Types of Hearing Loss
Posted: 18/04/2023
In our last hearing blog we talked about the signs of hearing loss, this month we will explore the different varieties. Hearing loss can be caused by various factors, including genetics, exposure to loud noise, aging, infections, and certain medications. There are three main types of hearing loss: conductive, sensorineural, and mixed. If you are concerned that you may have hearing loss, you can do our online hearing test here or book an appointment.
Conductive Hearing Loss
Conductive hearing loss occurs when sound waves are not conducted efficiently through the outer and middle ear. It can be caused by blockages in the ear canal, such as earwax buildup or a foreign object, or by problems with the middle ear, such as fluid accumulation or damage to the eardrum or the tiny bones that conduct sound. Conductive hearing loss is usually temporary and can often be treated with medications or surgery.
Sensorineural Hearing Loss
Sensorineural hearing loss is the most common type of hearing loss and occurs when there is damage to the inner ear or the auditory nerve that transmits signals from the ear to the brain. It can be caused by aging, exposure to loud noise, genetics, infections, or certain medications. Sensorineural hearing loss is usually permanent and cannot be cured, but it can often be managed with hearing aids or cochlear implants.
Mixed Hearing Loss
Mixed hearing loss is a combination of conductive and sensorineural hearing loss. It occurs when there is damage to both the outer or middle ear and the inner ear or auditory nerve. Mixed hearing loss can be caused by a variety of factors, such as chronic ear infections or head trauma, and it may require a combination of treatments, such as medication, surgery, and hearing aids.
Other Types of Hearing Loss
There are also several other less common types of hearing loss, including:
Auditory Neuropathy Spectrum Disorder
Auditory neuropathy spectrum disorder (ANSD) is a type of hearing loss that occurs when the auditory nerve is damaged or malfunctioning, leading to distorted or inconsistent signals to the brain. ANSD can be caused by genetic mutations, infections, or head trauma, and it can often be managed with hearing aids or cochlear implants.
Sudden Sensorineural Hearing Loss
Sudden sensorineural hearing loss (SSHL) is a type of sensorineural hearing loss that occurs suddenly and without warning. It is usually caused by a viral infection or inflammation of the inner ear, and it can often be treated with steroids or other medications if caught early.
Tinnitus
Tinnitus is a condition where a person experiences a ringing, buzzing, or other sound in their ears that is not present in the environment. It can be caused by a variety of factors, including exposure to loud noise, aging, and certain medications, and it can often be managed with hearing aids or sound therapy.
In conclusion, hearing loss can have a significant impact on a person's quality of life, but with the proper diagnosis and treatment, many people can successfully manage their condition and continue to lead happy and fulfilling lives. It is important to seek attention if you are experiencing any symptoms of hearing loss, such as difficulty understanding speech or ringing in the ears, as early intervention can often improve outcomes.
