At which location along the basilar membrane are the highest-frequency sounds detected?
Nearest the oval window
Fahest from the oval window, near the helicotrema
Uniformly along the basilar membrane
At the midpoint of the membrane
The basilar membraneis widest (0.42-0.65 mm) and least stiff at the apex of the cochlea, and narrowest (0.08-0.16 mm) and stiffest at the base (near the round and oval windows). High-frequency soundslocalize near the base of the cochlea, while low-frequency sounds localize near the apex. Ref otolaryngology dhingra 3/e p34
