Low-echo choir, frog voice recognition, acoustic fire extinguisher

October 12, 2005

What are the differences between amateur and professional choirs? Is it possible to aim different sounds at specific seats in a concert hall? Do chimpanzees have some basic mathematical ability that tells them when they are outnumbered and should keep quiet? Can ultrasound interact with audible music in such a way as to enhance listeners' enjoyment of the music? Are student musicians in marching bands at risk for hearing loss?

These and other questions are addressed in lay-language papers for the joint meeting of the Acoustical Society of America (ASA) and NOISE-CON 2005, the annual conference of the Institute of Noise Control Engineering. The meeting will be held October 17-21, 2005 at the Hilton Minneapolis Hotel (1001 Marquette Avenue, Minneapolis, MN 55403)

Even if you cannot travel to Minneapolis, the detailed descriptions in the lay-language papers, along with contact information and supplemental visuals and sound files, enable you to cover the meeting from your desk. We encourage you to contact presenters as soon as you'd like, even before they head off to the meeting.

The following text lists some examples of lay language papers and additional meeting topics.
