I'm also baffled that there is just zero awareness of the link between loud music and T. Loud music and hearing loss, yes; but I remember blasting music at max volume and thinking "I don't care about hearing loss, at least this noisy world will get a bit quieter." HAHA! The irony!
They should play some T sounds over the school radio for a while and they'd need to bring in fresh garbage bins for all the earphones being thrown away.
