To verify the possibility of measuring and discriminating the vibrating pattern of TM, here we describe a micro-vibration measurement method of latex membrane resembling the TM. The measurements are obtained with an externally generated audio stimuli of 2.0, 2.2, 2.8, 3.1 and 3.2 kHz, and their respective vibrations based tomographic, volumetric and quantitative evaluations were acquired using optical Doppler tomography (ODT). The micro oscillations and structural changes which occurred due to diverse frequencies are measured with sufficient accuracy using a highly sensitive ODT system implied phase subtraction method. The obtained results demonstrated the capability of measuring and analyzing the complex varying micro-vibration of the membrane according to implied sound frequency.<\/jats:p>","DOI":"10.3390\/s20010064","type":"journal-article","created":{"date-parts":[[2019,12,23]],"date-time":"2019-12-23T03:15:01Z","timestamp":1577070901000},"page":"64","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["In Situ Characterization of Micro-Vibration in Natural Latex Membrane Resembling Tympanic Membrane Functionally Using Optical Doppler Tomography"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3477-412X","authenticated-orcid":false,"given":"Daewoon","family":"Seong","sequence":"first","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaehwan","family":"Kwon","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1592-6987","authenticated-orcid":false,"given":"Deokmin","family":"Jeon","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ruchire Eranga","family":"Wijesinghe","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, College of Engineering, Kyungil University, Gyeongsan 38428, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaeyul","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3712-5304","authenticated-orcid":false,"given":"Naresh Kumar","family":"Ravichandran","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sangyeob","family":"Han","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junsoo","family":"Lee","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pilun","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Medicine, Institute of Biomedical Engineering, Kyungpook National University, Daegu 41944, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mansik","family":"Jeon","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeehyun","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Electronics Engineering, College of IT engineering, Kyungpook National University, Daegu 41566, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1219","DOI":"10.1016\/j.jbiomech.2010.12.023","article-title":"Biomechanics of the tympanic membrane","volume":"44","author":"Volandri","year":"2011","journal-title":"J.
