MCQ
Frequency range of the audible sounds is
- A$0 Hz -30 Hz$
- ✓$20 Hz -20 kHz$
- C$20 kHz -20,000 kHz$
- D$20 kHz -20 MHz$
✓
Answer
Correct option: B.
$20 Hz -20 kHz$
b
(b) The human ear responds to sounds with frequencies in the range from $20 \mathrm{Hz}$ to $20000 \mathrm{Hz}$. This is called the audible range of the human ear.
(b) The human ear responds to sounds with frequencies in the range from $20 \mathrm{Hz}$ to $20000 \mathrm{Hz}$. This is called the audible range of the human ear.
Thus, the frequency range of audible sound is $20 \mathrm{H} z$ to $20000 \mathrm{Hz}$.
