Solution :-
The intensity of sound at a calm place should be 0 dB.
The decibel (abbreviated dB) is the unit to measure the intensity of sound. The decibel scale is a little odd because the human ear is incredibly sensitive. Human ear can hear everything from our fingertip brushing lightly over our skin to a loud jet engine. In terms of power, the sound of the jet engine is about 1,000,000,000,000 times more powerful than the smallest audible sound. That's a big difference.
On the decibel scale,the smallest audible sound (near total sound) is 0 dB. A sound 10 times more powerful is 10 dB. A sound 100 times more powerful than near total silence is 20 dB. A sound 1000 times more powerful than near total silence is 30 dB.
