It is best to start off in an environment where you can control the volume. Sit at home with the television on, or have a conversation across a table, with no other noise in the background. Modern hearing aids automatically select an optimal level, when they are switched on, and rarely need further adjustment. You may find that you need to turn the volume of the television down, or ask people not to shout as previously you required more volume to hear. If you have a volume control on your hearing aid, you may need to turn it down if you are finding voices are too loud or are sounding distorted.
