Two ATF tests were designed using an improved calibration method over a frequency range (0.25\u20138 kHz): an ambient-pressure test and a tympanometric test using an excess static pressure in the ear canal. Wideband responses were objectively classified using moment analyses of energy transmittance, which was a more appropriate test variable than energy reflectance. Subjects included adults and children of age 10 years and up, with 42 normal-functioning ears and 18 ears with a conductive hearing loss. Predictors were based on the magnitudes of the moment deviations from the 10th to 90th percentiles of the normal group. Comparing tests at a fixed specificity of 0.90, the sensitivities were 0.28 for peak-compensated static acoustic admittance at 226 Hz, 0.72 for ambient-pressure ATF, and 0.94 for pressurized ATF. Pressurized ATF was accurate at predicting conductive hearing loss with an area under the receiver operating characteristic curve of 0.95. Ambient-pressure ATF may have sufficient accuracy to use in some hearing-screening applications, whereas pressurized ATF has additional accuracy that may be appropriate for hearing-diagnostic applications.<\/jats:p>","DOI":"10.1121\/1.1625931","type":"journal-article","created":{"date-parts":[[2003,12,12]],"date-time":"2003-12-12T16:27:42Z","timestamp":1071246462000},"page":"3217-3238","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":105,"title":["Energy transmittance predicts conductive hearing loss in older children and adults"],"prefix":"10.1121","volume":"114","author":[{"given":"Douglas H.","family":"Keefe","sequence":"first","affiliation":[{"name":"Boys Town National Research Hospital, 555 North 30th Street, Omaha, Nebraska\u200968131"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeffrey L.","family":"Simmons","sequence":"additional","affiliation":[{"name":"Boys Town National Research Hospital, 555 North 30th Street, Omaha, Nebraska\u200968131"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2003,12,2]]},"reference":[{"key":"2023071404065461600_agu95","doi-asserted-by":"crossref","first-page":"1950","DOI":"10.1121\/1.412068","article-title":"Time-domain deconvolution to measure reflection functions from discontinuities in waveguides","volume":"97","year":"1995","journal-title":"J.
