It produces a text file and a pdf file to document the reverberation time estimate. Two measurement method can be used 1) speaker on-speaker off method, and 2) balloon pop method.
A basic procedure for the measurement two methods is given in the Readme file.
The speaker on-speaker off method has been found to be far more accurate than the balloon pop method.
The balloon pop method can often have more than 50% error below 1000 Hz.
reverb_time. m calculate the reverberation times for 1/3 octave band time records. Time records using the random time test signals from makelNHANESNoisesm_ed. m from (Also on Matlab Central File Exchange) are ideal for reverberation time measurements using the speaker on- speaker off method.
The same file can be processed several times with the balloon pop method, to roughly estimate the reverberation time in each 1/3 octave band.
