Most experts agree that because gradual hearing loss typically occurs in both ears, it makes sense to fit both ears with hearing instruments. Think of it this way – to correct a vision problem in both eyes, would you wear eyeglasses with only one lens?
Advantages of wearing two hearing instruments include:
Localized sound – The ability to detect the direction and distance of sound can only be achieved with two ears.
Balanced hearing – Hearing with two ears will help you more accurately respond to sounds, like conversation on your left or right side.
Better speech comprehension – Balanced hearing with both ears may improve your ability to understand speech, both in background noise and in quiet situations.
