Intracochlear distortion products are broadly generated by outer hair cells but their contributions to otoacoustic emissions are spatially restricted

T Bowling, H Wen, SWF Meenderink, W Dong… - Scientific Reports, 2021 - nature.com
Detection of low-level sounds by the mammalian cochlea requires electromechanical
feedback from outer hair cells (OHCs). This feedback arises due to the electromotile …

Link between stimulus otoacoustic emissions fine structure peaks and standing wave resonances in a cochlear model

H Wen, J Meaud - The Journal of the Acoustical Society of America, 2022 - pubs.aip.org
In response to an external stimulus, the cochlea emits sounds, called stimulus frequency
otoacoustic emissions (SFOAEs), at the stimulus frequency. In this article, a three …

Understanding the micromechanics of the cochlea

R Marrocchio - 2022 - eprints.soton.ac.uk
The function of the cochlea is to convert the sound waves that reach our ears into neural
signals that can be interpreted by the brain. Its mechanics can be modelled as two fluid …
