DD is noticeably hard of hearing. She's fine on a one-to-one basis, but struggles to hear if there's several people talking and I have to repeat myself a lot. I'd like to have her hearing investigated, but what is the best way of doing this - do I take her for a hearing test at a high street audiologist to get "proof" of her hearing deficit, or just go straight to the GP and ask for a referral? She's 16 so I think she's too old for the health visitor/school nurse.
