Mixed hearing loss is a type of hearing impairment that involves a combination of two different types of hearing loss: conductive and sensorineural. Conductive hearing loss occurs when sound waves are blocked from reaching the inner ear due to problems in the outer or middle ear. Sensorineural hearing loss, on the other hand, is caused by damage to the inner ear or the auditory nerve, which transmits sound signals to the brain.
When you have mixed hearing loss, it means you're experiencing both of these issues simultaneously. This can create a unique set of challenges when it comes to hearing and understanding sounds.
Causes of Mixed Hearing Loss
Genetic Factors
In some cases, mixed hearing loss can be caused by genetic factors. These factors may contribute to the development of both conductive and sensorineural hearing loss.
Ear Infections and Diseases
Ear infections, particularly chronic or recurrent ones, can lead to conductive hearing loss by causing fluid buildup or damage to the middle ear. Certain diseases, such as otosclerosis, can also affect the middle ear and contribute to mixed hearing loss.
Trauma and Injury
Head injuries or trauma to the ear can cause damage to the outer, middle, or inner ear, resulting in mixed hearing loss. Acoustic trauma, which is exposure to loud noises, can also contribute to sensorineural hearing loss.
Aging and Other Health Conditions
As we age, it's common to experience some degree of sensorineural hearing loss due to the natural deterioration of the inner ear. This, combined with age-related conditions that affect the outer or middle ear, can lead to mixed hearing loss. Certain health conditions, such as diabetes or autoimmune diseases, can also increase the risk of mixed hearing loss.
Symptoms of Mixed Hearing Loss
Difficulty Understanding Speech
One of the primary symptoms of mixed hearing loss is difficulty understanding speech, especially in noisy environments. This is because both conductive and sensorineural components contribute to the impairment.
Muffled or Distorted Hearing
Sounds may seem muffled or distorted, making it challenging to distinguish between different sounds or words. This can be particularly frustrating when trying to follow conversations or listen to music. You can find more information on common causes of muffled hearing on our blog.
Difficulty Hearing Soft Sounds
Soft sounds may be difficult or impossible to hear, which can impact your ability to hear whispers, quiet music, or sounds in the distance.
Tinnitus (Ringing in the Ears)
Tinnitus, a ringing, buzzing, or hissing sound in the ears, can be a symptom of mixed hearing loss, particularly when there is a sensorineural component involved.
Feeling of Fullness in the Ears
Some individuals with mixed hearing loss may experience a feeling of fullness or pressure in the ears, similar to the sensation you get when your ears need to pop.
How Symptoms May Differ from Pure Conductive or Sensorineural Loss
It's important to note that the symptoms of mixed hearing loss can vary depending on the severity of each component. In some cases, the conductive component may be more prominent, while in others, the sensorineural component may dominate. This can make it challenging to distinguish mixed hearing loss from pure conductive or sensorineural loss based on symptoms alone.
Diagnosis of Mixed Hearing Loss
Hearing Tests and Examinations
To diagnose mixed hearing loss, an audiologist will conduct a comprehensive hearing evaluation. This typically involves a variety of tests, including pure-tone audiometry, bone conduction testing, and speech audiometry. These tests help to determine the degree and type of hearing loss present.
Importance of Professional Evaluation
If you suspect you may have mixed hearing loss, it's crucial to seek a professional evaluation from an audiologist. They can accurately diagnose your condition and recommend appropriate treatment options based on your specific needs.
Managing Mixed Hearing Loss
Strategies for Everyday Living
There are several strategies you can implement to manage mixed hearing loss in your everyday life. These may include using assistive listening devices, such as hearing aids or cochlear implants, and using communication strategies, such as lip-reading or asking people to speak clearly.

Support and Resources
Connecting with others who have mixed hearing loss can provide valuable support and insights. Consider joining support groups or online communities to share experiences and learn about coping strategies.
Preventive Measures
While not all causes of mixed hearing loss are preventable, there are steps you can take to reduce your risk. These include protecting your ears from loud noises, managing underlying health conditions, and seeking prompt treatment for ear infections.
