Has anyone with severe hearing loss transitioned from NAL NL-2 or Adaptive Phonak Digital to DSL v5.0a?

This past August, I suffered further loss of hearing in my left ear (Audiogram updated). The right ear is the same.

Television audio sounds a bit clearer, plus I detect some sounds I wasn’t hearing previously. Notably the roar of a Corvette exhaust while watching Wheeler Dealers.

Just wondering about anyone else’s experience. I am trying to maximize my Lumity 90s, I’ve been told by a top Chicago Hospital Otolaryngology dept that the next step is C.I. which I am opposed to having done.

I am also interested, as I have CI on the other side. I wonder which fitting formula would be more appropriate if the CI may give me a louder sound during the rehabilitation process.

Just reading the book about REM. If you don’t have dead regions at high frequencies, you can benefit from their greater gain in DSL 5.0. You can go even further by trying DSL 5.0 Pediatric.

The NAL-NL2 approach somewhat assumes that normalizing high-frequency loudness isn’t beneficial because of often dead regions (roughly speaking) that could lead to perceive a distortion or deterioration of speech understanding.
