Planning for Acoustical Separation of MRI Rooms in Hospitals

by ABD Engineering and Design | Noise and Vibration

In my last post, I discussed the acoustical design of hospital patient rooms, minimizing disturbance from noise produced by activity in the corridor, by phone calls and discussions at the nurses' stations, and by noise from nearby patient rooms. But that's only the...

An Opportunity Lost? GM’s Saturn Division – Success Squandered or Just Delayed?
