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 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 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 کاملPrediction of the Reverberation Time in Rectangular Rooms with Non- Uniformly Distributed Sound Absorption
SUMMARY The aim of this paper is first to review the best known reverberation time formulae and then to show that the reverberation time cannot be thereby predicted accurately in cases mostly encountered in practice, where the sound field is not diffuse. Introducing a correction to Fitzroy's formula allows better prediction of the reverberation time in the case of non-uniformly distributed soun...
متن کاملPrediction of the Reverberation Time in Rooms with Non Uniform Absorptions Using a Diffusion Model
The acoustical comfort is now a comfort’s criterion which is taken into from the conception. The designers need therefore accurate tools to predict the acoustic quality of enclosures. Most of the acoustical comfort criteria are based on the reverberation time. When the room has proportionate dimensions and an uniform absorption, the statistical theory through Sabine or Eyring formulas allows go...
