Associations Of The Medial Olivocochlear Reflex And Speech-In-Noise Abilities In Normal Hearing Adult Listeners: A Systematic Review, Imari J. Greaves
Associations Of The Medial Olivocochlear Reflex And Speech-In-Noise Abilities In Normal Hearing Adult Listeners: A Systematic Review, Imari J. Greaves
Dissertations, Theses, and Capstone Projects
This systematic review analyzed the research concerning the medial olivocochlear reflex (MOCR) and speech-in-noise abilities in normal hearing adult listeners. In an attempt to understand the underlying difficulties in this population, the following research questions were proposed: 1) Does the research indicate that the magnitude of MOC suppression measured via OAEs is related to a normal hearing subject’s ability to recognize speech-in-noise? 2) Are MOC effects measured via OAEs lateralized? Is there a right ear advantage as suggested by Khalfa, Morlet, Micheyl, Morgon & Collet (1997)? Ten studies met the standards for inclusion for this review. Analysis of the research …
A Systematic Review Of Occupational Music-Induced Hearing Loss, Lilach Gez Saperstein
A Systematic Review Of Occupational Music-Induced Hearing Loss, Lilach Gez Saperstein
Dissertations, Theses, and Capstone Projects
The prevalence of noise induced hearing loss (NIHL) is a public health concern with government regulations (i.e. OHSA, NIOSH) in place to protect employees in occupational settings. Sound pressure levels (SPL) of various industries have been measured and exposure dosages monitored as per the national regulations. Previous research has demonstrated that occupational exposure to loud noise has led to audiometric evidence of NIHL. Thus, it raises the question about the impact of occupational exposure to music on hearing. For the purposes of this capstone, literature pertaining to occupational music exposure levels, and the effects on both hearing threshold levels and …
Using Otoacoustic Emissions To Evaluate Efferent Auditory Function In Humans, Simon Henin
Using Otoacoustic Emissions To Evaluate Efferent Auditory Function In Humans, Simon Henin
Dissertations, Theses, and Capstone Projects
The auditory system continually adapts to changes in the acoustic environment over short periods of time. This fine-tuning of its dynamics is mediated in part by the medial olivocochlear (MOC) bundle, a neural feedback loop which aids in the regulation of cochlear micro-mechanics. The ability to measure the response of the MOC system in humans may provide significant insight into unique cochlear functions, such as its sharp frequency selectivity and wide dynamic range. In humans the efferent system can be investigated non-invasively using otoacoustic emissions (OAEs). However, how OAEs can best be used to evaluate efferent function, the pitfalls associated …
