Yes, by all means. CRANK IT UP TO 100% of your Rx/Prescription. Then leave it there unless it is uncomfortably loud for you.
A funny think happened to me. I developed a bad habit of not wearing my hearing aids first thing in the morning. Sometimes I waited to almost noon. So my brain trained itself to embrace the comfortable silence.
But that had an undesirable side effect. When I finally put my hearing aids on later in the day, some sounds were very loud and annoying. She doesn't like it if I accuse her of crunching on potato chips too loud! So now I put them on first thing in the morning and things are back to normal.
