Warnings falling on deaf ears
USERS of MP3 players and attenders at rock concerts -- often the same people -- have ignored many warnings, over a long period, about the dangers to their ears. But seldom if ever have the warnings been as grim as they were yesterday, at the beginning of Hearing Awareness Week.
One in five persons listens to sounds with a level of 100 decibels or more, the equivalent of a pneumatic drill 10 feet away. Some MP3 players reach a maximum volume of 115 decibels, the equivalent of a jet plane taking off. Over half of MP3 users listen to players at levels above 89 decibels for up to two hours a day.
These are terrifying statistics, but more shocking are the effects: hearing loss and "ringing in the ears", which can do enormous damage in later life and even in early life.
