Because the minimal hearing loss that is associated with older age may affect GN disruption differently than more significant hearing loss, the current study explored the contribution of minimal hearing loss associated with older age to GN disruption. GN disruption was measured using three masker-signal delays (25, 75, and 150\u2009ms) for three adult groups: younger participants with normal hearing (NH), older participants with minimal hearing loss, and older participants with sensorineural hearing loss. The role of underlying mechanisms was tested using a computational model for midbrain neurons. The primary result suggests that older listeners with mild threshold elevations that typically occur with age may be more susceptible to the deleterious effects of masker envelope fluctuations than younger listeners with NH. Results from the computational model indicate that there may be a larger influence of efferent feedback and saturation of inner hair cells on forward masking and GN disruption than previously considered.<\/jats:p>","DOI":"10.1121\/10.0017724","type":"journal-article","created":{"date-parts":[[2023,4,3]],"date-time":"2023-04-03T09:17:30Z","timestamp":1680513450000},"page":"1994","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":17,"title":["Inherent envelope fluctuations in forward masking: Effects of age and hearing loss"],"prefix":"10.1121","volume":"153","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6961-7584","authenticated-orcid":false,"given":"Marc A.","family":"Brennan","sequence":"first","affiliation":[{"name":"University of Nebraska-Lincoln 1 , Lincoln, Nebraska 68583, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8864-4457","authenticated-orcid":false,"given":"Adam","family":"Svec","sequence":"additional","affiliation":[{"name":"San Jos\u00e9 State University 2 , San Jose, California 95192, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Afagh","family":"Farhadi","sequence":"additional","affiliation":[{"name":"University of Rochester 3 , Rochester, New York 14642, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8782-5560","authenticated-orcid":false,"given":"Braden N.","family":"Maxwell","sequence":"additional","affiliation":[{"name":"University of Rochester 3 , Rochester, New York 14642, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurel H.","family":"Carney","sequence":"additional","affiliation":[{"name":"University of Rochester 3 , Rochester, New York 14642, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2023,4,3]]},"reference":[{"key":"2023081106421125300_c1","volume-title":"Specification for Audiometers","author":"ANSI","year":"2004"},{"key":"2023081106421125300_c2","volume-title":"Guidelines for Manual Pure-Tone Threshold Audiometry","author":"ASHA","year":"2005"},{"key":"2023081106421125300_c3","doi-asserted-by":"publisher","first-page":"1498","DOI":"10.3389\/fpsyg.2015.01498","article-title":"PsyAcoustX: A flexible MATLAB\u00ae package for psychoacoustics research","volume":"6","year":"2015","journal-title":"Front.
