Zusammenfassung:	The present invention relates to a microphone sensor amplitude consistency testing device and method. The testing device comprises a sound source section, a test section and a grating; one end of the sound source section is a sound source inlet, and the other end of the sound source section is connected to the test section; a microphone fixing frame is fixed by means of a connecting rod to the end of the test section connected to the sound source section; a slot is formed in the middle of the connecting rod; the other end of the test section is connected to the grating; exhaust ports are formed in the surface of the grating, and a hand lever is fixed in the middle of the grating. According to the testing method, a volume sound source releases stable sound signals; microphones to be tested receive these signals and process these sound signals into digital signals; after the digital signals are processed, frequency response function curves are output, and error analysis is performed on response data of the micr
