@dollyh Hi Dolly. I heard back from the audiologist I know through the Facebook group on Oticon Opn hearing aids. Here is what she said:
LACE. By Neurotone
Listening and Communication Enhancement. You have to do all 16 sessions. Not just one here or there.
There is a charge for the sessions, it appears to be $79. I haven't signed up yet but think I will. I did sign up for email updates.

I also just purchased the book "Smart Hearing: Strategies, Skills, and Resources for Living Better with Hearing Loss" by Katherine Bouton. I haven't gotten far into it yet but if I find it valuable I will mention it on here.
