Nonlinear Coc 3 . Nonlinear Cochlear Signal Processingand Masking in Speech PerceptionJ
There are many classes of masking, but two major classes are easily defined: neural masking and dynamic masking. Neural masking characterizes the internal noise associated with the neural representation of the auditory signal, a form of loudness noise. Dynamic masking is strictly cochlear, and is associated with cochlear outerhair-cell processing. This form is responsible for dynamic nonlinear ...

متن کاملSignal processing of acoustic signals in the time domain with an active nonlinear nonlocal cochlear model
A two space dimensional active nonlinear nonlocal cochlear model is formulated in the time domain to capture nonlinear hearing effects such as compression, multitone suppression and difference tones. The micromechanics of the basilar membrane (BM) are incorporated to model active cochlear properties. An active gain parameter is constructed in the form of a nonlinear nonlocal functional of BM di...
متن کاملNonlinear Cochlear Signal Processing and Masking in Speech Perception
Auditory masking is critical to our understanding of speech and music processing. There are many classes of masking, but two major classes are easily defined. These two types of masking and their relation to nonlinear (NL) speech processing and coding are the focus of this chapter. The first class of masking, denoted neural masking, is due to internal neural noise, characterized in terms of the...
متن کاملStatistical Noise Compensation for Co
A statistical noise compensation algorithm is proposed for cochlear implant processing to improve cochlear implant patients’ speech performance in noise. With the well-known environmental model for speech in additive noise, the MMSE (minimum mean square error) estimation of clean speech signals was derived according to the noisy speech observation based on a linear approximation of the original...
