Acoustical Measurements by Time Delay Spectrometry
A new acoustical measurement technique has been developed that provides a solution for the conflicting requirements of anechoic spectral measurements in the presence of a reverberant environment. This technique, called time delay spectrometry, recognizes that a system-forcing function linearly relating frequency with time provides spatial discrimination of signals of variable path length when perceived by a frequency-tracking spectrum analyzer.
