Subjective Speech Intelligibility Measurements in a Light Aircraft Cabin Under Laboratory Conditions

The quality of speech communications inside the aircraft cabin is one of the primary issues in aircraft safety. After comprehensive field investigations of light aircraft cabin noise during flight and the results of speech intelligibility obtained, attempt was made to create simulated cabin noise field inside the hull of a flight training device by using cabin noise audio clips digitally prerecorded in real environment. A group of qualified subjects was put under subjective speech intelligibility tests and the most significant results are presented.
