The research, conducted by the University of Antwerp and funded by the Royal National Institute for the Deaf -- the charity representing Northern Ireland's 219,000 deaf and hard of hearing people -- found that smoking, being overweight and occupational noise were major risk factors in developing the UK's most common type of hearing loss.
The study found that people who smoke regularly for more than one year had worse hearing than those who had never smoked. . . .
