Removing redundancy in speech by modeling forward masking
… to extract those primary cues. However, speech masking, especially forward masking, should be considered and modeled when we extract the primary cues. In this thesis, we propose a forward masking model and integrate it into the AI-gram. The forward masking model consists of an RC feedback loop, …

Auditory brainstem response latency in noise as a marker of cochlear synaptopathy
… and brainstem, we show that the effect of masking noise on the latency of the more robust ABR wave-V mirrors changes in ABR wave-I amplitude. In our human cohort, the effect of noise on wave-V latency predicts perceptual temporal sensitivity. Further, we show evidence that ABR wave-V …

Current steering and electrode spanning with partial tripolar stimulation mode in cochlear implants
… and perceptual levels (i.e., psychophysical forward masking pattern). Consistent with the model predictions, pitch-ranking results verified the feasibility and efficacy of the proposed stimulation modes in eliciting distinctive pitches for CI users. Pitch increased when the centroid of …

Development of Cochlear Nonlinearities in Normal and Tshr Mutant Mice
… aspects of peripheral auditory function, a forward masking paradigm was used to generate ABR derived tuning curves. If one assumes that the tip of tuning curves represents the activity of a nonlinear element, or elements, of cochlear transduction, and that the tail portion of the curve is …

Thalamocortical forward modulation in the auditory cortex
Auditory masking is a psychoacoustic phenomenon with strong physiological correlates in the central auditory system such as in the primary auditory cortex. The caveat of conventional two-tone paradigms in testing the neurophysiology of forward masking (i.e., forward suppression) is that tones are …

Primary neuronal degeneration in the guinea pig effects on spontaneous rate-type
… range, response adaptation, and recovery from forward masking, were indistinguishable from responses recorded from unexposed controls. The only physiological abnormalities were revealed in the population statistics: in high-frequency regions where low- SR (<20sp/sec) fibers are 47% of the …
