Ah, PTA calculation is an error.
Agree with Um Bongo.
Interesting stuff. I am correct in interpretting that you have had this difficulty for as long as you can remember? Did your audiologist do any speech in noise testing? I’ve had adult patients with undiagnosed CAPD (not unreasonable given that testing wasn’t widespread until recently) for whom hearing aids aren’t enough and an FM system was more useful.
CAPD testing might be interesting, but unless you need a diagnosis to access services (like we do for school children) or for personal peace of mind or to educate family members, you can probably skip the testing and go straight to trialing devices. My experience is that an ENT would not be very useful in this, although if this has only become a problem recently (rather than for as long as you can remember) it might be a good idea to see some other specialists.
Do you have difficulty reading, too?
