NoSo and NoS\u03c0 critical bands were derived from the bandlimited noise functions. A notched noise measure of the monaural critical band was also obtained for each ear. One hypothesis tested was that an asymmetrical monaural critical band would result in a relatively steep improvement of the NoS\u03c0 detection threshold as a function of decreasing masker bandwidth and would, therefore, be associated with a wider binaural critical band. This was hypothesized because the outputs of the left and right auditory filters would be more decorrelated the greater the interaural difference in the monaural critical band. However, as the noise bandwidth was narrowed, the decorrelation would lessen, resulting in a relatively steep improvement in NoS\u03c0 detection. Results indicated that the masking level difference (MLD) was smaller and that the monaural critical bands were generally wider in cochlear-impaired listeners. NoSo and NoS\u03c0 critical bands were somewhat larger in the cochlear hearing-impaired listeners having relatively wide monaural critical bands. There was a significant correlation between monaural critical band asymmetry and the NoS\u03c0 critical band; however, this correlation was insignificant when a control was employed for the critical band in the worse ear. Therefore, the present results did not support a strong association between monaural critical band asymmetry and the width of the NoS\u03c0 critical band.<\/jats:p>","DOI":"10.1121\/1.399420","type":"journal-article","created":{"date-parts":[[2005,10,13]],"date-time":"2005-10-13T19:34:09Z","timestamp":1129232049000},"page":"1720-1727","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":18,"title":["NoSo and NoS\u03c0 detection as a function of masker bandwidth in normal-hearing and cochlear-impaired listeners"],"prefix":"10.1121","volume":"87","author":[{"given":"Jon G.","family":"Staffel","sequence":"first","affiliation":[{"name":"The Division of Otolaryngology\/Head & Neck Surgery, University of North Carolina Medical School, Chapel Hill, North Carolina 27514"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"suffix":"III","given":"Joseph W.","family":"Hall","sequence":"additional","affiliation":[{"name":"The Division of Otolaryngology\/Head & Neck Surgery, University of North Carolina Medical School, Chapel Hill, North Carolina 27514"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John H.","family":"Grose","sequence":"additional","affiliation":[{"name":"The Division of Otolaryngology\/Head & Neck Surgery, University of North Carolina Medical School, Chapel Hill, North Carolina 27514"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Harold C.","family":"Pillsbury","sequence":"additional","affiliation":[{"name":"The Division of Otolaryngology\/Head & Neck Surgery, University of North Carolina Medical School, Chapel Hill, North Carolina 27514"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","container-title":["The Journal of the Acoustical Society of America"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/87\/4\/1720\/11373423\/1720_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/87\/4\/1720\/11373423\/1720_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,1]],"date-time":"2023-08-01T22:44:53Z","timestamp":1690929893000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/87\/4\/1720\/930812\/NoSo-and-NoS-detection-as-a-function-of-masker"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1990,4,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1990,4,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.399420","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1990,4]]},"published":{"date-parts":[[1990,4,1]]}}}
