Your brain needs to hear from both ears to be able to locate a sound. For example, if you hear with one ear, you will hear keys fall off the counter but not be able to tell exactly where they fell. When both ears hear equally, the brain can quickly locate the spot the keys fell. This is one reason why we typically recommend two hearing aids when you have hearing loss in both ears. Hearing aids work as a system. This way the brain receives more accurate information keeping you in touch with your surroundings.
The second benefit of wearing two hearing aids is better hearing in noisy places. With two hearing aids, the brain better separates words from background sounds. The more information the brain has the better you can focus on the conversation. This allows for easier communication even though there is background noise.
Today many hearing aids operate wirelessly. With wireless hearing aids, the aids communicate with each other maximizing hearing. This binaural processing coordinates sound giving the brain more accurate information. You have a better idea of things happening around you.
Research shows those who wear two hearing aids are more satisfied and those who wear one. Those who wear wireless hearing aids are the most satisfied.
