The offset ABR has not been extensively investigated in marine mammals. Three normal hearing (NH) and three hearing impaired (HI) dolphins were assessed while fully submerged in sea water. Stimulus spectrum, level, rise\/fall time (RFT), and plateau duration were manipulated. Onset and offset ABR amplitude were quantified as the rms voltage 1\u20137 ms following stimulus onset or offset, respectively. For the same stimulus conditions, onset and offset responses were often larger for NH than HI dolphins, and offset responses were typically smaller than onset responses. For the level series, offset response amplitude typically increased with increasing stimulus level, although offset responses were not 3 dB above the noisefloor for 113-kHz tonebursts. Increasing RFT decreased onset and offset response amplitude. For the 40-kHz tonebursts, a RFT of 32 \u03bcs produced a large amplitude offset ABR in NH dolphins. Offset responses for 113-kHz tonebursts were 3 dB above the noisefloor at the shortest RFTs. Offset responses were largest for 4 ms duration stimuli (likely due to overlapping onset and offset response analysis windows), but otherwise, offset responses changed little with increasing duration.<\/jats:p>","DOI":"10.1121\/10.0001900","type":"journal-article","created":{"date-parts":[[2020,9,15]],"date-time":"2020-09-15T13:58:32Z","timestamp":1600178312000},"page":"1445-1455","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Offset auditory brainstem response (ABR) amplitude in bottlenose dolphins"],"prefix":"10.1121","volume":"148","author":[{"given":"Robert","family":"Burkard","sequence":"first","affiliation":[{"name":"Department of Rehabilitation Science, University at Buffalo 1 , 626 Kimball Tower, Buffalo, New York 14260, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0969-8033","authenticated-orcid":false,"given":"James J.","family":"Finneran","sequence":"additional","affiliation":[{"name":"U.S. Navy Marine Mammal Program, Naval Information Warfare Center Pacific Code 56710 2 , 53560 Hull Street, San Diego, California 92152, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jason","family":"Mulsow","sequence":"additional","affiliation":[{"name":"National Marine Mammal Foundation 3 , 2240 Shelter Island Drive #200, San Diego, California 92106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryan","family":"Jones","sequence":"additional","affiliation":[{"name":"National Marine Mammal Foundation 3 , 2240 Shelter Island Drive #200, San Diego, California 92106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2020,9,15]]},"reference":[{"key":"2023073120412056000_c1","doi-asserted-by":"publisher","first-page":"225","DOI":"10.3109\/00206099309072938","article-title":"Effects of noise burst rise time and level on the human brainstem auditory evoked response","volume":"32","year":"1993","journal-title":"Audiology"},{"key":"2023073120412056000_c2","doi-asserted-by":"publisher","first-page":"27","DOI":"10.3109\/01050397909076298","article-title":"Human auditory on- and off-potentials of the brainstem: Influence of stimulus envelope characteristics","volume":"8","year":"1979","journal-title":"Scand.
