not a hearing aid wearer, but i do suffer from tinnitus, thus i cannot make out what someone is saying when there is loud background noise, I only realised that I rely on being able to see someones mouth when they are speaking with me as i can then tune in to what they are saying and hear them, mask wearing made my life more difficult as now anything said just gets added to background noise and i cant make out what someone is saying, that said if a noise does happen and its quiet in the background, I can hear a pin drop at three rooms away, I can also hear a conversation if I can see the persons mouth. so I guess I can lip read, but its more of a combination i use to sort out whats being addressed to me.
