There are three main kinds of hearing loss: sensorineural (inner-ear or nerve damage, the most common type), conductive (a blockage or problem in the outer or middle ear), and mixed (a combination of both). The only way to know which one you have is a hearing test, which pinpoints the type, the degree, and the best treatment.
Hearing loss is a common issue. It can greatly affect how you live and interact with others. As audiologists, we aim to help you understand your hearing loss better. We also guide you on how to manage it effectively.
In this article, we will explore the different types of hearing loss. We will also explain how they are diagnosed. Knowing your condition is the first step to better hearing and overall well-being.
Types of Hearing Loss
There are three main types of hearing loss. These are conductive, sensorineural, and mixed. Each type has different causes, symptoms, and treatments.
Conductive Hearing Loss
Conductive hearing loss happens when sound cannot reach the inner ear. This may be due to blockages or other issues in the outer or middle ear. Common causes include earwax buildup, ear infections, or damage to the eardrum. Sometimes, the small bones in the middle ear can also be affected. With this type of hearing loss, sounds seem quieter than usual. You may also struggle to hear faint noises or whispers.
Diagnosis: An audiologist can diagnose this type of hearing loss. They will conduct a thorough check of your ears. This includes a physical examination, testing how your eardrum moves, and measuring your hearing levels with specialized equipment.
Treatment: The treatment depends on the cause of the blockage or damage. It might include ear wax removal, treating infections with antibiotics, or surgery to fix any damage in the ear. In some cases, hearing aids can also help improve hearing.
Sensorineural Hearing Loss
Sensorineural hearing loss is the most common type of hearing loss. It occurs when there is damage to the tiny hair cells in the inner ear. Problems with the auditory nerve can also lead to this type of hearing loss. This condition is often linked to aging, exposure to loud noises, or genetic factors.
Certain medical conditions, like diabetes or high blood pressure, can also contribute. It may be hard to understand speech, especially in noisy places. High-pitched sounds might also be difficult to hear clearly.
Diagnosis: An audiologist will conduct a detailed hearing test to diagnose sensorineural hearing loss. Speech audiometry is also used to assess how well you understand spoken words. In some cases, additional tests like otoacoustic emissions (OAEs) or auditory brainstem response (ABR) tests may be necessary.
Treatment: Sensorineural hearing loss is usually permanent and cannot be reversed. However, modern hearing aids or cochlear implants can greatly improve your ability to hear and communicate. These devices are designed to amplify sounds and make speech clearer.
Mixed Hearing Loss
Mixed hearing loss is a combination of conductive and sensorineural hearing loss. It often occurs when someone with sensorineural hearing loss also develops an issue in the outer or middle ear. The symptoms may include a mix of those seen in both types of hearing loss. For example, you might experience difficulty hearing both faint sounds and high-pitched noises.
Diagnosis: Diagnosing mixed hearing loss requires a comprehensive assessment. This might involve several tests, including pure-tone audiometry, speech audiometry, and imaging studies like CT scans or MRIs. These tests help the audiologist identify both the conductive and sensorineural components of your hearing loss.
Treatment: Treatment for mixed hearing loss depends on the specific causes. Medical treatment or surgery may be needed to address the conductive part of the hearing loss. Hearing aids or cochlear implants may be recommended to help with the sensorineural part.
Frequently Asked Questions
What is the most common type of hearing loss?
Sensorineural hearing loss is the most common type. It happens when the tiny hair cells in the inner ear or the auditory nerve are damaged, often due to aging, noise exposure, or genetic factors. Unlike conductive hearing loss, it is usually permanent, though hearing aids or cochlear implants can significantly improve hearing and speech clarity.
How does an audiologist diagnose the type of hearing loss I have?
An audiologist diagnoses hearing loss through a combination of tests, including pure-tone audiometry to measure hearing levels, speech audiometry to assess word understanding, and a physical exam of the ear and eardrum. For more complex cases, such as suspected mixed hearing loss, imaging tests like a CT scan or MRI may also be used to pinpoint both the conductive and sensorineural components.
Can conductive hearing loss be reversed, unlike sensorineural hearing loss?
Yes, conductive hearing loss is often treatable and can be reversible, since it stems from a physical blockage or damage in the outer or middle ear, such as earwax buildup, infection, or eardrum damage. Treatment may include ear wax removal, antibiotics, or surgery. Sensorineural hearing loss, by contrast, results from inner ear or nerve damage and is usually permanent, though hearing aids or cochlear implants can improve communication.
