Children’s recall of words spoken in their first and second language:Effects of signal-to-noise ratio and reverberation time [PDF]
Frontiers in Psychology, 2016 Speech perception runs smoothly and automatically when there is silence in the background, but when the speech signal is degraded by background noise or by reverberation, effortful cognitive processing is needed to compensate for the signal distortion ...

Determination of the Reverberation Time Using the Measurement of Sound Decay Curves
Applied Sciences, 2023 In the measurements of reverberation time, measurement methods of different accuracy are used depending on the room. For ordinary rooms, the measurements are made using the interrupted noise method, which consists of determining the decay curve after ...

TOPOLOGICAL REVERBERATIONS IN FLAT SPACE–TIMES [PDF]
International Journal of Modern Physics A, 2000 We study the role played by multiply-connectedness in the time evolution of the energy E(t) of a radiating system that lies in static flat space–time manifolds ℳ4 whose t= const spacelike sections ℳ3 are compact in at least one spatial direction.

Experimental Validation of the Model of Reverberation Time Prediction in a Room
Buildings, 2022 It is well known that the uncertainty of input data has a great influence on the accuracy of room acoustics simulations. The aforementioned accuracy is significantly influenced by the selection of the acoustic properties of room-delimiting materials ...
