Frequency and reverberation response of a pipe resonator.

A frequency and reverberation response of a circular pipe resonator are studied by newly developed techniques of the signal compression method and the calculation method of reverberation response from impulse response. By these methods, reverberation decay curves for very narrow band input signals are obtained and dips in reverberation curves are observed. These dips appear when two frequency response peaks are influenced equally by narrow band input signals. These measuring methods would be useful for room acoustics when fine structure of reverberation decay curve is desired.
