An NHL playoff game has an average decibel level of 105 dB. To protect one's hearing, specialists recommend that children where ear muffs to playoff games to reduce the loudness by 30 dB. The formula dB = 10 log I where dB is the loudness of sound, in decibels and the is the sound intensity. Determine how many more times intense it would be for a child when not wearing ear muffs compared to wearing ear muffs, at the same NHL playoff game.
