May 31: Save Your Hearing Day
Hearing loss is the result of noise, aging, disease, and heredity. There are two types of hearing loss, conductive and sensorineural.
Conductive hearing loss is interference of sound waves traveling from the outer ear to the inner ear. This is causes by inner ear infections, fluid in the middle ear, excessive wax, damage to the eardrum, or a bone growing in such a way that it blocks the sound waves from traveling from the middle ear to the inner ear.
Sensorineural hearing loss is when hair cells in the inner ear are damaged. This is due to age, injury from a trauma or noise, pressure in the inner ear, stroke, benign lesions, and brain tumors.
Hearing loss is also one of the most preventable diseases. Even though loud noises may be all around us, wearing earplugs can help reduce noise level.
