Answers. Best Answer: Up to about 120 decibels, which is about as loud as a gunshot. Some of the factors that affect the loudness are energy released, the environment, and of course the distance you are from the lightning.
The decibel (abbreviated dB) is the unit used to measure the intensity of a sound. The decibel scale is a little odd because the human ear is incredibly sensitive. Your ears can hear everything from your fingertip brushing lightly over your 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.
