How does the sensitivity of human hearing vary with frequency according to frequency response curves?.
- A.Sensitivity is constant across all frequencies.
- B.Sensitivity decreases at higher frequencies.
- C.Sensitivity varies, with peaks at certain frequencies.
- D.Sensitivity increases with lower frequencies.
Model answer
What a good answer should say
- Sensitivity varies, with peaks at certain frequencies.
Explanation
Why this works
Frequency response curves illustrate that human hearing sensitivity is not uniform; it shows peaks at specific frequencies where the ear is most responsive. This evidence suggests that certain sounds are heard more easily than others, which has implications for sound design and hearing aid technology.
Thus, the conclusion is that understanding these variations is vital for optimizing hearing aids and sound systems.
