What do I do if someone reported me to Adult Protective Services and the report is false

At first the investigator came out saying it was for ONE of my 5 residents. She just said it was about allegations of abuse. I took her to his room he of course confirmed he had not been abused nor threatened to be abused. She then came back the next day and said she had reports for all of my residents just didn't see them yet and that they were all being "threatened" with physical abuse, and yelled at. She then named me as the one they called about. I will admit I am loud. But I can't hear well they can't hear well and the pitch of my voice and it always sounds like a cold makes it hard for them to understand me. I have always been loud. 4 sets of tubes put in as a child and they all fell out the next day. I'm not yelling swear words and definitely not threats. Is it really abuse?
