The Time Integral Basic to Optimum Reverberation Time

Short Reverberation Time Measurement

The measurement of short reverberation times poses different problems depending at the same time on difficulties of measurement and the sensitivity of the analysis techniques applicable to short signals. This article presents a toolbox, which allows a reliable estimation of reverberation time for small spaces, in a software environment, and using a lightweight system, designed for in-situ measu...

Blind Reverberation Time Estimation

This paper presents a method, which is able to give a blind estimation of the reverberation time of an enclosed space, using only the signal from two or more spatially distributed receivers, for example a binaural signal. There is no need for a controlled or known excitation signal, and there are no special requirements for the excitation signal. The method works with any kind of acoustic sourc...

Reverberation Time in "dead" Rooms

culation by the aid of a reliable formula, then, is an important aspect of applied acoustics. A reverberation time formula enables one to calculate the reverberation time once the volume, surface area and average absorption coefficient of the surface of the room are known; or if the reverberation time is measured it enables one to calculate the average coefficient of absorption of the surface t...

Blind estimation of reverberation time.

The reverberation time (RT) is an important parameter for characterizing the quality of an auditory space. Sounds in reverberant environments are subject to coloration. This affects speech intelligibility and sound localization. Many state-of-the-art audio signal processing algorithms, for example in hearing-aids and telephony, are expected to have the ability to characterize the listening envi...
