A 100 dB sound (loud)of 150 Hz (low pitch)would cause which of the following to occur?
A) The tectorial membrane to vibrate slightly near its distal end
B) The tectorial membrane to vibrate vigorously near its proximal end
C) The basilar membrane to vibrate slightly near its proximal end
D) The basilar membrane to vibrate vigorously near its distal end
E) The basilar membrane to vibrate slightly near its distal end

A 100 dB sound is a very loud sound and would cause the basilar membrane to vibrate vigorously, rather than slightly. Additionally, the frequency of the sound is low, which means it would cause the basilar membrane to vibrate more near its distal end (where the membrane is wider and more flexible) rather than near its proximal end. Therefore, the best choice is D.
