摘要：The cochlear frequency-place map is believed to be animportant determinant of the frequencies that a species can hearas well as the bandwidth of cochlear filters. Both features impactan animal's ability to detect biologically significant sounds innoise. The cochlear frequency-place map is created partially astiffness gradient in the basilar membrane (BM) in which stiffregions respond best to high frequencies and more compliantregions respond best to low frequencies.BM mass doesn’t playsignificant role infrequency –place map as it remains constant,Due to the position of BM in cochlea, the BM stiffnessmeasurements are difficult. Both hemi cochlea and ipreparations are carried out worldwide for BM stiffnessmeasurements along longitudinal length and radial length. Bothmethods can be specific for different species and utmost care isexercised to maintain the integrity of the tissues underconsideration.BM mechanical properties can change during itsearly developmental stage gets matured in adult and degradeagain due to aging, exhibiting change infrequencyAlso BM exhibits longitudinal coupling which make complexenergy transfers in cochlear duct during wave propagation.BMmechanical properties, its measurement techniques are presentedin this paper. Alteration in BM mechanics by any factor may leadto hearing impairments
