Determination of Material Acoustic Features Using Small Samples

Abstract:

A new method to determine acoustic absorption in-situ is described in this paper. For practical consideration, this measurement can be performed on small samples (square of 60x60cm). This paper describes all the steps needed to obtain results: device setup, recording, signal processing.
