Abstract
A method and device for detecting and locating a fault of a housing comprising: arranging at least two loudspeakers and at least two microphones therein; for each pairing of loudspeaker and microphone and a housing with no faults: measuring a reference frequency response of the sound transmission from the loudspeaker to the microphone; for each pairing and a housing with faults: measuring a present frequency response of the sound transmission; for each pairing: determining a difference frequency response as the difference between the present frequency response and the reference frequency response; for each possible combination of two pairings: calculating a correlation measure between the difference frequency responses of the pairings; and determining the combination with the highest correlation measure and, if the same loud-speaker or the same microphone appears in the pairings of this combination, then locating the fault as proximate to this loudspeaker or microphone.
