Types of Hearing Loss
Different kinds of hearing loss require different treatments. it’s important to understand your hearing loss fully so you and your hearing health specialist can work out the best approach for your individual situation.
There are three primary types of hearing loss:
Conductive hearing loss is caused by a mechanical problem in the ear canal, eardrum or middle ear. With conductive hearing loss, the damage prevents sound from being carried properly to the inner ear.
Possible causes: infection, fluid, allergy, ear wax buildup, perforated eardrum, object in the ear, .tumor, misalignment of ossicles (the tiny bones in the middle ear), osteoarthritis, otosclerosis, trauma to the head,
Sensorineural hearing loss (SNHL) relates to problems of the inner ear and is usually the result of damage to the hair cells inside the inner ear. This type of hearing loss is also known as nerve-related hearing loss because it stems from changes to the nerves and sensory cells of the inner ear. Possible causes: aging, exposure to loud noise, head trauma, virus, disease, genetic hearing loss or tumor.
Mixed hearing loss is a combination of both conductive hearing loss and sensorineural hearing loss. This type of hearing loss indicates damage in both the outer or middle ear and the inner ear (cochlea) or auditory nerve. Possible causes: head injury, chronic infection or genetic disorder.
Hearing loss can affect one or both ears. It may occur suddenly or gradually worsen over time. As soon as you experience any signs of hearing loss, see a health care professional to get a diagnosis and the proper hearing loss information to address your individual condition.
