Development of a Super-Wide-Range Microphone for Sound Recording

A new design for a super-wide-range microphone overcomes the conventional tradeoff between noise and bandwidth. Rather than reduce the size of the sensing element to extend the bandwidths to 100 kHz, this design explicitly takes advantage of high-frequency scattering by the microphone body and resonances of the diaphragm. This extends the frequency range, while still preserving the low noise of larger transducers. Laboratory measurements of the resulting omnidirectional electrostatic microphone validate the design approach.
