The Ear and Hearing Loss
Learning about ear or hearing problems is helped with an understanding of the parts of the ear and how they function together. These articles describe what is needed for hearing, and how they are tested to identify the cause of hearing loss.
What Is Needed to Hear?
The necessary tools for good hearing include an open ear canal and a functional middle and inner ear, as well as a functioning auditory system within the brain.
How Do We Hear?
Sound is derived by the vibration of air. The mechanism of hearing begins with the vibration of air which is collected by the outer ear and directed through the ear canal towards the ear drum.
What Comprises Hearing Loss?
When testing for hearing loss, the entire hearing apparatus from the outer ear to the inner ear is tested as well as the inner ear itself, as well as a speech test. This helps us to localize the site where hearing may be impaired.
