Binaural hearing: two ears hear better than one

Nature gave us two ears for a reason: Binaural Hearing, or hearing with both ears, helps us localise sounds no matter where they come from. It also allows us to precisely focus on what we want to hear by letting us perceive certain sounds like speech louder and clearer while ignoring others. A few of the most important binaural processes include binaural redundancy, binaural squelch, and binaural directed listening. 


Binaural redundancy


When we hear a sound in both ears, it’s like hearing the same sound twice. This helps our brain create a better perceptual image of the sound. With hearing loss, this effect is significantly reduced. Wearing two hearing instruments helps to bring back the benefit of binaural redundancy.


Binaural squelch


In situations where there is both noise and speech, hearing with both ears helps our brain to give speech sounds preference to noise. This makes speech seem louder than it really is. With hearing loss, this effect is significantly reduced. Wearing two hearing instruments helps to bring back the benefit of binaural squelch.


Binaural directed listening


In noisy situations with many different sounds coming from different places, hearing with both ears helps our brain pick out the one single sound source we’re interested in and focus on it. With hearing loss, this effect is significantly reduced. Wearing two hearing instruments helps to bring back the benefit of binaural directed listening.
