Instrument identification through a simulated cochlear implant processing system
The signal processing used by cochlear implants is primarily designed to convey speech and environmental sounds, and can cause distortion of music. Although some studies of implanted listeners have demonstrated their limited ability to identify instruments, these results do not suggest whether the …

Noise reduction algorithms and performance metrics for improving speech reception in noise by cochlear-implant users
… speech reception by CI users since typical CI sound-processing strategies, like the STI, rely on the envelope signals in frequency bands spanning the speech spectrum. However, STI-based metrics have proven unsatisfactory for assessing the effects of nonlinear operations on the intelligibility …

Auditory event-related potentials and cognitive outcome after very preterm birth
… are neurophysiological measures of cortical sound detection, encoding, discrimination, and attentional processes. Abnormal AERPs have been associated with cognitive and behavioral problems. To date, there has been very little research into AERP in preterm infants. Therefore, our aim was to …

Structural and functional distinctions between auditory centers revealed with MRI in living humans
From brainstem to cortex, sound is processed in centers that are functionally and structurally distinct. In animals, invasive electrophysiology and histology has revealed these distinctions and, consequently, organizational principles behind sound processing. In humans, however, comparable …

Auditory brainstem response latency in noise as a marker of cochlear synaptopathy
… in environments with multiple competing sound sources can be challenging, even for listeners with normal hearing thresholds (NHT). This difficulty in "normal" listeners is thought to arise from central sites of the auditory system with the assumption that sound encoding at the auditory …

Sensor Drive Mobile application for health awareness The SSURE (Software System for User Running Evaluation) app for Android: a design that won’t let you down
… Vocoder technique was used to transform the sound to different speed without changing the pitch. Its sophisticated frequency-domain sound processing suits our project’s objective. To guide the implementation of these algorithms, several Software Engineering techniques have been used to manage …

Individual differences in supra-threshold auditory perception - mechanisms and objective correlates
… content and meaning from a single source of sound in a quiet background, the auditory system can use a small subset of a very redundant set of spectral and temporal features. In stark contrast, communication in a complex, crowded scene places enormous demands on the auditory system. …

Development of novel optical sensing-based digital stethoscopes and deep learning-based heart sound denoising algorithms
… stethoscopes and deep learning-based heart sound denoising algorithms. Cardiac auscultation is the act of listening non-invasively to the sounds of the heart. It provides insights into the mechanical activity of the heart, and the sounds produced by this activity can be recorded as a …

Noise practice in the digital age
… noise that is present as part of all forms of sound processing. Sound is the term that we use to refer to vibrations of air particles when they pass through a particular medium to the ear. In the field of music all forms of sound must pass through some form of medium in order to be audible. In …

Effects of Hearing Experience, Music Training and Spectral-Temporal Processing on Music and Speech Perception in Adult Cochlear Implant Users
… residual hearing can provide useful additional sound processing that can be used for optimizing and enhancing music perception. Suggesting the importance of preserving the hearing and clinically considering the hearing during mapping and rehabilitation sessions. Residual hearing and individual …

A mixed method investigation into the impact of activation therapy with and without word finding for people with aphasia
… by both prominent models of single word processing, interactive and modular. Analysis of meaning word finding difficulties and generalisation to words not targeted in therapy aligned more closely to the interactive models of conceptualisation of single word processing. Neither model …
