Question

We can hear the sound of frequency in the range of ______.

Answer 1

1. All vibrations cause sound.
2. But human ears can't hear all frequencies of sound.
3. We can hear sounds of frequencies in the range from $20Hzto20000Hz$.
4. We cannot hear sounds with frequencies below $20Hz$ and above frequency $20000Hz$.
5. And this range of frequency is called the audible range.

Hence, We can hear the sound of frequency in the range of $20Hzto20000Hz.$
