How to test Digital MEMS Microphones
It is increasing common to find microphones being used in communication devices, consumer electronics, cars and household appliances; especially digital MEMS microphones. Typically, these are arranged as an array of multiple microphones. Thus the localization of a person speaking (Beamforming/Noise Cancellation) can be achieved.
From the point of view of the production test engineer this poses various challenges; the generation of a homogeneous sound field, the parallel processing of several channels, and the interpretation of the data obtained. This webinar therefore explains the basic operation of digital MEMS microphones and demonstrates strategies and approaches to testing them.
