Yes, for many people, the left and right ears handle sound a little differently. If you have hearing loss, one ear probably has more than the other-but even more than that, since birth, your ears have been partial to different sounds. (In other words, turn down the volume and use hearing protection if you have noisy hobbies, such as hunting or woodworking.) Do left and right ears handle sound differently? Hearing healthcare professionals agree: If you can limit your exposure to noise louder than 85 decibels, you can minimize the permanent damage to the hair cells of the inner ear.

According to the National Institute of Health, approximately 26 million Americans between the ages of 20 and 69 have hearing loss and as many as 16 percent of teens age 12 to 20 have reported hearing loss that may have been caused by NIHL.

Many things can damage these delicate hair cells, but noise-induced hearing loss (NIHL) is one of the most common-and preventable. Unlike the hair on your head, unfortunately, the hair cells in the inner ear do not grow back once they are damaged or die. When these hair cells die, you lose your ability to hear different sounds, depending on where the damaged stereocilia are located. The hair cells on one end of the carpet are responsible for translating vibrations for higher-pitched sounds and, much like a piano keyboard, those on the other end are responsible for sound vibrations in the lower register. These hair cells-approximately 16,000 of them-are rolled up like a carpet inside your cochlea. You cut and style the hair that grows on your head sometimes the hair on your arms and the back of your neck stands up on end when you’re feeling uneasy-but did you know you have a completely different set of sensory hair cells in your inner ear that are responsible for how you hear?Īlso known as stereocilia, the hair cells in the inner ear receive sound vibrations from the outer ear and change them into electrical impulses that they send to the brain along the auditory nerve. What are stereocilia and what do all those tiny hairs do?

Once the electrical impulses reach the brain, it interprets them into recognizable sound.

The inner ear translates the sound into electrical impulses and sends it along the auditory nerve.

Your outer ear (pinna) acts like a satellite dish to collect sound in our environment and funnel it to the inner ear.

Have you ever thought about what happens once sound enters your ears? Just as the brain interprets the images your eyes see, the brain is also responsible for interpreting the sound your ears collect. What happens when sounds enter your ears? Your brain interprets the sounds yourĮars collect. So, in honor of hearing enthusiasts everywhere, here are five things you may not know about how your hearing works. In fact, the way we hear is a fascinating and, sometimes mysterious, process. Our brain is processing the sounds our auditory system collects as automatically as we inhale and exhale. Truth be told, much of your hearing is on autopilot.

Beyond the likely suspects of people talking or the volume of the television, what’s going on in the background? Can you hear traffic? Is the neighbor’s dog barking? Are any of your appliances humming along? Stop for a moment and notice what you hear.
