INTELLIGIBILITY TESTING FOR MONITORING OR PUBLIC ADDRESS SYSTEMS

摘要

An audible intelligibility system and method combine a public address system (10) with a plurality of spaced apart sensors (60s) to evaluate intelligibility of audio output from speakers (34s) of the public address system (10). Processing can take place at some or all of the sensors as well as at a common control element. Evaluations can be based on use of a pre-determined speech transmission index.
