According to this article millions of iPod users are damaging their hearing by listening to music which is louder than a pneumatic drill. Research has found than 1 in 10 people listen to their music at a level which is a higher volume than a drill on a building site. One is six listen at a level which is louder than an aeroplane taking off. According to the article 17% of people have been left with ringing ears after listening to loud music for a long period of time. Damage can start to occur when the ears are exposed to noises louder than 85 decibels for prolonged periods of time. It seems, however, that a quarter of people turn off the volume limiter and 1 in 20 people listen to their music at the highest possible volume with 43% claiming they are not bothered that the loud music might be damaging their hearing. Personally I keep the volume low when listening to music, mainly because I am being considerate of those around me, who I doubt want to hear my music. I do, however, come across many examples where one individual is “delighting” the whole train carriage with the noise from their iPod. I thought the whole point of headphones was so that you can hear your music but no one else can? Perhaps I am missing something.
