Abstract (en)
A first sound output unit exposes the hearing of the user to sound. A second sound output unit comprised of a signal generator/signal analyzer (GA) and a loudspeaker (LS) transmits an ultrasonic test signal to the surrounding area. A microphone (M) receives an answer to the test signal. An independent claim is also included for a room acoustic determining method.
