Zusammenfassung:	An acoustic measurement device for a disc drive, the measurement device having a form factor the same as the disc drive's form factor. The device has at least one microphone on an exterior surface of its housing and appropriate circuitry within the housing connecting the at least one microphone to an external device, such as a digital analog converter. As an example, an acoustic measurement device that is a surrogate for a 3½ inch disc drive can have 12 microphones.
