Late reverberation suppression using U-nets
CoRR, 2021 In real-world settings, speech signals are almost always affected by reverberation produced by the working environment; these corrupted signals need to be \emph{dereverberated} prior to performing, e.g., speech recognition, speech-to-text conversion, compression, or general audio enhancement.

Remote Sensing, 2023 The detection performance of active sonar is often hindered by the presence of seabed reverberation in shallow water. Separating the reverberations from the target echo and noise in the received signal is a crucial challenge in the field of underwater ...

Roomprints for forensic audio applications [PDF]
, 2013 09.12.13 KB. Ok to add accepted version to spiral, IEEE.A roomprint is a quantifiable description of an acoustic environment which can be measured under controlled conditions and estimated from a monophonic recording made in that space.

High-Resolution Wideband Waveform Design for Sonar Based on Multi-Parameter Modulation
Remote Sensing, 2023 The design of transmitting waveforms is an effective way to improve the detection performance of sonar systems. For the problem of high-range sidelobe when designing reverberation-resistant waveforms, this paper proposes a high-resolution wideband ...

Suppression of reverberation artifact by subtraction imaging [PDF]
The Journal of the Acoustical Society of America, 1990 Reverberations in ultrasound pulse-echo signals are the result of parallel specular reflectors that are perpendicular to the incident sound beam. The multiple reflections within the space between the reflectors cause a decaying pulse train of echoes to be superimposed on the returned echoes due to other structures. In a medical ultrasound B-scan, these

"Good-but-Imperfect" electromagnetic reverberation in a VIRC [PDF]
, 2011 Novel theoretical probability density functions (PDF) of electromagnetic fields inside reverberation chambers operating in a “good-but-imperfect‿ regime have been recently reported. The present work reports on the application and assessment of these PDFs

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

Field Statistics in a One-Dimensional Reverberation Chamber Model [PDF]
, 2008 This work focuses on building a fairly simple yet physically appropriate 1D model for a Reverberation Chamber which claims to be able to analytically predict the statistical behavior of such a chamber, without forsaking to the benefits of deterministic ...
