I DID tell them that right from the beginning! I know to do that from past experience.
I told the MD the same thing but they all seem to revert to their comfort zone in short order. This causes me to have another thought… if my employer is obligated to accommodate my disability, should they provide my HA’s?? 
I’m just blowing off steam, pay no attention! 
You hit right on about the comfort zone. Quite frankly people are uncomfortable around people they view as significantly different.
I had a detailed post that was removed that went into this comfort and requiring people with defects to modify themselves to be so called “NORMAL”
You more than meet them half way by having the aids in the first place. There was no excuse for the others to not come half way when your aids were down.
I been wearing aids for 30 years and I am not comfortable wearing them especially in new situations because the stupid stigma “DEAF AND DUMB” or your inferior.
first year I wore aids before starting school, had no issues at all, wearing them, that changed, when other people were introduced to the equation when school started and on.
I have the same issue you do and I am actually am wearing my aids on “max” volume. And No they do not needed to be adjusted up.
It especially becomes a problem in larger groups. People will not speak up when addressing a group. Even normal people can’t hear whats being said , how do they expect us to hear them then if normals can’t?
If we could all learn to be nicer to one another, then maybe, people would be willing to speak up without fear of belittling or other nasties? in general?.
