A few human cases resulting from continuous, i.e., nonimpulsive noise, have been reported as reviewed by Ward [(1991). \u201cHearing loss from noise and music,\u201d presented at Audio Engineering Society, New York, October 4\u20138]. This paper updates that review by examining 11 cases in nine reports, from 1950 to 2006, with the intention of determining minimum exposures that may cause AT, including the potential risk of exposure to noise from magnetic resonance imaging machines. Diffuse-field related levels above 120\u2009dBA for 10\u2009s or more, or above 130\u2009dBA for 2\u20133\u2009s (values well above OSHA's unprotected exposure limits), can lead to AT. These cases appear to represent a susceptible fraction of the population, because much more intense exposures (e.g., 130\u2009dBA for 32\u2009min) have been tolerated by groups of volunteers who suffered only temporary threshold shifts. AT from continuous noise is unlikely to occur in OSHA-compliant hearing conservation programs, and probably rare enough in the general civilian population that clinical trials of drugs aimed at treating it are unlikely to be practical. AT from impulse noise, such as gunfire, which is specifically not the topic of the current work, is more amenable to clinical trials, especially in military settings.<\/jats:p>","DOI":"10.1121\/1.5132712","type":"journal-article","created":{"date-parts":[[2019,11,27]],"date-time":"2019-11-27T16:30:59Z","timestamp":1574872259000},"page":"3873-3878","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Acoustic trauma from continuous noise: Minimum exposures, issues in clinical trial design, and comments on magnetic resonance imaging exposures"],"prefix":"10.1121","volume":"146","author":[{"given":"Elliott H.","family":"Berger","sequence":"first","affiliation":[{"name":"Berger Acoustical Consulting , 221 Olde Mill Cove, Indianapolis, Indiana 46260, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert A.","family":"Dobie","sequence":"additional","affiliation":[{"name":"University of Texas Health Science Center at San Antonio, 7703 Floyd Curl Drive , San Antonio, Texas 78229, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2019,11,27]]},"reference":[{"key":"2023080210275203600_c1","doi-asserted-by":"publisher","first-page":"70","DOI":"10.1177\/019459989310800109","article-title":"Impedance audiometry and iatrogenic hearing loss","volume":"108","year":"1993","journal-title":"Otolaryngol.
