There are 3 type of hearing loss: Sensorineural, Conductive and Mixed.
The most common type of hearing loss is known as sensorineural. This type of hearing loss has several causes including heredity, noise exposure and most commonly aging. This type of hearing loss occurs in the inner ear and can involve the hearing nerve as well. Hearing aids are the most popular option for individuals with this type of hearing loss.
Conductive hearing loss involves an impediment to the conduction of sound waves to the inner ear. The presence of fluid and/or a mass located in the middle ear space can be responsible for blocking or impeding the transmission of sound to the inner ear. This type of loss is often medically treatable and is most commonly found in infants and children.
Lastly, mixed hearing loss is a combination of both conductive and sensorineural hearing loss.
