MEMS microphones with the capability to capture
very high sound pressure acoustic waves (loud noises) with high fidelity hold
the potential not only to improve user experience in audio capture, but also
make acoustic detection viable for a range of applications that might have
previously been unsuitable for such methods. Coupling high SPL performance with
a low noise floor (expressed by high SNR) yields microphones with a very wide
dynamic range. Such wide dynamic range microphones are particularly compelling
when considered alongside the benefits of MEMS technology. We will discuss
specific design considerations for such wide dynamic range microphones and the
various applications that might benefit from such high performance.

Who should attend:
Electrical or acoustics engineers
with microphones in their design. This webcast will be valuable to long time
users of microphones who may not yet be familiar with MEMS microphones and also
to electrical engineers with little or no previous experience with microphones
in particular. Engineers working on acoustic sensing applications in extreme
environments (outdoors, hard to replace equipment, loud environments, etc.) will
be particularly interested. Sample applications might include IP cameras,
security panels, flow monitoring, photoacoustic gas detection, or fire/police
