How We Hear
- Outer Ear
- Middle Ear
- Inner Ear
The pinna collects sound waves as they move through the air and directs them into the external ear canal where they are carried directly to the tympanic membrane (eardrum).
The tympanic membrane vibrates in response to sound waves. Sound vibrations move from the tympanic membrane through the ossicles (middle ear bones) to the cochlea.
Sound vibrations cause the fluid and tiny hair cells inside the cochlea to move. Neural signals are created by movement of the hair cells and those signals activate the auditory nerve. The auditory nerve signals the auditory cortex of the brain and those signals are interpreted as sounds and speech.

Our Hearing and Hearing Loss Department
Hearing loss occurs when sound is blocked from getting to the brain. A number of problems can prevent sound from being properly transmitted at any point along the normal route described above. The most common cause of hearing loss (and most preventable) is exposure to loud noise. Infections, both of the ear or elsewhere in the body, are also a major contributor to hearing loss. Most causes of outer ear hearing loss can be remedied, but problems of the middle and inner ear can lead to permanent hearing loss. It is important to seek medical attention quickly if you are experiencing a problem hearing, especially if hearing loss is a sudden change. Here are some common causes of hearing loss depending on the location of the problem:
- In the Outer Ear: Ear wax build-up, infections that cause swelling, a growth in the ear canal, injury, or birth defects can restrict hearing in the outer ear.
- In the Middle Ear: Fluid build-up is responsible for the most common infections in the middle ear. Fluid in the middle ear prevents the bones from processing sounds properly. Tumors, both benign and malignant, can also result in hearing loss in the middle ear.
- In the Inner Ear: Aging effects and long-term noise exposure cause damage to the cochlea (hearing organ), vestibular labyrinth (which regulates balance), or the auditory nerve (nerve that sends sound signals to the brain).
Other causes of hearing loss include:
- Presbycusis: Age-related hearing loss, such as having difficulty hearing in noisy places, having trouble understanding what people are saying, or not registering softer sounds.
- Meniere’s Disease: An inner ear disorder that causes hearing loss, vertigo/dizziness and sometimes ringing.
- Heredity and Genetic Causes: Many diseases and syndromes that are either genetic or hereditary can cause hearing loss. Some, like rubella (German measles) occur when a pregnant mother has the disease, which causes hearing loss in the baby. Other, rarer types of hereditary and genetic causes include CHARGE Syndrome, Connexin 26 disorder, Goldenhar Syndrome,Treacher Collins Syndrome, Usher Syndrome and Waardenburg Syndrome.
- Otosclerosis: A hereditary disorder caused by growth of spongy bone tissue in the middle ear. This results in abnormal sound transmission through the middle ear bones causing muffled hearing.
- Cholesteatoma: A benign growth starting in the middle ear that erodes bone and the eardrum.
