What is the approximate range of frequencies audible to the normal human ear?
A0 Hz to 200 Hz
B20 Hz to 20000 Hz
C20000 Hz to 40000 Hz
D1 Hz to 20 Hz
Answer & Solution
Correct answer: B. 20 Hz to 20000 Hz
1. Audible waves are those a human ear can detect.
2. This range is from 20 Hz to 20000 Hz.
3. Below 20 Hz is infrasonic and above 20000 Hz is ultrasonic, both inaudible.
