All five of our senses are amazing, and that includes hearing. Whether you are awake or asleep, your ears are always “on” when they are working properly. Understanding how hearing works can help you protect this amazing sense, as well as enable you to get help in the event that you struggle with hearing loss. To learn more about hearing, hearing loss, hearing aids, tinnitus (ear ringing) and more, talk with our audiology hearing specialists at Hearing Health Solutions today by calling 888-638-5095.
Sound Waves Enter the Ear
Sound waves constantly vibrate in the air all around us. Whether someone is speaking, playing the piano, ringing a bicycle bell, driving a truck, hammering a nail or tapping a pencil on the table, there are sound waves constantly flowing in all directions at once. And your ear picks them up all the time without any conscious effort from you.
Your outer ear (the visible parts on the sides of your head) funnels these sounds down through your auditory canal, which is the corridor leading down to your eardrum. The auditory canal is lined with glands that produce wax, as well as tiny hairs. Incidentally, that ear wax that we often find annoying is actually designed to clean, lubricate and protect your auditory canal from water, fungi, bacteria and insects!
Once the sound waves reach your ear drum, they cause it to tremble, which causes…
Middle Ear Vibrations
On the other side of your ear drum is the middle ear area. It is inhabited by three tiny, sensitive bones called “ossicles.” They are precisely arranged to respond to the vibrations caused by the sound waves bouncing on your ear drum. The first of these little bones is called the “hammer” (malleus). It taps on the next little bone called the “anvil” (incus), which then vibrates the third little bone called the “stirrup” (stapes). This middle ear chamber and the ossicles amplify the sound waves before sending them on to become…
Electrical Impulses in the Inner Ear
The inner ear is an amazing structure that houses the cochlea, which changes the mechanical vibrations of sound waves into electrical nerve impulses, and your vestibular system, which helps you stay balanced and orient your body as you move through space. (This is why damage in the inner ear often affects both hearing and balance.)
The cochlea is an amazing structure. It is filled with a special fluid and millions of tiny hair cells arranged throughout a corridor shaped somewhat like a snail shell. The opening of the snail shell has hair cells that detect lower sound frequencies or tones. As sounds travel through to the apex of the cochlea (or inner most reaches of the snail shell), the hair cells there progressively respond to higher frequencies. The hair cells then convert these frequencies into electrical impulses that are sent to the auditory nerve, which then sends all this…
Sound Information to be Interpreted by the Brain
Specifically, these impulses are sent to the brain’s central auditory cortex where all of the information gathered by your ears is processed so that you can tell whether you are hearing speech, the mechanical sounds of the construction equipment across the street, music playing on the radio, the toaster popping or your brakes grinding.
Hearing loss, auditory processing disorders and even balance disorders can occur whenever any part of this system, from the outer ear and the middle ear, to the inner ear and its hair cells and the central auditory cortex is damaged or dysfunctional.
If you are struggling with hearing loss or balance disorders, it is important to have hearing tests conducted by an experienced audiologist so that you can begin the right hearing health care regimen to alleviate the problem and improve your ability to hear, concentrate or balance.
There’s So Much More to Hearing
These are just the basics of how sounds in your environment are converted into to the electrical signals that your brain can then interpret and act upon. There is so much more to know and understand, particularly if any part of this amazing system fails to work as it should. Fortunately, modern technology has given us amazing resources to correct all kinds of hearing loss problems!
