The advent of instruments capable of measuring sound intensity, which represents the flow of energy in sound fields, has revolutionised audio-frequency acoustical metrology. Since publication of the first edition, two International Standards for the use of sound intensity for sound source power determination, and one International Standard for sound intensity instrumentation, have been published. A number of National Standards have also been developed. This second edition of Sound Intensity deals with all aspects of sound intensity and its measurement, from the basic theoretical analysis to...
