I have a similar audiogram with profound loss above 2 khz. I have avoided silicone molds, but use custom acrylic molds with a .8mm vent. I have had this loss for almost 40 years and have had various HA’s. Today I am using Phonak Naida P90 with 675 batteries. Sound recover works for me. Not perfect, but the birds are singing.
Make this at least one thing you try. Phonak bluetooth for my cell phone is excellent. You will never like noisy restaurants with any solution.
