A new study suggests that listening to music at more than 80% of maximum volume for more than 90 minutes a day could impair your hearing. The research also indicated that there was no difference in sound levels when looking at different genres, including rock, rap and county. The findings also suggest that ear buds, headphones which are placed in the ears, are no more dangerous then those placed on the outside. Brian Fligor, an audiolostis at the Children’s Hospital of Boston and author of the study, will presented these findings at a conference in Cincinnati. Because ear damage often does not manifest itself for many years, Brian said, “I worry about the teen-ager who’s going to be 23, 24, 25 years old and has a measurable noise-induced hearing loss and now has another 60 something years to live with his hearing which is only going to get worse.
