I'm not sure there is one, I was going to suggest 'hearing imparied', however, I googled it and found this on wikipedia.
'When applied to humans, the term hearing impaired is rejected by the deaf culture movement, where the terms deaf and hard-of-hearing are preferred.'
'The term hearing impaired is more likely to be used by people with a less than severe hearing loss and people who have acquired deafness in adulthood than by those who have grown up deaf. By contrast, those who identify with the Deaf culture movement typically reject the label impaired and other labels that imply that deafness is a pathological condition, viewing it instead as a locus of pride.'
I'm afraid I can't help you any more than that, sorry.
