The goal was to find emission parameters and measures that best differentiated between the two dysfunctions, e.g., at a given ABR threshold elevation. Emission input\u2013output or \u201cgrowth\u201d functions were used (frequencies f1 and f2,\u2008f2\/f1=1.21) with equal levels, L1=L2, and unequal levels, with L1=L2+20\u2009dB. The best parametric choice was found to be unequal stimulus levels, and the best measure was found to be the change in the emission threshold level, \u0394x. The emission threshold was defined as the stimulus level required to reach a criterion emission amplitude, in this case \u221210 dB SPL. (The next best measure was the change in emission amplitude at high stimulus levels, specifically that measured at L1\u00d7L2=90\u00d770\u2009dB SPL.) For an ABR threshold shift of 20 dB or more, there was essentially no overlap in the emission threshold measures for the two conditions, sound damage or furosemide. The dividing line between the two distributions increased slowly with the change in ABR threshold, \u0394ABR, and was given by \u0394xt=0.6\u2008\u0394ABR+8\u2009dB. For a given \u0394ABR, if the shift in emission threshold was more than the calculated dividing line value, \u0394xt, the auditory dysfunction was due to acoustic damage, if less, it was due to furosemide.<\/jats:p>","DOI":"10.1121\/1.1535942","type":"journal-article","created":{"date-parts":[[2003,1,30]],"date-time":"2003-01-30T20:35:59Z","timestamp":1043958959000},"page":"914-924","update-policy":"http:\/\/dx.doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":29,"title":["Differential responses to acoustic damage and furosemide in auditory brainstem and otoacoustic emission measures"],"prefix":"10.1121","volume":"113","author":[{"given":"David M.","family":"Mills","sequence":"first","affiliation":[{"name":"V.
