Binaural hearing refers to the way in which our two ears work well together. This is important for localising sounds and for listening in background noise. Our brain is able to compare and contrast information received from each ear separately to determine what sounds are important to listen to, and what sounds can be ignored. When one or both ears are not working well, you may find it harder to hear speech clearly, particularly in background noise. This is why it is important to always manage hearing loss in both ears.
