Positive and negative ear-canal pressures (relative to ambient pressure) reduced the emission amplitude by 3\u20136 dB. A spectral analysis of the emissions revealed that the effect of ear-canal air pressure is that of a high-pass filter with a cutoff frequency of 2600 Hz and a slope of 4 dB\/oct. The spectral changes are the expected effect of an increase in stiffness of the middle ear and were independent of pressure polarity and click level. Ear-canal air pressure substantially reduced the reproducibility of the emission waveform, in many cases rendering the emission indistinguishable from background noise. The implication of these findings for hearing screening applications is that a high false alarm rate may occur in normal-hearing patients with intratympanic air pressures that are significantly different from ambient pressure.<\/jats:p>","DOI":"10.1121\/1.403695","type":"journal-article","created":{"date-parts":[[2005,10,13]],"date-time":"2005-10-13T20:30:19Z","timestamp":1129235419000},"page":"2091-2095","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":70,"title":["Effect of ear-canal air pressure on evoked otoacoustic emissions"],"prefix":"10.1121","volume":"91","author":[{"given":"Susan L.","family":"Naeve","sequence":"first","affiliation":[{"name":"Department of Otolaryngology, University of Minnesota, Box 283 UMHC, Minneapolis, Minnesota 55455"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert H.","family":"Margolis","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, University of Minnesota, Box 283 UMHC, Minneapolis, Minnesota 55455"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel C.","family":"Levine","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, University of Minnesota, Box 283 UMHC, Minneapolis, Minnesota 55455"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric M.","family":"Fournier","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology, University of Minnesota, Box 283 UMHC, Minneapolis, Minnesota 55455"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"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\/91\/4\/2091\/11598321\/2091_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/91\/4\/2091\/11598321\/2091_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,7,19]],"date-time":"2023-07-19T21:39:25Z","timestamp":1689802765000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/91\/4\/2091\/663287\/Effect-of-ear-canal-air-pressure-on-evoked"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1992,4,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1992,4,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.403695","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1992,4]]},"published":{"date-parts":[[1992,4,1]]}}}
