What is the primary reason that hearing sensitivity varies with frequency?.
Model answer
What a good answer should say
- Hearing sensitivity varies with frequency primarily due to the structure of the cochlea, which has hair cells that respond differently to various frequencies of sound.
- This variation in response leads to certain frequencies being perceived more acutely than others, affecting overall hearing ability.
Explanation
Why this works
This answer is strong because it identifies the cochlea's structure as the cause and explains how it affects sensitivity to different frequencies, linking the mechanism to the effect on hearing ability. The consequence is a variation in perceived sound quality across frequencies.
