Uncertainties of reverberation time estimation via adaptively identified room impulse responses.
This paper investigates the reverberation time estimation methods which employ backward integration of adaptively identified room impulse responses (RIRs). Two kinds of conditions are considered; the first is the "ideal condition" where the anechoic and reverberant signals are both known a priori so that the RIRs can be identified using system identification methods. The second is that only the...
متن کاملSimulation of time variant room impulse responses
For many applications such as acoustic echo compensation, adaptive noise reduction or acoustic feedback control it is of great interest to simulate reproducibly a real, time variant room. One approach to describe the transient behavior of a room is the generation of a physical room model, e.g. [l]. To identify the variation of a room impulse response with time an alternative concept is presente...
متن کاملColoration in Room Impulse Responses
A literature review concerning perception of coloration is presented. In the paper we also present a review of general psycho acoustic background material concerning auditory modeling including perception of timbre and amplitude modulation. Furthermore, some classical room acoustic measures for echo perception are considered. Finally, some of the simple engineering measures to rate coloration i...
متن کاملA Statistical Room Impulse Response Model with Frequency Dependent Reverberation Time for Single-Microphone Late Reverberation Suppression
Single-channel late reverberation suppression algorithms need estimates of the late reverberance spectral variance (LRSV) in order to suppress the late reverberance. Often the LRSV estimators are derived from a statistical room impulse response (RIR) model. Usually the late reverberation is modeled as a white Gaussian noise sequence with exponentially decaying variance. The whiteness assumption...
متن کاملBlind 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...
