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.
Anything in the range of 140 decibels, like a jet engine, is an immediate danger to your hearing. Exposure could create acoustic trama resulting in immediate deafness. Around 125 decibels, roughly as loud as a firecracker, is refered to as the pain threshold. It's the point where your ear interpert the level of sound as physically painful. Prolonged exposure at this level is very dangerous. The average rock concert is 120 decibels. At that volume hearing damage occurs in 7.5 minutes.
