Smart Self-Configuring Miniature Windscreen

A novel and promising solution is proposed for a smart self-configuring miniature windscreen. The proposed solution includes a mechanical windscreen, MEMS microphones, and a DSP windscreen. The mechanical windscreen will be designed by numerical simulation. The finite-element method will be utilized to simulate the effect of different shapes of windscreens on the aerodynamics in the vicinity of the diaphragm. The windscreen of optimal shape and material will be tested and verified on a test bed which physically simulates the real operating environment. The DSP windscreen will be implemented by a microphone array, our unique noise-reduction algorithms, and a single DSP chip. The proposed low-cost solution can totally remove wind noise without distortion of other signals.
