What is Hearing Loss?

This type of hearing loss arises when sound waves encounter obstacles or hindrances as they attempt to traverse the outer or middle ear. Common culprits include earwax blockages, ear infections, or abnormalities in the ear's physical structure. Fortunately, many cases of conductive hearing loss are amenable to medical treatment or surgical intervention.

Sensorineural hearing loss stands as the most prevalent category and results from damage to the inner ear or the auditory nerve pathway that carries sound signals to the brain. It can develop due to a variety of factors, including aging (presbycusis), prolonged exposure to loud noises, genetics, certain medical conditions (such as diabetes or hypertension), and ototoxic medications. Sensorineural hearing loss is typically permanent and is commonly managed with hearing aids or cochlear implants.

This category combines elements of both conductive and sensorineural hearing loss. It often presents as a complex challenge, requiring a combination of medical interventions and the use of hearing aids or other assistive devices. Mixed hearing loss can result from conditions that affect both the outer/middle ear and the inner ear or auditory nerve.

In some cases, the issue isn't with the ears themselves but rather with the brain's ability to process sound. Central hearing loss occurs when there is damage or dysfunction in the central auditory processing centers of the brain. This can result from neurological conditions or brain injuries.
