Overview of Signal Processing in Acoustics.

Signal processing is used to some extent in all areas of acoustics such as extracting relevant information from acoustic measurements made either in the laboratory or in the field, processing signals, and/or synthesizing data to cope with demanding tasks raised in acoustics. Techniques range from simple classical approaches based on Fourier transforms and Gaussian noise to sophisticated model‐based techniques that incorporate physical/parametric models of the acoustical system. In this talk we highlight new approaches to signal processing that could be applied to a broad variety of acoustical problems. Examples of each approach will be shown to illustrate the class of problems addressed and the performance.
