This book was released on 2007-12-20 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cochlea does not just pick up sound, it also produces sounds of low intensity called Otoacoustic Emissions (OAEs). Sounds produced by healthy ears – either spontaneously or in response to stimuli - allow researchers and clinicians to study hearing and cochlear function noninvasively in both animals and humans. This book presents the first serious review of the biological basis of these otoacoustic emissions.

This book was released on 2013 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Background: Excessive noise exposure can lead to noise induced hearing loss (NIHL) and hearing conservation programmes are essential to prevent occupational hearing loss. These programmes rely on monitoring hearing using pure tone audiometry. However, audiometry is not very sensitive and only detects a permanent hearing loss after significant injury has occurred. Distortion product otoacoustic emissions (DPOAEs) are generated by cochlear non-linear physiological processes associated with the outer hairs cells that underpin detection of sound, thus DPOAEs have promise as a tool to detect and monitor cochlear hair cell damage in NIHL. The DPOAE has two components, one generated at the point of interaction between the primaries (generator), the second reflected from the characteristic place of the DPOAE frequency (reflected). Some of the variability in DPOAE is believed to result from the interaction of the components, termed the DPOAE fine structure, and extracting the components may reduce the variability and improve the sensitivity of the DPOAE to injury. This study investigated the feasibility and reliability of a new approach to separating the DPOAE components, and their relationship to hearing measures in people with and without exposure to noise. Methods: Logarithmically swept primaries with a least-squares-fit (LSF) analysis were used to separate the DPOAE components, and the approach was evaluated and optimised in normally hearing subjects. Two studies followed that investigated the components of the DPOAE and how they correlate with behavioural measures of hearing. Firstly, in subjects (n=16) with 'normal' hearing (20 dB HL), both behavioural measures of the auditory filter (notched-noise maskers) and threshold were compared to the components of the DPOAE. In the second study subjects (108 men) with a mixture of thresholds, noise exposure and age were recruited and then divided into two equal sized and age matched groups (noise exposed and non-noise exposed) based on a detailed history of self-reported noise exposure. The DPOAE components were compared to audiometric threshold and behavioural measures of compressive nonlinearity using Schroeder-phase masked thresholds. Results: Overall, psychoacoustic measures of auditory filter and cochlear non-linearity were influenced by audiometric threshold, and exhibited no relationship with DPOAE level in subjects with 'normal' hearing (

Download or read book The effect of hearing loss on neural processing written by Jonathan E. Peelle and published by Frontiers Media SA. This book was released on 2015-06-03 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efficient auditory processing requires the rapid integration of transient sensory inputs. This is exemplified in human speech perception, in which long stretches of a complex acoustic signal are typically processed accurately and essentially in real-time. Spoken language thus presents listeners’ auditory systems with a considerable challenge even when acoustic input is clear. However, auditory processing ability is frequently compromised due to congenital or acquired hearing loss, or altered through background noise or assistive devices such as cochlear implants. How does loss of sensory fidelity impact neural processing, efficiency, and health? How does this ultimately influence behavior? This Research Topic explores the neural consequences of hearing loss, including basic processing carried out in the auditory periphery, computations in subcortical nuclei and primary auditory cortex, and higher-level cognitive processes such as those involved in human speech perception. By pulling together data from a variety of disciplines and perspectives, we gain a more complete picture of the acute and chronic consequences of hearing loss for neural functioning.

Book excerpt: The International Symposium on Hearing is a prestigious, triennial gathering where world-class scientists present and discuss the most recent advances in the field of human and animal hearing research. The 2015 edition will particularly focus on integrative approaches linking physiological, psychophysical and cognitive aspects of normal and impaired hearing. Like previous editions, the proceedings will contain about 50 chapters ranging from basic to applied research, and of interest to neuroscientists, psychologists, audiologists, engineers, otolaryngologists, and artificial intelligence researchers.

This book was released on 2013 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the hallmarks of auditory processing disorder (APD) is difficulty listening in background noise. This difficulty maybe related to the function of the medial olivocochlear (MOC) efferent system, which is hypothesized to provide an anti-masking effect that might aid in speech processing in noise. To test this hypothesis, we investigated the efferent anti-masking hypothesis via efferent-induced changes in the baseline levels of distortion product otoacoustic emissions (DPOAE) in a group of subjects suspected of having APD with speech-in-noise deficits matched for age and gender with a control group with less speech-in-noise deficits. There was no significant difference in audiometric thresholds between the groups. We examined not only the typical composite DPOAE, but also the two major components (overlap and reflection components), which determine the overall DPOAE level. We hypothesized that the group with speech-in-noise deficits would show reduced efferent effects relative to the control group. The findings did not support the efferent anti-masking hypothesis as efferent-induced changes in the composite DPOAE signal and the overlap component did not differ significantly between the two groups, but the statistical power was low. The separation of the two DPOAE components was beneficial in detecting efferent effects at the high frequency region where the DPOAE levels were lowest, and efferent effects were variable. The mean baseline levels and SNR of composite DPOAE and the overlap component were lower in the group with speech-in-noise deficits than the control group. This difference was not significant, but the statistical power was low. In addition, no significant correlations were found between performance on speech-in-noise tests and DPOAE change due to efferent activation across groups. Factors that might explain why the efferent anti-masking hypothesis was not supported are discussed.
Download or read book Auditory Signal Processing written by Daniel Pressnitzer and published by Springer Science & Business Media. This book was released on 2006-03-14 with total page 537 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the papers that were presented at the XIIIth International Symposium on Hearing (ISH), which was held in Dourdan, France, between August 24 and 29, 2003. From its first edition in 1969, the Symposium has had a distinguished tradition of bringing together auditory psychologists and physiologists. Hearing science now also includes computational modeling and brain imaging, and this is reflected in the papers collected. The rich interactions between participants during the meeting were yet another indication of the appositeness of the original idea to confront approaches around shared scientific issues. A total of 62 solicited papers are included, organized into 12 broad thematic areas ranging from cochlear signal processing to plasticity and perceptual learning. The themes follow the sessions and the chronological order of the paper presentations during the symposium. A notable feature of the ISH books is the transcription of the discussions between participants. A draft version of the book is circulated before the meeting, and all participants are invited to make written comments, before or during the presentations. This particularity is perhaps what makes the ISH book series so valuable as a truthful picture of the evolution of issues in hearing science. We tried to uphold this tradition, which was all the easier because of the excellent scientific content of the discussions.
