Wavevector-Frequency Analysis with Applications to Acoustics

Abstract

This monograph presents an approach to the description and analysis of acoustic fields and systems that parallels and extends one developed by electrical engineers to describe and analyze electrical signals and systems. This approach, called wavevector-frequency analysis, complements traditional methods of acoustics. Wavevector-frequency analysis is simply the description and interpretation of a space-time field or system in terms of the Fourier conjugates of the independent spatial and temporal variables of the field or system. The Fourier conjugate of the spatial vector variable is called the wavevector, and the Fourier conjugate of the time variable is the frequency. The formalism of this approach to acoustics evolved over the course of an extended research effort to understand and characterize certain acoustic fields associated with turbulent flow. A brief description of this research effort will put the evolution of this approach in perspective.
