I can only hear things if there's no background noise. does a hearing aid sound like it'd be a good fit for me?

Discriminatory loss: In forms of hearing that effect the nerves rather than the bones in the ear, there is what is called discriminatory hearing loss, which is what you have. Hearing aides amplify sounds, and that often is not helpful. However, newer technology can reduce or even eliminate a lot of background noises. Talk to an audiologist or an ENT specialist who can recommend appropriate testing and treatment.
