Impact noise was generated by striking a nail with a hammer and was digitally recorded. The acoustical power spectrum of the impact was determined and pink noise was filtered to produce a continuous noise stimulus with the same acoustic power spectrum. Pre-exposure auditory evoked response (AER) thresholds were obtained at 1, 2, 4, and 8 kHz on 16 adult chinchillas. The pool of animals was divided into two equal groups based upon pre-exposure AER thresholds. One group was exposed to impact noise and the other group to the filtered pink noise. Exposures were 4 h\/day for 5 days. Thirty days following the exposure, auditory evoked response thresholds were remeasured. Changes in auditory sensitivity were determined by subtracting the pre-exposure thresholds from the post-exposure thresholds. Hearing threshold shifts of the impact noise group were significantly greater (p&amp;lt;0.0001) than the hearing threshold shifts of the continuous noise group. These data indicate a need to more closely examine the parameters and effects of impact noise. There may be a need to develop expanded damage\u2013risk criteria for occupational exposure to impulse\/impact noise.<\/jats:p>","DOI":"10.1121\/1.401677","type":"journal-article","created":{"date-parts":[[2005,10,13]],"date-time":"2005-10-13T20:29:19Z","timestamp":1129235359000},"page":"1979-1985","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":58,"title":["Hearing loss in the chinchilla from impact and continuous noise exposure"],"prefix":"10.1121","volume":"90","author":[{"given":"Derek E.","family":"Dunn","sequence":"first","affiliation":[{"name":"U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, Division of Biomedical and Behavioral Science, Physical Agents Effects Branch, 4676 Columbia Parkway, C-27, Cincinnati, Ohio 45226"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rickie R.","family":"Davis","sequence":"additional","affiliation":[{"name":"U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, Division of Biomedical and Behavioral Science, Physical Agents Effects Branch, 4676 Columbia Parkway, C-27, Cincinnati, Ohio 45226"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carol J.","family":"Merry","sequence":"additional","affiliation":[{"name":"U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, Division of Biomedical and Behavioral Science, Physical Agents Effects Branch, 4676 Columbia Parkway, C-27, Cincinnati, Ohio 45226"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John R.","family":"Franks","sequence":"additional","affiliation":[{"name":"U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, Division of Biomedical and Behavioral Science, Physical Agents Effects Branch, 4676 Columbia Parkway, C-27, Cincinnati, Ohio 45226"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","updated-by":[{"DOI":"10.1121\/1.410007","type":"correction","label":"Correction","source":"publisher","updated":{"date-parts":[[1994,2,1]],"date-time":"1994-02-01T00:00:00Z","timestamp":760060800000}}],"container-title":["The Journal of the Acoustical Society of America"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/90\/4\/1979\/9431732\/1979_1_online.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/pubs.aip.org\/asa\/jasa\/article-pdf\/90\/4\/1979\/9431732\/1979_1_online.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,3]],"date-time":"2023-08-03T08:15:32Z","timestamp":1691050532000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.aip.org\/jasa\/article\/90\/4\/1979\/963791\/Hearing-loss-in-the-chinchilla-from-impact-and"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1991,10,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[1991,10,1]]}},"URL":"https:\/\/doi.org\/10.1121\/1.401677","relation":{},"ISSN":["0001-4966","1520-8524"],"issn-type":[{"value":"0001-4966","type":"print"},{"value":"1520-8524","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[1991,10]]},"published":{"date-parts":[[1991,10,1]]}}}
