The increase in threshold in the combined-masker condition compared to the individual-masker conditions can be used to estimate compression. The signal was a 250 or 4000Hz tone burst and the maskers (M1 and M2) were bands of noise. Signal thresholds were measured in the presence of M1 and M2 alone and combined for a range of masker levels. The results were used to derive response functions at each frequency. The procedure was conducted with normal-hearing and hearing-impaired listeners. The results suggest that the response function in normal ears is similar at 250 and 4000Hz with a mid level compression exponent of about 0.2. However, compression extends over a smaller range of levels at 250Hz. The results confirm previous estimates of compression using temporal masking curves (TMCs) without assuming a linear off-frequency reference as in the TMC procedure. The impaired ears generally showed less compression. Importantly, some impaired ears showed a linear response at 250Hz, providing a further indication that low-frequency compression originates in the cochlea.<\/jats:p>","DOI":"10.1121\/1.2908297","type":"journal-article","created":{"date-parts":[[2008,6,7]],"date-time":"2008-06-07T23:19:51Z","timestamp":1212880791000},"page":"4321-4330","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":32,"title":["Estimates of compression at low and high frequencies using masking additivity in normal and impaired ears"],"prefix":"10.1121","volume":"123","author":[{"given":"Christopher J.","family":"Plack","sequence":"first","affiliation":[{"name":"Lancaster University Department of Psychology, , Lancaster LA1 4YF, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew J.","family":"Oxenham","sequence":"additional","affiliation":[{"name":"University of Minnesota Department of Psychology, , 75 East River Road, Minneapolis, Minnesota 55455"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea M.","family":"Simonson","sequence":"additional","affiliation":[{"name":"University of Minnesota Department of Psychology, , 75 East River Road, Minneapolis, Minnesota 55455"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catherine G.","family":"O\u2019Hanlon","sequence":"additional","affiliation":[{"name":"Newcastle University Institute of Neuroscience and School of Psychology, , Henry Wellcome Building, Newcastle Upon Tyne, Tyne NE2 4HH, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vit","family":"Drga","sequence":"additional","affiliation":[{"name":"University of St. Andrews School of Psychology, , St. Mary\u2019s College, South Street, St. Andrews, Fife KY16 9JP, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dhany","family":"Arifianto","sequence":"additional","affiliation":[{"name":"Lancaster University Department of Psychology, , Lancaster LA1 4YF, United Kingdom"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","reference":[{"key":"2023071307551480800_c1","doi-asserted-by":"publisher","first-page":"2034","DOI":"10.1121\/1.1397357","article-title":"Inner hair cell response patterns: Implications for low-frequency hearing","volume":"110","year":"2001","journal-title":"J.
