Mixed hearing loss refers to a condition that includes both sensorineural and conductive hearing loss. In other words, sound is having difficulty traveling through the outer or middle ear (conductive component) and there is also damage to the inner ear or auditory nerve (sensorineural component).
This type of hearing loss can range in severity and often varies significantly from one person to the next. It can develop gradually over time or result from a sudden injury or illness. Understanding what mixed hearing loss means, how it affects you, and what treatments are available can help you take the next step toward clearer, more comfortable hearing.
What Causes Mixed Hearing Loss?
Mixed hearing loss is not the result of a single problem. It typically develops from two different issues affecting different parts of the auditory system. One form of hearing loss may already exist when the other develops, or they may emerge around the same time due to illness, injury, or age.
The most common causes include:
-
Aging (presbycusis): As people age, the delicate hair cells in the inner ear begin to deteriorate. At the same time, older adults may also experience wax buildup or stiffness in the middle ear bones, leading to a combined hearing loss.
-
Chronic ear infections: Longstanding infections can damage the eardrum or middle ear bones, while also increasing the risk of inner ear complications.
-
Head trauma or skull injuries: An accident or serious injury can affect both the middle ear structures and the cochlea or auditory nerve.
-
Prolonged noise exposure: Repeated exposure to loud environments, such as industrial workplaces or concerts, may damage the inner ear while also leading to complications like fluid buildup or ruptured eardrums.
-
Genetic factors or medical conditions: Some individuals are born with abnormalities affecting both the conductive and sensorineural pathways. Others may develop mixed hearing loss due to autoimmune conditions, tumors, or otosclerosis.
In short, mixed hearing loss is often the result of a complex interaction between internal and external factors, and the underlying causes must be evaluated thoroughly before starting treatment.
Common Symptoms of Mixed Hearing Loss
Recognizing mixed hearing loss can be tricky because it presents symptoms from both types of hearing damage. You may notice that sounds seem quieter than they used to, but also less clear or distorted. Some people describe it as hearing others “mumble,” even when they speak loudly.
You might experience:
-
Muffled or distorted hearing
-
Difficulty understanding conversations, especially in noisy environments
-
Frequently asking people to repeat themselves
-
Turning the TV or phone volume up higher than usual
-
Buzzing or ringing in the ears (tinnitus)
-
Fatigue after trying to follow conversations
-
Avoidance of social gatherings due to frustration or embarrassment
The key difference with mixed hearing loss is that you are likely dealing with both volume and clarity issues. That makes everyday listening more exhausting, especially in group settings or when background noise is present.
How Is Mixed Hearing Loss Diagnosed?
Diagnosing mixed hearing loss requires a full hearing evaluation. A trained audiologist will perform a series of tests that measure how sound travels through each part of your ear and how well your inner ear and auditory nerve process it.
Two essential tests are:
-
Air conduction testing: This evaluates your ability to hear sounds as they travel through the outer ear, middle ear, and into the inner ear. Headphones or ear inserts are used to deliver sounds at different pitches and volumes.
-
Bone conduction testing: A small device is placed behind your ear to send vibrations through the bones of your skull. This test bypasses the outer and middle ear, going straight to the cochlea to test inner ear function.
If your bone conduction test shows hearing loss and your air conduction test shows an even greater hearing loss, this usually points to a mixed hearing loss. In some cases, additional tests like tympanometry or speech recognition assessments may be used to confirm the diagnosis.
Proper diagnosis is critical because treatment for mixed hearing loss often requires addressing two different types of hearing problems. Only a thorough evaluation can reveal the best next steps.
Treatment Options for Mixed Hearing Loss
Because mixed hearing loss affects multiple areas of the auditory system, treatment must be tailored to the individual. Often, this means combining medical treatments for the conductive portion with hearing technology for the sensorineural component.
Medical and surgical treatment options may include:
-
Removal of earwax or foreign objects in the ear canal
-
Treatment of infections with antibiotics or corticosteroids
-
Surgery to repair the eardrum or middle ear bones
-
Pressure equalization (PE) tubes to relieve fluid buildup in the middle ear
Once the conductive issues have been addressed, or if they are permanent, your provider may recommend hearing aids or implants to improve your ability to hear and understand speech.
Hearing technology options may include:
-
Digital hearing aids that are programmed to compensate for both clarity and loudness
-
Bone-anchored hearing systems for patients with significant middle ear damage
-
Cochlear implants if hearing loss is severe and traditional aids are not effective
It’s important to work with an audiologist or ENT specialist who can develop a comprehensive treatment plan. Some individuals may benefit from a combination of solutions, such as surgery to correct conductive damage followed by hearing aids to address sensorineural loss.
Living with Mixed Hearing Loss
Living with mixed hearing loss can impact your communication, relationships, and overall well-being. However, the good news is that treatment options are available and often quite effective, especially when started early.
Here are a few strategies that can make everyday life more manageable:
-
Schedule regular hearing checkups. Hearing loss can change over time, and your treatment may need adjustments.
-
Use visual cues. Face the person speaking and pay attention to lip movements and facial expressions.
-
Choose quieter settings. Reducing background noise can help you focus on conversations more easily.
-
Practice clear communication. Let others know how they can support you, whether it’s by speaking slowly or rephrasing rather than repeating.
-
Explore assistive devices. Options like captioned phones or TV amplifiers can make a big difference in everyday comfort.
Support groups and hearing health communities can also offer emotional support and practical advice for navigating mixed hearing loss over time.
Key Takeaways
-
Mixed hearing loss involves damage in both the outer/middle ear and the inner ear or auditory nerve.
-
Common causes include aging, chronic infections, injury, and noise exposure.
-
Treatment often includes both medical intervention and hearing aids or other technology.
Frequently Asked Questions
Can mixed hearing loss be reversed?
Some causes of mixed hearing loss, particularly the conductive portion, may be reversible with medication or surgery. However, the sensorineural component is typically permanent and managed with hearing devices.
What are the signs of mixed hearing loss?
You may notice muffled hearing, difficulty understanding speech, or feeling like people are talking clearly but you can’t quite make out the words. You might also turn up the volume often or avoid social situations.
How is mixed hearing loss diagnosed?
An audiologist will use both air and bone conduction hearing tests to identify where the hearing loss is occurring. A greater loss in air conduction than bone conduction typically signals a mixed hearing loss.
Are hearing aids enough to treat mixed hearing loss?
In many cases, yes—especially if the conductive issue is mild or already treated. However, more severe conductive problems may require surgery or medical treatment before hearing aids can work effectively.
Is mixed hearing loss more serious than other types?
Not necessarily, but it can be more complex to manage because it involves multiple areas of the ear. A personalized treatment plan is key to getting the best outcome.
