Or in the ear buds of your i-pod? Rock music 150dB.
New research from Swiss scientists suggests that people living near airports exposed to high levels of noise from air crafts are at increased risk of dying of myocardial infarction. That's an average daily noise level of 60 decibels--and I suspect that's less than what the i-pod user is pumping into his/her ears 24/7. Constant noise. It's not just for deafness.
