The EU's Scientific Committee on emerging health risks, which is normally concerned with noise in factories and the British Parliament, performed a study of MP3 usage. The committee members' findings left them with a strange ringing feeling. They concluded that an hour's iPod usage a day for five years might make as many as 1 in 10 listeners deaf. The problem, the committee believes, is that many people love to listen to their music too loud. In Europe, MP3 players are limited to a mere 100 decibels. However, these European scientists concluded that anything above 89 decibels listened to with regularity has an effect that is louder than the limits imposed on factories
