Had an elderly man as a patient in a nursing home decades ago. Nice old guy, quiet, cooperative, with some slight confusion,and very hard of hearing. His wife would come and take him to church every Sunday, and bring him back in the evening. One time, she brought him back, and reported he had become unmanageable, very confused, belligerent, all of which was completely out of character for him. I was called to his room by an aide, and found him straddling his overbed table, (The table that you can place across the bed to eat, while in bed) whooping and acting like a mad man. While checking him over and getting him ready for bed, I removed his hearing aids, and they were turned up full blast, and ringing extremely loudly. Apparently, they had been ringing like that the entire day. He was never normal again. I am convinced that loud, constant ringing in his ears that day, pushed him over the edge.
I wonder if the volume change on his hearing aid was intentional. There are some strange people who work in nursing homes especially on the night shift.
We had a elderly lady at church that her hearing aids would squeal loudly, she was so deaf people had to tap her aids and do a high thumbs up until she understood they were squealing. She needed the newer ones, but no money for them. I have a Mid range pair, 1 up 1 down in volume. They need adjusted and new tips put on. The last ones got stuck in my ear canals. Kroger’s Little Clinic had to fish them out. LOL
