My mother has poor hearing and she refuses to get a hearing aid mainly due to cost. They are ~$4K per ear she doesn't have the money but to her an elderly person she imagines it as $40K/ear. I also fear dementia has already begun for her. For me I have tinnitus so this drug would also be welcome.
Another interesting drug is Vuity for nearsightedness. Between hearing and sight it will be amazing if such drugs work and were available before my mother or I or anyone dies of old age.
