Nights out 'harm hearing of many'

Nine in 10 young people aged 16-30 experience signs of hearing damage after a night out, research suggests.
The charity RNID found 90% of pub, club and gig-goers experienced dullness of hearing or ringing in the ears after a night on the town.
More than half of the 1,381 surveyed visited a bar where they had to shout to be heard at least once a week.
A quarter said the music in these venues was too loud and a third thought hearing loss would affect their lives. New noise regulations come into force to protect employees in the music and entertainment sectors in April 2008.
But the RNID is calling on the government to establish a recommended noise exposure level for audiences attending music venues and events, and educate young people about noise as a public health risk.
Dr John Low, Chief Executive of RNID, said: "Our research shows most young people have experienced the first signs of permanent hearing damage after a night out, yet have no idea how to prevent it.
"With regular exposure to music at high volumes in clubs, gigs and bars, it's only too easy to clock up noise doses that could damage their hearing forever."
