Pulsed DPOAE level maps (LMs), which allow the derivation of estimated distortion-product thresholds (L2,EDPT), address some of these limitations. However, their reliability may still be compromised by standing-wave phenomena and calibration errors. In this study, we systematically compared four calibration methods\u2014standard sound-pressure level (SPL), forward pressure level (FPL), integrated pressure level (IPL), and the combined methods of IPL and emitted pressure level (EPL), denoted as IPL+EPL\u2014on LMs in eleven subjects across two sessions with intentionally varied probe insertion depths. Both FPL and IPL significantly reduced the intersession variability of LM-parameters compared with SPL, while IPL performed consistently better. The IPL+EPL calibration demonstrated additional benefits in reducing standing-wave effects on DPOAE and derived quantities. The analysis of three parameters describing the dependence of DPOAE on the two primary levels L2 and L1, confirmed that calibration-dependent changes in LM parameters could be interpreted as conduction loss (or gain) specifically for the frequencies f1, f2, and fDP. Advanced calibration methods, particularly IPL, substantially improve the reliability of LMs and enhance their potential for clinical audiometric applications.<\/jats:p>","DOI":"10.1121\/10.0043953","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T11:56:16Z","timestamp":1781783776000},"page":"5504-5526","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Influences of stimulus and response calibrations on level maps of pulsed distortion-product otoacoustic emissions"],"prefix":"10.1121","volume":"159","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-4108-9722","authenticated-orcid":false,"given":"Stephan","family":"Kempa","sequence":"first","affiliation":[{"name":"Section of Physiological Acoustics and Communication, Department of Otolaryngology - Head and Neck Surgery 1 , , T\u00fcbingen,","place":["Germany"]},{"name":"Eberhard Karls University of T\u00fcbingen 1 , , T\u00fcbingen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Philipp","family":"Graff","sequence":"additional","affiliation":[{"name":"Section of Physiological Acoustics and Communication, Department of Otolaryngology - Head and Neck Surgery 1 , , T\u00fcbingen,","place":["Germany"]},{"name":"Eberhard Karls University of T\u00fcbingen 1 , , T\u00fcbingen,","place":["Germany"]},{"name":"Chair of Thermodynamics, TUM School of Engineering and Design 2 , , M\u00fcnchen,","place":["Germany"]},{"name":"Technical University of Munich 2 , , M\u00fcnchen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4937-9130","authenticated-orcid":false,"given":"Anthony W.","family":"Gummer","sequence":"additional","affiliation":[{"name":"Section of Physiological Acoustics and Communication, Department of Otolaryngology - Head and Neck Surgery 1 , , T\u00fcbingen,","place":["Germany"]},{"name":"Eberhard Karls University of T\u00fcbingen 1 , , T\u00fcbingen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ernst","family":"Dalhoff","sequence":"additional","affiliation":[{"name":"Section of Physiological Acoustics and Communication, Department of Otolaryngology - Head and Neck Surgery 1 , , T\u00fcbingen,","place":["Germany"]},{"name":"Eberhard Karls University of T\u00fcbingen 1 , , T\u00fcbingen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0599-1304","authenticated-orcid":false,"given":"Katharina","family":"Bader","sequence":"additional","affiliation":[{"name":"Section of Physiological Acoustics and Communication, Department of Otolaryngology - Head and Neck Surgery 1 , , T\u00fcbingen,","place":["Germany"]},{"name":"Eberhard Karls University of T\u00fcbingen 1 , , T\u00fcbingen,","place":["Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2026,6,18]]},"reference":[{"key":"2026061807561120600_c1","doi-asserted-by":"publisher","first-page":"812","DOI":"10.1121\/1.4996859","article-title":"Towards a joint reflection-distortion otoacoustic emission profile: Results in normal and impaired ears","volume":"142","year":"2017","journal-title":"J.
