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.
Operating a lawnmower is approximately 105 decibels, and so on. Anything consistent exposure over 95 decibels should take precautions to protect your hearing, and noises over 140 decibels can cause permanent damage even in short exposure. Anything over ~120 decibels, for example, can cause hearing damage in seconds.
