Digital Acoustic Intensity Measurements

Part of the International Centre for Mechanical Sciences book series (CISM, volume 296)

Abstract

A measurement method (digital acoustic intensity measurements) is proposed, which, in contrast to the classical methods, enables the measurement of the acoustic intensity in the near field of a vibrating structure. As will be demonstrated the grafic representation of the near field intensity vector is a useful resource in the experimental study of the sound radiation mechanisms, in identifying noise sources or in estimating the sound contribution of different subcomponents of a complex source. As such it is a unique tool to identify the radiation mechanism of vibrating structures and to study the complex relation between structural vibrations and radiated sound.
