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

Metasurfaced Reverberation Chamber [PDF]

open access: yesScientific Reports, 2018
AbstractThe concept of metasurfaced reverberation chamber (RC) is introduced in this paper. It is shown that by coating the chamber wall with a rotating 1-bit random coding metasurface, it is possible to enlarge the test zone of the RC while maintaining the field uniformity as good as that in a traditional RC with mechanical stirrers.

Research on reverberation characteristics analysis and suppression methods for active continuous detection [PDF]

open access: yesMATEC Web of Conferences, 2019
Compared with the traditional active detection with monopulse periodic emission mode, active continuous detection has the advantages of large emission duty ratio and continuous acquisition of process information.

Cortical Sensorimotor Reverberations [PDF]

open access: yesNeuron, 2015
In this issue of Neuron, Manita et al. (2015) report that reciprocal excitatory interactions between higher-order frontal motor cortex and primary sensorimotor cortex might play a key role in hindlimb sensory perception in mice.

Linear Frequency Modulated Reverberation Suppression Using Non-Negative Matrix Factorization Methods, Dechirping Transformation and Modulo Operation

open access: yesIEEE Access, 2020
In this study, we propose a reverberation suppression algorithm for linear frequency-modulated (LFM) pulse sonar systems using a non-negative matrix factorization (NMF) method.

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).

Simulation of sonar reverberation signal considering the ocean multipath and Doppler effect

open access: yesFrontiers in Marine Science, 2023
In order to achieve accurate modeling and simulation of sonar reverberation signals, four types of multi-path underwater reverberation models are established considering Doppler effect under the condition of separating the sound source and hydrophone ...

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.
