By 60 years of age, 60-percent of men and 40-percent of women will snore. But the sound of a snore can seem deafening. While snores average around 60 decibels, the noise level of normal speech, they can reach more than 80 decibels. Eighty decibels is as loud as the sound of a pneumatic drill breaking up concrete. Noise levels over 85 decibels are considered hazardous to the human ear.
