Underwater Reverberation Suppression via Attention and Cepstrum Analysis-Guided Network
Active sonar systems are one of the most commonly used acoustic devices for underwater equipment. They use observed signals, which mainly include target echo signals and reverberation, to detect, track, and locate underwater targets. Reverberation is the

Blind binary masking for reverberation suppression in cochlear implants. [PDF]
A monaural binary time-frequency (T-F) masking technique is proposed for suppressing reverberation. The mask is estimated for each T-F unit by extracting a variance-based feature from the reverberant signal and comparing it against an adaptive threshold.

Radon–full-waveform inversion for suppressing scalp reverberation and skull-induced aberration in transcranial photoacoustic computed tomography [PDF]
Photoacoustic computed tomography is promising for noninvasive imaging of cerebral function but is limited by skull-induced acoustic aberrations. Moreover, strong superficial signals from the scalp often produce reverberations within the skull, which ...

Reverberation Suppression in Echocardiography Using a Causal Convolutional Neural Network
While ultrasound imaging has seen vast technical advances over the last decades, trans-thoracic echocardiography still suffers from image quality degradation caused by acoustic interaction with inhomogeneous tissue layers between the transducer and the ...
