If you can't switch them off then move to another room away from them. If there are a lot of people talking it may be better to move to a quieter room. In a noisy room avoid sitting in the corner where sound may be reflected from the walls. The kitchen is not usually a good place for conversation, as there are so many sounds to mask out speech-kettles, fridges, washers, pans, running water, cooking noises etc. If you live on a main road then try to hold conversations at the back of the house if possible, away from traffic noise.
Outdoor conversations can be difficult because of traffic noise.
Wind noise can affect your hearing aid. Try moving into a quiet spot away from the traffic, if you want to talk. In noisy places it can be helpful to adjust the volume of your hearing aid until the conversation is as clear as possible. If you switch your hearing aid off in a noisy place then take it out, or it will act as an earplug. Distance Try to sit or stand facing the speaker.
