Recall of Reverberant Speech in Quiet and Four-Talker Babble Noise

open access: yesBrain Sciences, 2021
Using behavioral evaluation of free recall performance, we investigated whether reverberation and/or noise affected memory performance in normal-hearing adults. Thirty-four participants performed a free-recall task in which they were instructed to repeat

Hierarchical reverberation mapping [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2014
Abstract Reverberation mapping (RM) is an important technique in studies of active galactic nuclei (AGN). The key idea of RM is to measure the time lag τ between variations in the continuum emission from the accretion disc and subsequent response of the broad-line region (BLR).

Interaural Coherence Estimation for Speech Processing in Reverberant Environment

open access: yesApplied Sciences, 2020
Interaural coherence is used to quantify the effects of reverberation on speech, and previous studies applied the conventional method using all previous time data in the form of an infinite impulse response filter to estimate interaural coherence.

Radiated Immunity Testing of a Device with an External Wire: Repeatibility of Reverberation Chamber Results and Correlation with Anechoic Chamber Results [PDF]

open access: yes, 2003
We present the experimental radiated immunity results of an electronic device with an external wire obtained in reverberation and anechoic chambers. Repeatability and reproducibility of reverberation chamber measurements are investigated by repeating the

Impact of Temperature and Relative Humidity on Reverberation Time in a Reverberation Room

open access: yesBuildings, 2022
Changes in acoustic parameters measured in a room may depend on the location and orientation of the sound source and microphones or on the reverberation conditions of the room.

Evaluation and Verification of Bottom Acoustic Reverberation Statistics Predicted by the Point Scattering Model [PDF]

open access: yes, 1992
The point scatteringmodel offers a parameterization of the reverberation probability density function (pdf) in terms of the coefficient of excess (kurtosis) and a coherent component represented by a harmonic process with random phase.

Determination of the Reverberation Time Using the Measurement of Sound Decay Curves

open access: yesApplied 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 ...
