Abstract
A measurement system and method combine an audio announcement system with a plurality of spaced apart wirelessly coupled devices which evaluate speech intelligibility of audio output from loudspeakers of the audio announcement system. Processing can take place at some or all of the devices as well as at a common control element. Evaluations can be based on use of a method which maps to a Common Intelligibility Scale.
