I just wanted to post my experience with getting a Class 1 medical as someone with a hearing impairment.
I initially had much difficulty with this from the CAA as (at least back then) the requirements for initial applicants and those renewing/revalidating their medicals are slightly different. My situation is that I wear two bone-anchored hearing aids, and that is practically where all my hearing ability comes from. My hearing is excellent in reality, but I use a slightly adapted setup in an aircraft to manage listening to air traffic control. As a result, the CAA didn't want to consider me as their only view on the matter was meeting the audiogram requirements, which I didn't. But as others here have mentioned, you can do a Functional Hearing Assessment which should enable you to get the medical.
I have had a few people contact me experiencing difficulties with this on some levels with other national regulatory bodies – but it is possible! My main advice as someone who spent five years arguing my case is to keep trying!
I have an article on LinkedIn explaining my experience in more depth if anyone wants to read it. It is slightly outdated, however, as I have gained my PPL since writing and hope to try for a place on a cadet programme.
