After being damaged by the explosion impact wave, it usually causes long-term deafness, tinnitus, and other symptoms. To better understand the influence of impact load on the cochlea and basilar membrane (BM), a three-dimensional (3D) fluid-solid coupling finite element model was developed. This model accurately reflects the actual spatial spiral shape of the human cochlea, as well as the lymph environment and biological materials. Based on verifying the reliability of the model, the curve of impact load-amplitude response was obtained, and damage of impact load on the cochlea and the key macrostructure-BM was analyzed. The results indicate that impact wave at middle frequency has widest influence on the cochlea. Furthermore, impact loading causes tears in the BM and destroys the cochlear frequency selectivity.<\/jats:p>","DOI":"10.1177\/09544119231209187","type":"journal-article","created":{"date-parts":[[2023,11,13]],"date-time":"2023-11-13T06:09:18Z","timestamp":1699855758000},"page":"1390-1399","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Study on damage of the macrostructure of the cochlea under the impact load"],"prefix":"10.1177","volume":"237","author":[{"given":"Jiakun","family":"Wang","sequence":"first","affiliation":[{"name":"School of Mechanics and Engineering Science, Shanghai University, Shanghai, China"},{"name":"Shanghai Institute of Applied Mathematics and Mechanics, Shanghai University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junyi","family":"Liang","sequence":"additional","affiliation":[{"name":"Genomic Medicine Institute, Lerner Research Institute, Cleveland Clinic Foundation, Cleveland, OH, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Gao","sequence":"additional","affiliation":[{"name":"School of Mechanics and Engineering Science, Shanghai University, Shanghai, China"},{"name":"Shanghai Institute of Applied Mathematics and Mechanics, Shanghai University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5627-2775","authenticated-orcid":false,"given":"Wenjuan","family":"Yao","sequence":"additional","affiliation":[{"name":"School of Mechanics and Engineering Science, Shanghai University, Shanghai, China"},{"name":"Shanghai Institute of Applied Mathematics and Mechanics, Shanghai University, Shanghai, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2023,11,13]]},"reference":[{"key":"bibr1-09544119231209187","volume-title":"Deafness and hearing impairment","author":"World Health Organization","year":"2015"},{"key":"bibr2-09544119231209187","volume-title":"Experiments in hearing","author":"B\u00e9k\u00e9sy GV","year":"1960"},{"key":"bibr3-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1121\/1.405716"},{"key":"bibr4-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.96.7.3676"},{"key":"bibr5-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1016\/0025-5564(71)90023-X"},{"key":"bibr6-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1016\/0025-5564(74)90023-6"},{"key":"bibr7-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1142\/S0219519414500614"},{"key":"bibr8-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1007\/s10439-007-9366-y"},{"key":"bibr9-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2011.2159714"},{"key":"bibr10-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1016\/j.compbiomed.2021.104756"},{"key":"bibr11-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1142\/S0219519414500511"},{"key":"bibr12-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2018.1497304"},{"key":"bibr13-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1007\/s10483-017-2211-6"},{"key":"bibr14-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1115\/1.4046204"},{"key":"bibr15-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1016\/j.cnsns.2021.106043"},{"key":"bibr16-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1016\/S0378-5955(98)00133-6"},{"key":"bibr17-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1121\/1.1575750"},{"key":"bibr18-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1177\/09544119211003443"},{"key":"bibr19-09544119231209187","doi-asserted-by":"publisher","DOI":"10.1002\/cnm.3541"},{"key":"bibr20-09544119231209187","unstructured":"Chen W.
