What is a "Wide Dynamic Range" Microphone and why does it matter to my design?
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 radios.
