Why You Need Two Ears

We’re often asked about why it’s important to wear two hearing aids.  The reasons listed below outline the advantages of binaural hearing (hearing with two ears). However a better way to think of this is that the human body doesn’t come with spare parts.  You need what you came with.  Having two of something does not make one an extra.  Try walking with one leg, or seeing with one eye.  Is it possible?  Of course it’s possible.  Is it easy?  No. Improved Understanding Binaural hearing helps you sort out and understand individual voices.  Our “built-in signal processor” blends signals from both ears into a single “picture”.  Without such equality, our brain can only present us with incomplete information. Less Stressful Listening Listening with only one ear is physically tiring and stressful.  The more realistic sound of stereo hearing lets you respond more confidently.  And you don’t need to worry about always turning your “good ear” toward sounds. Safety Our brain locates a sound source by measuring the tiny differences in duration and intensity between your ears and interpreted by your brain. This allows you to instantaneously recognize a sound’s exact location.  When a person hears with only one ear, the difficulty in locating sound can be dangerous, especially in traffic. Both Ears Stay Active When a hearing impaired person who has an equal hearing loss in each ear wears a hearing aid in only one ear, the unused ear tends to lose its ability to hear and to understand. Cushions Loud Sounds Binaural hearing generally requires less volume, giving a more natural sound to voices and music.  Sudden loud sounds lose much of their jarring effect when divided between two ears. Better Sound Identification Many noises, which sound almost exactly alike when heard with one ear can be identified more easily when heard with two ears. Hearing From Both Sides As nature intended, hearing with two ears allows you to enjoy more natural sound.  Hearing with one ear is like trying to see with one eye—it’s possible, but not very effective. Wider Hearing Range A voice barely heard at ten feet away with one ear can be heard up to 40 feet away with two ears.
