Reverberation suppression algorithm for LS beamforming based on Wiener post-filter

open access: greenDianzi Jishu Yingyong, 2018
Reverberation causes speech signal time and frequency to blur, and speech is difficult to understand when serious. In order to improve the speech quality, this paper presents a least squares beamforming reverberation suppression algorithm with Wiener ...

Linear frequency modulated reverberation suppression using time series models

open access: diamondIndonesian Journal of Electrical Engineering and Computer Science, 2022
When active radar and <span>sonar systems are used for target detection and tracking, boosting target detection, and tracking efficiency is the most important challenge in real-time reverberation. To eliminate reverberation when transmitting linear frequency modulated (LFM) signals, this study employs time series techniques such as autoregressive

Ocean Reverberation Suppression via Matrix Completion with Sensor Failure [PDF]

open access: green, 2020
In the ocean environment, reverberation is a common and strong interference which significantly degrades the performance of target bearing estimation. Meanwhile, sensor failure is inevitable in actual sonar deployment as the underwater scene is complicated. Therefore, it is a challenge for target detection in the ocean reverberation with sensor failure.

Methods for reverberation suppression utilizing dual frequency band imaging [PDF]

open access: bronzeThe Journal of the Acoustical Society of America, 2013
Reverberations impair the contrast resolution of diagnostic ultrasound images. Tissue harmonic imaging is a common method to reduce these artifacts, but does not remove all reverberations. Dual frequency band imaging (DBI), utilizing a low frequency pulse which manipulates propagation of the high frequency imaging pulse, has been proposed earlier for ...

Ultrasonic Reverberation Clutter Suppression Using Multiphase Apodization With Cross Correlation [PDF]

open access: greenIEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2016
Despite numerous recent advances in medical ultrasound imaging, reverberation clutter from near-field anatomical structures, such as the abdominal wall, ribs, and tissue layers, is one of the major sources of ultrasound image quality degradation. Reverberation clutter signals are undesirable echoes, which arise as a result of multiple reflections of ...

Binaural speech intelligibility for combinations of noise, reverberation, and hearing-aid signal processing. [PDF]

open access: yesPLoS ONE
Binaural speech intelligibility in rooms is a complex process that is affected by many factors including room acoustics, hearing loss, and hearing aid (HA) signal processing. Intelligibility is evaluated in this paper for a simulated room combined with a

Suppression of reverberation in hearing aids

open access: green, 2006
Reverberation is a sound degradation that cause reduced speech intelligibility. For a hearing impaired person wearing an hearing aid, this may cause communication problems and thus, the motivation for a dereverberation algorithm for hearing aids is clear.
