Hearing Loss, ETD, or Something Else?

Hi all.

I have been having hearing loss since feb of this year. It was sudden and kinda over night. Fast forward to now and it's still there. My doctor and ENT said its Eustachian Tube.

My hearing in my left is far more bassey then right.If I listen to something with bass and put my head sideways, it's like the bass goes straight to my left ear. Could this be ETD?

I have no problem hearing things in general it's sounds that are more bass driven are very annoying to me. Like car engines are really boomy sounding in one ear.

Any advice? I must add I have nasal polyps so could be this?

 

Did you have an audiogram?
