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 measuring methods

A Conversation with Makoto Fujita

X -ray crystallography is one of the best tools to determine a molecule’s structure. But it’s not much use when your cherished compound is a greasy smear that resolutely fails to crystallize. In 2013, Makoto Fujita of the University of Tokyo unveiled a method that offered hope to researchers struggling with stubborn samples. It relies on a metal organic framework (MOF), a highly porous lattice ...

A Time-variant Reverberation Algorithm for Reverberation Enhancement Systems

This paper presents a new time-variant reverberation algorithm that can be used in reverberation enhancement systems. In these systems, acoustical feedback is always present and time variance can be used to obtain more gain before instability (GBI). The presented time-variant reverberation algorithm is analyzed and results of a practical GBI test are presented. The proposed reverberation algori...
