Some are small, some stick out farther than others and some are used as a handy way to keep the hair off our faces – but no matter how you view your ears, they’re one of the key organs we rely on to understand the world around us. When they don’t work correctly, it can be a frustrating, depressing and an even dangerous situation.
How Do We Hear? The Anatomy of the Ear and How We Hear, a new guide from Healthy Hearing, is a brief, descriptive overview of our ears and how sound travels through the ears to the brain. The guide is available as a free download from the Healthyhearing.com website.
In the guide, color graphics provide a cross-section illustration of the outer ear, middle ear and inner ear, with accompanying text which explains what function each part serves. Here, you’ll learn how the outer ear collects the sounds we hear and funnels them inside. A brief description of conductive hearing loss, which occurs in the outer and middle ear, is included.
Conductive hearing loss, which accounts for approximately 10 percent of hearing loss, is often medically treated with great success in restoring hearing. A link to more information on conductive hearing loss is also provided in this section.
Information on the inner ear includes an explanation of how the smallest bones in our body, located in the ear, pass sounds to sensory hair cells in the cochlea. The cochlea translates the vibrations it receives into a signal for the auditory nerve to deliver to the brain.
Sensorineural hearing loss also is defined in this section of the guide, along with a link to information hearing aids. Sensorineural hearing loss, often caused by damage to the inner ear hair cells, accounts for 90 percent of hearing loss and is most often treated with hearing aids or cochlear implants.
The guide ends with a warning on noise exposure and a good rule of thumb to follow in determining whether or not you’re living or working in an environment which may be detrimental to your ear health.
