Abstract
A measurement system and method combine an audio announcement system with a plurality of spaced apart sensors to evaluate intelligibility of audio output from loudspeakers of the audio announcement system. 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 an appropriate speech intelligibility index method.
