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...
متن کاملThe ensemble variance of pure-tone measurements in reverberation rooms.
Reverberation rooms are often used for measuring the sound power emitted by sources of sound. At medium and high frequencies, where the modal overlap is high, a fairly simple model based on sums of waves from random directions having random phase relations gives good predictions of the ensemble statistics of measurements in such rooms. Below the Schroeder frequency, the relative variance is muc...
متن کاملInvestigation on Simulation and Measurement of Reverberation for Small Rooms
This paper investigates the simulation of reverberation in a small room using image source method, Schroeder model, and Gardner model. It then compares the simulation results with measurement of reverberation in the real measurement room. It shows a large difference between the simulation and the real measurement of reverberation due to the over-simplified representation of the sound source, re...
متن کاملLearning to estimate reverberation time in noisy and reverberant rooms
The reverberation time, T60, is an important indicator of the reverberation strength in a room and has many applications in speech processing, such as dereverberation. However, the T60 must be blindly estimated if only reverberant speech is available. In this paper, we provide a learning based approach for T60 estimation. We treat the T60 estimation as a classification problem by dividing the T...
متن کاملSpeech segregation in rooms: effects of reverberation on both target and interferer.
Speech reception thresholds were measured to investigate the influence of a room on speech segregation between a spatially separated target and interferer. The listening tests were realized under headphones. A room simulation allowed selected positioning of the interferer and target, as well as varying the absorption coefficient of the room internal surfaces. The measurements involved target se...
