There are a couple of words one can use to refer to someone with a hearing problem, such as "deaf", "hearing-impaired" or "hard of hearing".
I was wondering if we could use the word "problematic" to refer to their disability as in
he can't hear you well, his ears are problematic.
Is it natural to a native speaker to say something like that?
I looked up the word "problematic" in several dictionaries but I couldn't make up my mind:
problematic: causing difficulty, or hard to deal with (Cambridge)
The word seems to be synonymous with "hard", "difficult" and "arduous".
problematic: posing a problem : difficult to solve or decide (Webster)
