With respect, that's not the point.
This young person does not want to have degraded hearing...period. Some of my old (ex-bomber) captains used to ask me to use the one ear uncovered method. I just could never understand the reason for it. We were on modern jet transport, but the white noise was horrible, and the ‘say agains' to ATC and each other were routine. Just daft.
I think the medical side is one thing, but that this question could perhaps be asked on R&N. In the meantime, do have a full check with an appropriate specialist.
