Claim Text:
1. A method for noise testing a micro-electro-mechanical system (MEMS) microphone, the method comprising: positioning a film frame in a testing apparatus, the film frame including a film adhered to an array of MEMS microphones and covering an acoustic port of each MEMS microphone in the array of MEMS microphones; connecting an alignment socket to a substrate of the MEMS microphones, the alignment socket coupling to one or more contact pads of each MEMS microphone in the array of MEMS microphones to provide a power connection and a MEMS microphone output connection to each MEMS microphone; measuring, at a control unit, an output signal from the MEMS microphone output connection to obtain noise performance data; and recording the noise performance data in memory.
