Two stimulus manipulations were utilized: (1) stimulus onset envelope pressure rate-of-change was held constant while plateau pressure and risetime were varied and (2) plateau duration was varied while plateau pressure and risetime were held constant. When the stimulus onset envelope pressure rate-of-change was held constant, ABR amplitudes increased with risetime and were fit well with an exponential growth model. The model best-fit time constants for ABR peaks P1 and N5 were 55 and 64 \u03bcs, respectively, meaning ABRs reached 99% of their maximal amplitudes for risetimes of 275\u2013320 \u03bcs. When plateau pressure and risetime were constant, ABR amplitudes increased linearly with stimulus sound exposure level up to durations of \u223c250 \u03bcs. The results highlight the relationship between ABR amplitude and the integral of some quantity related to the stimulus pressure envelope over the first \u223c250 \u03bcs following stimulus onset\u2014a time interval consistent with prior estimates of the dolphin auditory temporal window, also known as the \u201ccritical interval\u201d in hearing.<\/jats:p>","DOI":"10.1121\/10.0002703","type":"journal-article","created":{"date-parts":[[2020,11,30]],"date-time":"2020-11-30T15:15:33Z","timestamp":1606749333000},"page":"3360-3371","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":6,"title":["Role of the temporal window in dolphin auditory brainstem response onset"],"prefix":"10.1121","volume":"148","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0969-8033","authenticated-orcid":false,"given":"James J.","family":"Finneran","sequence":"first","affiliation":[{"name":"United States Navy Marine Mammal Program, Naval Information Warfare Center Pacific Code 1 56710, 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 2 , 2240 Shelter Island Drive Number 200, San Diego, California 92106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3795-2083","authenticated-orcid":false,"given":"Madelyn G.","family":"Strahan","sequence":"additional","affiliation":[{"name":"National Marine Mammal Foundation 2 , 2240 Shelter Island Drive Number 200, San Diego, California 92106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0960-8528","authenticated-orcid":false,"given":"Dorian S.","family":"Houser","sequence":"additional","affiliation":[{"name":"National Marine Mammal Foundation 2 , 2240 Shelter Island Drive Number 200, San Diego, California 92106, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert F.","family":"Burkard","sequence":"additional","affiliation":[{"name":"Department of Rehabilitation Science, University at Buffalo 3 , 626 Kimball Tower, Buffalo, New York 14214, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"231","published-online":{"date-parts":[[2020,11,30]]},"reference":[{"key":"2023071803260688500_c1","first-page":"47","volume-title":"Acoustical Terminology","author":"ANSI","year":"1994"},{"key":"2023071803260688500_c2","first-page":"28","volume-title":"Procedure for Determining Audiograms in Toothed Whales through Evoked Potential Methods","author":"ANSI","year":"2018"},{"first-page":"227","volume-title":"The Sonar of Dolphins","year":"1993","key":"2023071803260688500_c3"},{"key":"2023071803260688500_c4","doi-asserted-by":"publisher","first-page":"1585","DOI":"10.1121\/1.382884","article-title":"Digital equalization of underwater transducers for the projection of broadband acoustic signals","volume":"65","year":"1979","journal-title":"J.
