This chapter reviews various measurement techniques for sound intensity, recording and reproduction, and the Doppler effect. The intensity of a sound wave at any point is defined as the energy per second that is carried across unit area normal to the direction of travel of the wave at that ...
Principles of Measurement of Sound Intensity Sound pressure and particle velocity in a sound field can both be expressed as functions of thevelocity potentialof the field, but the relationship between the two depends upon the type of sound field, and is not unique. Therefore it is necessary to ...
