Sound Trivia

Permanent hearing loss can result from prolonged exposure to sounds at 85 decibels (0 decibels is the threshold for hearing). For comparison, a busy street corner is about 80 decibels, a subway train heard from 20 feet is 100 decibels, a jet plane heard from 500 feet is 110 decibels, and loud thunder is 120 decibels.
