The method is based on the psychophysical tuning curve (PTC) but estimates the shape of the PTC from the parameters of a hearing model, namely f\n                    <jats:sub>e<\/jats:sub>\n                    , and degree of outer hair cell loss. It chooses the masker frequency and level for each trial to be highly informative about the model parameters in the context of previous data. The procedure was tested using 14 ears from eight subjects previously diagnosed with high-frequency dead regions. The estimates of f\n                    <jats:sub>e<\/jats:sub>\n                    agreed well with estimates obtained using \u201cFast PTCs\u201d or more extensive measurements from an earlier study. On average, 33 trials were needed for the estimate of f\n                    <jats:sub>e<\/jats:sub>\n                    to fall and stay within 0.3 Cams of the final \u201ctrue\u201d value on the equivalent rectangular bandwidth-number scale. The time needed to obtain a reliable estimate was 5 to 8\u2009min. This is comparable to the time required for Fast PTCs and short enough to be used when fitting a hearing aid. Compared with Fast PTCs, the new method has the advantage of using yes-no judgments rather than continuous B\u00e9k\u00e9sy tracking. This allows the slope of a subject\u2019s psychometric function and thus the reliability of his or her responses to be estimated, which in turn allows the test duration to be adjusted so as to achieve a given accuracy.\n                  <\/jats:p>","DOI":"10.1177\/2331216518788215","type":"journal-article","created":{"date-parts":[[2018,7,19]],"date-time":"2018-07-19T08:17:12Z","timestamp":1531988232000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["A Hearing-Model-Based Active-Learning Test for the Determination of Dead Regions"],"prefix":"10.1177","volume":"22","author":[{"given":"Josef","family":"Schlittenlacher","sequence":"first","affiliation":[{"name":"Department of Experimental Psychology, University of Cambridge, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard E.","family":"Turner","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Cambridge, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian C.
