Less is known about its effects on the level dependence of selectivity that is so prominent a feature of normal hearing. The aim of the present study is to characterize such changes in nonlinearity as manifested in the auditory filter shapes of listeners with mild\/moderate hearing impairment. Notched-noise masked thresholds at 2 kHz were measured over a range of stimulus levels in hearing-impaired listeners with losses of 20\u201350 dB. Growth-of-masking functions for different notch widths are more parallel for hearing-impaired than for normal-hearing listeners, indicating a more linear filter. Level-dependent filter shapes estimated from the data show relatively little change in shape across level. The loss of nonlinearity is also evident in the input\/output functions derived from the fitted filter shapes. Reductions in nonlinearity are clearly evident even in a listener with only 20-dB hearing loss.<\/jats:p>","DOI":"10.1121\/1.1448516","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T14:10:47Z","timestamp":1027692647000},"page":"1330-1339","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":37,"title":["Auditory filter nonlinearity in mild\/moderate hearing impairment"],"prefix":"10.1121","volume":"111","author":[{"given":"Richard J.","family":"Baker","sequence":"first","affiliation":[{"name":"Human Communication and Deafness, School of Education, University Of Manchester, Oxford Road, Manchester\u2009M13\u20099PL, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stuart","family":"Rosen","sequence":"additional","affiliation":[{"name":"Department of Phonetics and Linguistics, University College London, Wolfson House, 4 Stephenson Way, London\u2009NW1\u20092HE, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023071323082152800_bak98"},{"key":"2023071323082152800_bak01","doi-asserted-by":"crossref","first-page":"43","DOI":"10.1080\/03005364.2001.11742730","article-title":"Evaluation of maximum-likelihood threshold estimation with tone-in noise masking","volume":"35","year":"2001","journal-title":"Br.
