Abstract:
An acoustic elevator communication system ( 1 ) comprises a speaker ( 4 ) on an output line ( 6 ) and a microphone ( 8 ) on an input line ( 10 ), the speaker ( 4 ) and the microphone ( 8 ) being installed inside an elevator car ( 2 ); a sound generator ( 24 ) connected with the output line ( 6 ); and an adjustment unit ( 25 ). The adjustment unit ( 25 ) is configured for (A 1 ) driving the sound generator ( 24 ) for delivering a first speaker signal to the speaker ( 4 ), the first speaker signal in particular being a white noise signal causing the speaker ( 4 ) to produce white noise sound; (B 1 ) receiving the sound generated by the speaker ( 4 ) with the microphone ( 8 ) generating a first microphone signal; (C 1 ) determining acoustic resonances from the first microphone signal; (D 1 ) adjusting the speaker signal such as to eliminate the acoustic resonances in the first microphone signal.

Claim (Index 13):
The acoustic elevator communication system ( 1 ) of  claim 10 , wherein the adjustment unit ( 25 ) is further configured for\n (A 2 ) setting the gain of the speaker ( 4 ) to its maximum; (B 2 ) setting the gain of the microphone ( 8 ) to an intermediate value; (C 2 ) delivering a second speaker signal to the speaker ( 4 ); (D 2 ) receiving the sound generated by the speaker ( 4 ) in response to the second speaker signal with the microphone ( 8 ) generating a second microphone signal; (E 2 ) determining whether the second microphone signal is distorted; and (F 2 ) in case the second microphone signal is distorted, reducing the speaker ( 4 ) gain by a predetermined amount; (G 2 ) repeating steps (C 2 ) to (F 2 ) until the second microphone signal is not distorted.
