To demonstrate that emission generators distributed basal to the f2 primary-tone contribute, in general, to DPOAE levels and phases, a high-frequency interference tone (IT) was presented at 1\/3 of an octave (oct) above the f2 primary-tone, and DPOAEs were re-measured as \u201caugmented\u201d DP-grams (ADP-grams) and L\/P maps. The vector difference between the control and augmented functions was then computed to derive residual DP-grams (RDP-grams) and L\/P maps. The resulting RDP-grams and L\/P maps, which described the DPOAEs removed by the IT, supported the notion that basal DPOAE components routinely contribute to the generation of standard measures of DPOAEs. Separate experiments demonstrated that these components could not be attributed to the effects of the 1\/3-oct IT on f2, or DPOAEs generated by the addition of a third interfering tone. These basal components can \u201cfill in\u201d the lesion estimated by the commonly employed DP-gram. Thus, ADP-grams more accurately reveal the pattern of cochlear damage and may eventually lead to an improved DP-gram procedure.<\/jats:p>","DOI":"10.1121\/1.3353121","type":"journal-article","created":{"date-parts":[[2010,5,13]],"date-time":"2010-05-13T21:47:47Z","timestamp":1273787267000},"page":"2955-2972","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":48,"title":["Evidence for basal distortion-product otoacoustic emission components"],"prefix":"10.1121","volume":"127","author":[{"given":"Glen K.","family":"Martin","sequence":"first","affiliation":[{"name":"VA Loma Linda Healthcare System Research Service, and Department of Otolaryngology\u2013Head and Neck Surgery, , Loma Linda, California 92357"},{"name":"Loma Linda University Medical Center Research Service, and Department of Otolaryngology\u2013Head and Neck Surgery, , Loma Linda, California 92357"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Barden B.","family":"Stagner","sequence":"additional","affiliation":[{"name":"VA Loma Linda Healthcare System Research Service, and Department of Otolaryngology\u2013Head and Neck Surgery, , Loma Linda, California 92357"},{"name":"Loma Linda University Medical Center Research Service, and Department of Otolaryngology\u2013Head and Neck Surgery, , Loma Linda, California 92357"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brenda L.","family":"Lonsbury-Martin","sequence":"additional","affiliation":[{"name":"VA Loma Linda Healthcare System Research Service, and Department of Otolaryngology\u2013Head and Neck Surgery, , Loma Linda, California 92357"},{"name":"Loma Linda University Medical Center Research Service, and Department of Otolaryngology\u2013Head and Neck Surgery, , Loma Linda, California 92357"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2010,5,12]]},"reference":[{"key":"2023072522442874900_c1","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1001\/archotol.125.2.215","article-title":"High-frequency hearing influences lower-frequency acoustic distortion products","volume":"125","year":"1999","journal-title":"Arch.
