ABSTRACT

A characteristic of electroacoustic devices is that they are able to convert signals between the electrical, mechanical, and acoustical domains with retained time histories. The transducer may be considered a gateway between two domains, the primary and secondary “sides.” For physical reasons, it is not possible to achieve a perfect transduction since noise and linear, as well as nonlinear, distortion will usually affect the signal during transduction. It is useful to think of transducers as systems composed of a mechanical part, the “pure” transduction, and then an electric part or the reverse.
