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 7):
The method of  claim 1 , wherein the system ( 1 ) comprises an echo canceler ( 22 ) connected to the output line ( 6 ) and/or to the input line ( 10 ), and the method further comprises the steps of:\n (a 3 ) setting the microphone ( 8 ) gain to a high value, in particular to its maximum value; (b 3 ) providing a third speaker signal in the output line ( 6 ) such as to deliver a white noise signal to the speaker ( 4 ) via the echo canceler ( 22 ) causing the speaker ( 4 ) to produce sound; (c 3 ) delivering a fourth speaker signal simultaneously with the third speaker signal on the output line ( 6 ) directly to the speaker ( 4 ) bypassing the echo canceler ( 22 ); (d 3 ) receiving the sound generated by the speaker ( 4 ) within the elevator car ( 2 ) with the microphone ( 8 ) generating a third microphone signal; (e 3 ) determining whether the third speaker signal is present in the received third microphone signal; and (f 3 ) in case the third speaker signal is not present in the received third microphone signal, backing-off the microphone ( 8 ) gain and repeating steps (b 3 ) to (f 3 ).
