AN-000056 – MEMS Microphones for Active Noise Cancellation Applications

MEMS microphones are an attractive choice to use in active noise cancellation (ANC) applications. They provide high-performance
audio-acoustic specifications in a small size, and have very stable part-to-part performance and across a part’s lifetime. A description of
specific performance characteristics and their relevance to ANC follows.
