At present, it is known that during an acoustic stimulation a travelling wave is developed inside the cochlea. Existing mathematical and numerical models available in the literature try to describe the shape of this travelling wave, the majority of them present a set of approaches based on some limitations either or both of the mechanical properties used and the geometrical description of the realistic representation. The present numerical study highlights the distinctions of using a spiral model of the cochlea, by comparing the obtained results with a straight, or simplified model. The influence of the implantation of transversely isotropic mechanical models was also studied, by comparing the basilar membrane with isotropic and transversely isotropic mechanical properties. Values of the root mean square error calculated for all models show a greater proximity of the cochlear mapping to the Greenwood function when the basilar membrane is assumed with transversely isotropic mechanical properties for both straight and spiral model. The root-mean square errors calculated were: 2.05, 1.70, 2.72, 2.08\u2009mm, for the straight-isotropic, straight-transversely isotropic, spiral-isotropic and spiral-transversely isotropic model, respectively. <\/jats:p>","DOI":"10.1177\/09544119211003443","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T05:53:55Z","timestamp":1616392435000},"page":"743-750","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":6,"title":["Influence of the basilar membrane shape and mechanical properties in the cochlear response: A numerical study"],"prefix":"10.1177","volume":"235","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9583-3571","authenticated-orcid":false,"given":"Bruno","family":"Areias","sequence":"first","affiliation":[{"name":"INEGI, Institute of Science and Innovation in Mechanical and Industrial Engineering, Porto, Portugal"}]},{"given":"Marco","family":"Parente","sequence":"additional","affiliation":[{"name":"INEGI, Institute of Science and Innovation in Mechanical and Industrial Engineering, Porto, Portugal"},{"name":"FEUP, Faculty of Engineering, University of Porto, Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6521-3475","authenticated-orcid":false,"given":"Fernanda","family":"Gentil","sequence":"additional","affiliation":[{"name":"Escola Superior de Sa\u00fade, Cl\u00ednica ORL \u2013 Dr. Eurico de Almeida, WIDEX, Porto, Portugal"}]},{"given":"Renato Natal","family":"Jorge","sequence":"additional","affiliation":[{"name":"INEGI, Institute of Science and Innovation in Mechanical and Industrial Engineering, Porto, Portugal"},{"name":"FEUP, Faculty of Engineering, University of Porto, Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2021,3,21]]},"reference":[{"key":"bibr1-09544119211003443","unstructured":"WHO.
