APPARATUS AND METHOD FOR MEASURING PLURALITY OF LOUDSPEAKERS AND MICROPHONE ARRAY

摘要

PROBLEM TO BE SOLVED: To provide an acoustic measurement device for speakers arranged at different positions in a listening area.SOLUTION: An acoustic measurement device for speakers arranged at different positions in a listening area includes: a test signal generator 10 for generating a test signal for a speaker; a microphone device 12 configured to receive a plurality of different sound signals in response to one or more speaker signals emitted by one speaker among a plurality of speakers in response to the test signal; a controller 14 for controlling emissions of the speaker signals by the plurality of speakers and for handling the plurality of different sound signals so that a set of sound signals recorded by the microphone device is associated with each speaker of the plurality of speakers in response to the test signal; and an evaluator 16 for evaluating the set of sound signals for each speaker to determine at least one speaker characteristic for each speaker and for indicating a speaker state using the at least one speaker characteristic for the speaker. The microphone device includes a plurality of microphones and a mechanical support.
