MEMS Sensors - MEMS Microphones

In a typical audio application, a microphone is the device which captures sound waves as they are emitted from their source and passes them on to be converted into electrical signals for a variety of uses. In a noise cancellation application, microphones are used to register noise waves which need to be silenced. The microphones pass these waveforms on into the system to generate the anti-noise waveforms which are then emitted to cancel out the noise. Learn More
