I know it. However the graphs gives us conclusion - the more occluded fittings → improved feedback resistance → HA can achieve gain closer desired levels (lighter curves) → better performance in hearing (in reality in my case it is poorer in gym
/restaurant compared to my old Bolero V70, sounds are muffled and dull and I feel isolated from talkers speech).
Maybe it isn’t the problem from desired gain, maybe more with the automatics. Now I try AutoSenseOS with turned off Speech in loud noise (unfortunately I can’t set higher treshold to turn on it) - I will see the results.
