Methods of Measuring the Reverberation Time

The goal of this paper is to compare the results of reverberation time measurements obtained with different well-established methods used for this type of measurements, as well as some additional ones which could serve as in situ tool when standard methods are not available. The methods compared in this paper include integrated impulse response measured with pink noise, exponential sweep and MLS, balloon bursts, interrupted pink noise and the B&K filtered burst method. In order to make the comparison, the measurements were performed in two acoustically very different spaces - a damped listening room and a rather reverberant hallway. The results were evaluated according to dynamic range criterion as well.
