Which range of frequencies can a healthy human ear detect?
A2 Hz to 2 000 Hz
B200 Hz to 2 000 Hz
C20 Hz to 200 000 Hz
D20 Hz to 20 000 Hz
Answer & Solution
Correct answer: D. 20 Hz to 20 000 Hz
1. The ear does not respond to every frequency of pressure wave.
2. Frequencies from 20 to 20 000 hertz are audible to the human ear.
3. Below that band the sound is called infrasound and cannot be heard.
4. Above that band the sound is called ultrasound, which some animals hear but people do not.
