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...
متن کاملBlind 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...
متن کاملAn Improved Algorithm for Blind Reverberation Time Estimation
An improved algorithm for the estimation of the reverberation time (RT) from reverberant speech signals is presented. This blind estimation of the RT is based on a simple statistical model for the sound decay such that the RT can be estimated by means of a maximum-likelihood (ML) estimator. The proposed algorithm has a significantly lower computational complexity than previous ML-based algorith...
متن کاملPerformance Comparison of Algorithms for Blind Reverberation Time Estimation from Speech
The reverberation time, T60, is one of the key parameters used to quantify room acoustics. It can provide information about the quality and intelligibility of speech recorded in a reverberant environment, and it can be used to increase robustness to reverberation of speech processing algorithms. T60 can be determined directly from a measurement of the acoustic impulse response, but in situation...
متن کاملLow Variance Blind Estimation of the Reverberation Time
The reverberation time is a key feature for describing the acoustic properties of a reverberant room. It can be computed from a measured Room Impulse Response but in many applications it has to be estimated blindly. Existing blind methods give accurate estimates but they often exhibit high variance across different speakers. In this paper, a low variance blind estimator of the reverberation tim...
