Abstract
Public address systems or other systems for emitting audio signals, like music, speech or announcements, in different locations like supermarkets, schools, universities, and auditoriums are widely known. In one embodiment, invention proposes a system for emitting an audio signal in an environment. The system includes an audio source for providing the audio signal and at least one loudspeaker for emitting the audio signal. The system also includes at least one microphone for receiving an acoustic signal from the environment. The acoustic signal is based on the audio signal and may comprise disturbing components. The system also includes an analyzing module for analyzing the acoustic signal and for providing an intelligibility measure from an objective intelligibility measure method. The intelligibility measure is used as a feedback signal.
