Research abstract
This proposal seeks to explore the use of a multi-resonator, directional MEMS microphone as an enabling technology for ANC ear plugs. The basic strategy is to use force-balanced feedback of the MEMS transducer into an adjacent speaker to produce zero noise at the MEMS transducer in sub-bands of interest. This strategy does NOT employ the use of a DSP, making it a potentially powerful technology for ANC ear plugs.
