Automatic Loudspeaker Control (ALC). A Summary of Development and Design.

Abstract

The automatic loudspeaker control (ALC) senses ambient noise levels in a given space and automatically adjusts the loudspeaker output serving that space. This eliminates hazardous loudspeaker outputs in confined spaces and, more importantly, assures unimpaired reception of vital information. In addition to covering the design approach, system description, and planned system deployment, this report also provides a listing of ALC documents available from NOSC and appendices of the primary technical data and evaluations for the ALC.
