I have blogged about this issue several times before, but it’s always good to be reminded. BBC Health reports:

One in 10 people with personal MP3 or CD players could suffer permanent hearing loss because their music is too loud, according to an EU study.
Scientists say those who listen at high volume for more than one hour per day over five years risk permanent harm.
They say up to 10 million people across Europe, including many children and adolescents, could be affected.
The European Commission will now look into whether technical improvements could minimise hearing damage.
