I assume your ears are free of wax? Something as simple as earwax can have a massive effect and if you’ve had it for a long time you might not even notice it. I’m no expert, but you say you’ve had a hearing test, but those who test hearing sometimes aren’t medical professionals so won’t necessarily give you the root course of the issue? I’d like to think the NHS one would have flagged something as simple as earwax but just putting it out there.I have had a couple of hearing tests recently. One at boots and another through the NHS. I cant remember the exact results but i think i'l be ok with the lower frequencies. The 2 kHz was the worst and i was given the option to try hearing aids, but it was my choice. The fact that I was offered the choice suggested to me that its not as bad as it could be but at the same time, why offer them in the first place.
I personally feel like I can hear all around me. I can make a conversation on the phone and hear all alarms and warnings that i need to hear. I just hope thats going to be enough.
