Electrical analogies have often been found useful in the modeling of acoustical systems. There are two alternatives. The sound pressure can be represented by voltage and the volume velocity by current, or alternatively the sound pressure is replaced by current and the volume velocity by voltage. Use of electrical analogies is discussed in chapter 11 of the Handbook of Acoustics [1]. They have been widely used in loudspeaker design and are in fact perhaps most useful in the understanding and design of transducers such as microphones where acoustic, mechanical, and electrical systems are present together and where an overall equivalent electrical circuit can be formulated (see Handbook of Acoustics [1], chapters 111–113).

Beranek makes considerable use of electrical analogies in his books [10, 11]. In chapter 14 in the Handbook of Acoustics [1] their use in the design of automobile mufflers is described. Chapter 10 in this book also reviews the use of electrical analogies in muffler and silencer acoustical design.
