摘要：An apparatus for measuring a plurality of loudspeakers arranged at different
positions comprises: a test signal generator (10) for generating a test signal for aloudspeaker; a microphone device (12) being configured for receiving a plurality ofdifferent sound signals in response to one or more loudspeaker signals emitted by aloudspeaker 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 loudspeakersand for handling the plurality of different sound signals so that a set of sound signalsrecorded by the microphone device is associated with each loudspeaker of the pluralityof loudspeakers in response to the test signal; and an evaluator (16) for evaluating theset of sound signals for each loudspeaker to determine at least one loudspeakercharacteristic for each loudspeaker and for indicating a loudspeaker state using the atleast one loudspeaker characteristic for the loudspeaker. This scheme allows anautomatic, efficient and accurate measurement of loudspeakers arranged in a three-dimensional configuration.
