Pressure travels through the cochlea via fluid displacement of the basilar membrane
Pressure waves travel through the fluid-filled cochlea, creating traveling waves that displace the basilar membrane.
The claim describes the fundamental mechanism of cochlear mechanics, where acoustic pressure creates fluid waves (perilymph/endolymph) that propagate through the cochlea and cause mechanical displacement of the basilar membrane. Papers 5, 7, and 11 explicitly detail this fluid-structure interaction and energy transfer from cochlear fluid to basilar membrane displacement.
