This species is also exceptional for its ability to modify its middle ear tuning by closing the Eustachian tubes (ET). Using scanning laser Doppler vibrometry, the tympanal vibrations were measured to investigate if the tuning shift caused by the ET closure contributes to intraspecific acoustic communication. To gain insight into the inner ear frequency selectivity and sensitivity of this species, distortion product otoacoustic emissions were recorded at multiple frequency-level combinations. Our measurements of inner ear responses indicated that in <jats:italic>O. tormota<\/jats:italic> each sex is more sensitive to the frequencies of the other sex's vocalizations, female ears are more sensitive to 2\u20137\u00a0kHz, while male ears are more sensitive to 3\u201315\u00a0kHz. We also found that in both sexes the ET closure impacts the sensitivity of the middle and inner ear at frequencies used for communication with conspecifics. This study broadens our understanding of peripheral auditory mechanisms contributing to intraspecific acoustic communication in anurans.<\/jats:p>","DOI":"10.1007\/s00359-022-01569-8","type":"journal-article","created":{"date-parts":[[2022,9,15]],"date-time":"2022-09-15T03:30:25Z","timestamp":1663212625000},"page":"79-88","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["DPOAEs and tympanal membrane vibrations reveal adaptations of the sexually dimorphic ear of the concave-eared torrent frog, Odorrana tormota"],"prefix":"10.1007","volume":"209","author":[{"given":"Ariadna","family":"Cobo-Cuan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Albert S.","family":"Feng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter M.","family":"Narins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,9,15]]},"reference":[{"issue":"7","key":"1569_CR1","doi-asserted-by":"publisher","first-page":"665","DOI":"10.1007\/s00359-008-0338-y","volume":"194","author":"C Bergevin","year":"2008","unstructured":"Bergevin C, Freeman DM, Saunders JC, Shera CA (2008) Otoacoustic emissions in humans, birds, lizards, and frogs: evidence for multiple generation mechanisms.
