The Fourier Analyzer for Acoustical Measurements

The paper describes an implementation of the Fourier analyzer for acoustical measurement. The classical concept of system frequency response estimation using continuous noise system excitation is extended to use of the periodic random phase multisine excitation. It is shown that better S/N and lower bias ERRORS can be obtained in multipath acoustic environments then it is possible with a classical Fourier analyzer.
