Acoustic Sensing

Acoustic sensors normally consist of two essential elements: (1) a mechanical structure that is intended to respond to the minute fluctuations in the medium in a sound field and (2) a means of transducing that response into an electronic signal. In this chapter, we will mainly concentrate on the analysis and design of a suitable structure to respond to these small motions of the medium. The problem of transducing that motion into an electronic signal will be considered in Chap.  11 .
