Reverberation suppression in cochlear implants using a blind channel-selection strategy. [PDF]
J Acoust Soc Am, 2013 Reverberation severely degrades speech intelligibility for cochlear implant (CI) users. The ideal reverberant mask (IRM), a binary mask for reverberation suppression which is computed using signal-to-reverberant ratio, was found to yield substantial intelligibility gains for CI users even in highly reverberant environments (e.g., T60 = 1.0 s ...

Blind binary masking for reverberation suppression in cochlear implants. [PDF]
J Acoust Soc Am, 2013 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.

Reverberation Clutter Suppression Using 2-D Spatial Coherence Analysis. [PDF]
IEEE Trans Ultrason Ferroelectr Freq Control, 2022 Diffuse reverberation clutter often significantly degrades the visibility of abdominal structures. Reverberation clutter acts as a temporally stationary haze that originates from the multiple scattering within the subcutaneous layers and has a narrow spatial correlation length.
