Electronic Transduction for Acoustic Sensors

Chapter 10 was concerned mainly with the mechanical response of a sensing element to sound. In the following, we focus on the problem of how to convert that mechanical motion into an electronic signal. Because the mechanical sensing element must normally be very compliant, the design of the electronic transduction can result in significant forces applied that has a marked influence on the sensor motion. As a result, great care must often be taken to ensure that the transduction system leads to the desired performance.
