Good Audiologist?

I’m being thrown from ENT to ENT since 1.5 yr ago with sudden acute hearing loss on one side. The situation has become very severe and is progressing. I have not actually seen a doctor in all this time outside of getting one mri which came clear. I can’t get neurologist either.

Is there a good audiologist that can take me in quickly just to measure ear pressure? I have not had anyone even do that much from the beginning.

Or do they only sell hearing aids? I wonder if they’re more limited than it says online due to Canadas extremely specialized healthcare system ( many tiers)

Otherwise has anyone had luck going to the US for anything medical related?
