Conductive vs Sensorineural Hearing Loss

  • Jul 16, 2023

Did you know that hearing loss isn’t as black and white as you might think? That there are different types of hearing loss, each with unique causes, symptoms, and treatments? If you’re interested in understanding more about hearing loss, its variations such as conductive vs sensorineural hearing loss, and how it can be prevented, you’re in the right place.


Short Summary

  • Conductive hearing loss is caused by obstructions in the outer or middle ear, while sensorineural hearing loss originates from an issue between the ear and nervous system.
  • Mixed Hearing Loss is a combination of both types, with causes ranging from illnesses to genetic factors. Diagnosis involves audiometry and tympanometry tests.
  • Preventing hearing loss requires reducing exposure to loud noises, managing blood pressure & cardiac health, quitting smoking and regular checkups using audiometric testing.


Understanding Conductive Hearing Loss

deafness, deaf, lack of hearing


Ever wondered why sometimes you can’t hear well even if there’s no loud noise around? This could be due to conductive hearing loss. This type of hearing loss occurs when there’s a problem conducting sound waves anywhere along the route through the outer ear, eardrum, or middle ear. It’s like trying to hear a conversation in a noisy room - the sound is there, but it’s just not reaching you properly.



Interestingly, conductive hearing loss is different from its counterpart, sensorineural hearing loss. Conductive hearing loss occurs due to issues in the external or middle ear space. Sensorineural hearing loss, on the other hand, arises from a problem in the connection between the ear and the nervous system. It’s like comparing a blocked pipe to a faulty tap - both can disrupt the flow of water, but the problem lies in different areas.


Causes of Conductive Hearing Loss

Now, you might be wondering, what causes conductive hearing loss? It’s often due to obstructions in the outer or middle ear. Imagine your ear as a busy highway. Now, what happens if there’s an accident on the road? Traffic slows down, right? Similarly, things like:


  • Earwax impaction
  • Infections
  • Foreign objects
  • Abnormal growths


In the affected ear, issues in the outer or middle ear can obstruct the “traffic” of sound waves, causing conductive hearing loss.


And just like how an accident can be caused by different factors, so too can conductive hearing loss. Earwax impaction, akin to a traffic jam, occurs when there is an accumulation of earwax in the ear canal, thus preventing sound from reaching the eardrum. Infections such as otitis media and otitis externa are like road construction, further blocking the path of sound. All these causes are like different accidents disrupting the smooth flow of traffic - or in this case, sound.


Symptoms and Detection

Have you noticed any difficulty in hearing conversations or sounds when background noise is present? If so, it might be an indication of conductive hearing loss. It’s best to consult a doctor for a thorough checkup. It’s more than just not being able to hear well. Symptoms include difficulty perceiving soft sounds, muffled perception of louder sounds, and a sensation of fullness in the ear. It’s like trying to listen to a radio station that’s out of range - the signals are there, but they’re just not coming through clearly.


To confirm if you have conductive hearing loss, doctors can perform various tests. Imagine a mechanic trying to figure out what’s wrong with a car. They would run diagnostics, right? Similarly, doctors use tests to determine if the problem lies in the outer or middle ear, such as:


  • A buildup of earwax
  • Fluid in the middle ear
  • A punctured eardrum
  • A problem with the little bones in your ear known as ossicles.


Treatment Options for Conductive Hearing Loss

Once diagnosed, how is conductive hearing loss treated? Treatment options are as varied as the causes themselves. These may include medication, surgical intervention, or the use of hearing aids, depending on the cause and severity of the condition. It’s like fixing a broken car - the solution depends on what’s broken.


For instance, if the cause is an infection, antibiotics or anti-fungal medications may be used. If the eardrum is damaged or there’s a foreign object in the ear canal, a surgical intervention may be required. In some cases, hearing aids may be used to amplify sound and enhance hearing. It’s all about finding the right tool for the job to get your “car” back on the road.


Understanding Sensorineural Hearing Loss

Now, let’s shift gears and talk about sensorineural hearing loss. This type of hearing loss happens when there’s damage to the inner ear or auditory nerve. Think of it as a problem with the car’s engine or transmission - it’s not about the path the sound takes, but rather the parts that process the sound.


One common cause of sensorineural hearing loss is prolonged exposure to loud noises, which can cause permanent hearing loss due to damage to the hair cells in the inner ear. However, sudden sensorineural hearing loss can also occur, and it’s like revving your car’s engine for too long - eventually, it’s going to cause some damage.


