Question

Chronic exposure to extremely loud low-pitched noises (> 150 dB) are likely to destroy hair cells at (the) _______ of the cochlea.

Quizplus · Accepted Answer

The apex of the cochlea is more sensitive to low-pitched (low-frequency) sounds, while the base is more sensitive to high-pitched (high-frequency) sounds. Chronic exposure to extremely loud, low-pitched noises would therefore more likely damage hair cells at the apex of the cochlea.
