One Hearing Aid or Two?

If you have a loss in both ears, it is generally recommended to wear a hearing aid in both ears.  This will improve the quality of sound, particularly in social settings, allow you to localise sound better, and ensure you are consistently activating the pathways in your brain.

If you have a loss in one ear, you would typically use a hearing aid in the affected ear.

In cases where the other ear has no hearing, there is a hearing system called a Cros system that can help by sending signals to the dead ear and may allow some users to hear on both sides.
