In the mammalian cochlea, wave amplification occurs via the outer hair cells of the organ of Corti. These cells sit directly above a basilar membrane (BM) that has high sensitivity for differences in frequency. Sound waves enter the scala vestibuli of the cochlea and travel throughout it, carrying with them various sound frequencies. These waves exert a pressure on the basilar and tectorial membranes of the cochlea which vibrate in response to sound waves of different frequencies. … http://www.cochlea.eu/en/hair-cells/outer-hair-cells-ohcs rishabh shukla google scholarWebbIt is suitable for audiologists who have no graduate-level qualification in audiology and wish to develop their careers, or academic researchers who have a specialist interest in audiology.
