This would be good for many noisy situations. Some hearing aids have more than one group of settings. A simple one-program hearing aid can be set for the listening situation that bothers you the most, or perhaps the one where you spend most of your time, such as near a noisy air conditioner in your office. Multiple-program hearing aids can be switched between programs whenever you like. For example, you might have one program for quiet conversation or music, and another for noisy situations where communication is difficult.
Some hearing aids have many different programs.
More programs are not necessarily better however, because switching between them and keeping track of which program you are using can be a bother. You switch between programs by pushing a button on the hearing aid or by using a remote control. Yes, even hearing aids can have remote controls, just like your television set. The remote controls typically are about the shape of a credit card and as thick as a pencil and operate by infrared light or radio signals. The radio control units can stay in your pocket or purse while you operate them.
