A tone caused by striking one of the lowest notes on a piano keyboard will cause vibration of the basilar membrane at a point closer to the helicotrema than to the oval window.

Question

Quizplus · Accepted Answer

This statement is true. The basilar membrane is a long, narrow membrane in the cochlea of the inner ear that vibrates in response to sound waves. The membrane is thicker and stiffer near the oval window and thinner and more flexible near the helicotrema. Lower frequency sounds, such as those produced by the lowest notes on a piano keyboard, will cause vibration of the basilar membrane at a point closer to the helicotrema than to the oval window.
