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.
For example, usual conversation is approximately 60 decibels, the humming of a refrigerator is 40 decibels and city traffic noise can be 80 decibels. Examples of sources of loud noises that cause NIHL are motorcycles, firecrackers and small arms fire, all emitting sounds from 120 decibels to 140 decibels.
