A Space-Time Adaptive Processing Method Based on Sparse Reconstruction of Reverberation Interference
Xibei Gongye Daxue Xuebao, 2020 Aiming at the problem of how to obtain reverberation samples and estimate their covariance matrix in the space-time adaptive processing(STAP) of sonar system, a new space-time adaptive processing method is proposed based on sparse reconstruction of ...

2025 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW)Abstract In the Colombian peace referendum, the 2016 accord with the FARC guerrilla, which sought to end fifty years of war, was rejected by 50.2% of voters. The referendum created new identity divides between ‘Yes’ and ‘No’ voters, product of political “narrative wars” which intersected with ...

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

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

Effects of reverberation on speech intelligibility in noise for hearing-impaired listeners
Royal Society Open Science, 2022 Reverberation can have a strong detrimental effect on speech intelligibility in noise. Two main monaural effects were studied here: the temporal smearing of the target speech, which makes the speech less understandable, and the temporal smearing of the ...
