My high frequency loss above 4KHz are pretty much a goner, so I don’t try to amplify in that range anymore. However, with the Speech Rescue frequency lowering technology, I’m still able to hear sounds in that range well because they got transposed into the 1.5-2.5KHz range for me to hear.
In nature, I can hear sounds like crickets, cicada, etc, that I would never have been able to hear without the frequency lowering technology.
With the OPN, I can hear very subtle things like the echo/reverb in the hall or inside a room with tall ceiling. Normally those are subtle things that you don’t notice and/or take for granted. Or if you don’t hear it then you never even know what you’re missing. Actually, the reason I noticed it the most that one time was when I was trialing the Sonic Enchant 100. It was a nice hearing aid, but kind of quiet and made me feel like being in a coocoon or a sound proofed room. In the same environment, as soon as I switched back to my OPN for A/B comparison on the spot, I immediately noticed that when I talked or sang in the house, I heard the subtle (but noticeable) echo/reverb of my voice.bouncing around the walls and vaulted ceiling in the room.
