Normal hearing individuals hear with both ears this is known as binaural hearing. It allows people to hear sounds accurately and more naturally. Two ears is much more helpful in noisy situations, it gives us a sense of balance and direction. When a person has a hearing loss usually it is symmetrical and there is a hearing loss in both ears. When a person has hearing loss in two ears and only wears a hearing aid in one ear it can make it more difficult to hear in noise, understand speech, and detect where sounds are coming from. It can result in straining to hear and cause fatigue.
