MEMS Microphones for Active Noise Cancellation Applications

PublishTime：2023-06-28

●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. CONCLUSION
●Microphones for active noise cancellation have a specific set of requirements to enable a high-performance system. The microphone is the first device in the ANC signal chain so any compromises on the microphone’s performance will propagate downstream and limit the noise cancellation capability. MEMS microphones provide unique advantages in relative phase response, acoustic overload point and size over existing ECMs for ANC.
