Application of Adaptive System Modeling on Impulse Response and Anechoic Transfer Function Measurement in Reverberant Environment
Measurement of the impulse response and anechoic transfer function of electroacoustical systems such as loudspeakers is very important issue. Although impulse response of the test object can be measured in an anechoic chamber, in same cases it is not convenient. A solution for measurement of direct and early sound anechoic spectra in a normally reverberant environment is Heyser&#8217 ; s time delay spectrometry, based on linear sine sweep. This paper proposes application of adaptive system modeling and random noise excitation instead. Measurements were performed on a loudspeaker, and computation is shown of the energy-time curve and the cumulative spectral decay plot.
