Here, we report measurements of cochlear function from guinea pigs when the cochlea was stimulated at acoustic frequencies by movements of a miniature magnet which partially occluded the RW. Maximum cochlear sensitivity, corresponding to subnanometre magnet displacements at neural thresholds, was observed for frequencies around 20 kHz, which is similar to that for acoustic stimulation. Neural response latencies to acoustic and RW stimulation were similar and taken to indicate that both means of stimulation resulted in the generation of conventional travelling waves along the cochlear partition. It was concluded that the relatively high impedance of the ossicles, as seen from the cochlea, enabled the region of the RW not occluded by the magnet, to act as a pressure shunt during RW stimulation. We propose that travelling waves, similar to those owing to acoustic far-field pressure changes, are driven by a jet-like, near-field component of a complex pressure field, which is generated by the magnetically vibrated RW. Outcomes of research described here are theoretical and practical design principles for the development of new types of hearing aids, which use near-field, RW excitation of the cochlea.<\/jats:p>","DOI":"10.1098\/rsif.2013.1120","type":"journal-article","created":{"date-parts":[[2014,2,5]],"date-time":"2014-02-05T10:24:47Z","timestamp":1391595887000},"page":"20131120","update-policy":"http:\/\/dx.doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["A novel mechanism of cochlear excitation during simultaneous stimulation and pressure relief through the round window"],"prefix":"10.1098","volume":"11","author":[{"given":"Thomas D.","family":"Weddell","sequence":"first","affiliation":[{"name":"School of Pharmacy and Biomolecular Sciences, University of Brighton, Brighton BN2 4GJ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yury M.","family":"Yarin","sequence":"additional","affiliation":[{"name":"Clinic of Otorhinolaryngology, Department of Medicine, Universit\u00e4tsklinikum Dresden, Fetscherstrasse 74, Dresden 01307, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Markus","family":"Drexl","sequence":"additional","affiliation":[{"name":"German Vertigo Center, Ludwig-Maximilians University Munich, Marchioninistrasse 15, Munich 81377, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ian J.","family":"Russell","sequence":"additional","affiliation":[{"name":"School of Pharmacy and Biomolecular Sciences, University of Brighton, Brighton BN2 4GJ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen J.","family":"Elliott","sequence":"additional","affiliation":[{"name":"Institute of Sound and Vibration Research, University of Southampton, Southampton SO17 1BJ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrei N.","family":"Lukashkin","sequence":"additional","affiliation":[{"name":"School of Pharmacy and Biomolecular Sciences, University of Brighton, Brighton BN2 4GJ, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"175","published-online":{"date-parts":[[2014,4,6]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1152\/ajplegacy.1935.111.2.416"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348940211100907"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200303000-00021"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-007-0305-1"},{"key":"e_1_3_3_6_2","first-page":"11","article-title":"Surgical aspects of cochlear implantation: mechanisms of insertional trauma","volume":"64","author":"Roland PS","year":"2006","journal-title":"Adv.
