Title:
APPARATUS AND METHOD FOR MEASURING A PLURALITY OF LOUDSPEAKERS AND MICROPHONE ARRAY
Document Type and Number:
WIPO Patent Application WO/2011/121004
Kind Code:
A3
Abstract:
An apparatus for measuring a plurality of loudspeakers arranged at different positions comprises: a test signal generator (10) for generating a test signal for a loudspeaker; a microphone device (12) being configured for receiving a plurality of different sound signals in response to one or more loudspeaker signals emitted by a loudspeaker of the plurality of loudspeakers in response to the test signal; a controller (14) for controlling emissions of the loudspeaker signals by the plurality of loudspeakers 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 loudspeaker of the plurality of loudspeakers in response to the test signal; and an evaluator (16) for evaluating the set of sound signals for each loudspeaker to determine at least one loudspeaker characteristic for each loudspeaker and for indicating a loudspeaker state using the at least one loudspeaker characteristic for the loudspeaker. This scheme allows an automatic, efficient and accurate measurement of loudspeakers arranged in a three-dimensional configuration.