Causes of Sensorineural Hearing Loss

Just like conductive hearing loss, sensorineural hearing loss can also have various causes. Some potential causes include:


  • Noise exposure
  • Aging
  • Head injuries
  • Infections
  • Genetic factors


It’s like how a car can break down due to multiple reasons - old age, accidents, manufacturing defects, and so on.


For example, the biological aging process is the primary source of age related hearing loss, which is a type of sensorineural hearing loss, similar to how an old car tends to break down more often. Genetic factors, like Pendred syndrome and Usher syndrome, can also lead to sensorineural hearing loss. It’s a complex issue with many potential causes, just like diagnosing a car problem.


Symptoms and Detection

How can you tell if you have sensorineural hearing loss? Symptoms include difficulty comprehending speech, particularly in noisy environments, and a decrease in sound clarity. It’s like trying to listen to a radio station with a lot of static - you can hear the sound, but it’s not clear.


To diagnose sensorineural hearing loss, doctors can perform a comprehensive audiometric evaluation, which is like a mechanic running a thorough diagnostic test on a car. Early detection and immediate intervention are crucial to prevent further hearing loss and ensure that any hearing loss is addressed promptly.


Treatment Options for Sensorineural Hearing Loss

Once diagnosed with sensorineural hearing loss, what are the treatment options? Again, it depends on the severity of the condition. Treatment options may include hearing aids, cochlear implants, and assistive listening devices. It’s like fixing a car - the solution depends on the severity of the problem.


Hearing aids, which are the most common form of treatment, are like a mechanic tuning up a car to improve its performance. A hearing aid, in this analogy, represents the fine-tuning process. Cochlear implants, on the other hand, are like replacing a faulty part of the car.


While assistive listening devices, such as alerting devices, vibrating alarm clocks, and captioned phones, can provide a comprehensive hearing solution, like installing a GPS or hands-free device in a car to improve the driving experience.


Mixed Hearing Loss: A Combination of Both Types

Just like a car can have multiple problems, you can also have a combination of both conductive and sensorineural hearing loss, known as mixed hearing loss. It’s like having both a blocked road and a broken car - sounds find it difficult to pass through, and the sounds that do pass through aren’t processed correctly.


Treatment for mixed hearing loss can be more challenging. This is because the inner ear and air-bone gap both need to be diagnosed and addressed simultaneously. It’s like trying to fix both the car and the road at the same time - a complex process that requires a comprehensive approach.


Causes of Mixed Hearing Loss


  1. What are the factors behind mixed hearing loss?
  2. How is mixed hearing loss caused? Just like how a car and a road can both have multiple problems, mixed hearing loss is caused by a combination of conductive and sensorineural hearing loss. Potential causes include illness, drugs, genetic factors, head trauma, malformation of the inner ear, earwax, fluids in the middle ear, ear infections, perforated eardrums, and malformation of the outer or middle ear.


These causes can affect both the outer/middle ear and the inner ear or auditory nerve, leading to mixed hearing loss. It’s like a car with both engine problems and flat tires - multiple issues compound to create a bigger problem.


Unmissable Signs That Tinnitus is Going Away

Tinnitus, characterized by ringing, buzzing, or other sounds in the ears, can greatly affect one’s quality of life. With a wide range of potential causes and varying levels of severity, it’s important to understand the signs of improvement and how to effectively manage and prevent tinnitus.


This blog post will guide you through recognizing the signs that tinnitus is going away, differentiating temporary and permanent tinnitus, exploring treatment options and preventative measures, and knowing when to seek professional help.


Symptoms and Detection

Do you think you have mixed hearing loss? If so, consult your doctor to get a hearing test done and confirm. Symptoms include:


  • Difficulty in perceiving faint sounds
  • Difficulty in comprehending speech, particularly in boisterous surroundings
  • A blend of indications from conductive and sensorineural hearing loss


It’s like trying to drive a car with a faulty engine on a bumpy road - both the car and the road conditions contribute to the rough ride.


To confirm a diagnosis, doctors use a range of assessments, including audiometry and tympanometry, to determine the type and degree of hearing loss. It’s like taking a car to a mechanic - they’ll run a series of tests to figure out what’s wrong.


Treatment Options for Mixed Hearing Loss

Once diagnosed, how is mixed hearing loss treated? As you might guess, treatment options for mixed hearing loss are a mix of those for conductive and sensorineural hearing loss. This can include a combination of medical or surgical intervention, and sound amplification devices such as hearing aids, depending on the severity of the condition.


Specific treatment options can depend on the underlying causes and may include a combination of medications, surgery, and hearing aids or cochlear implants. It’s like fixing a car - sometimes you need to fix the engine, sometimes you need to replace the tires, and sometimes you need to do both.


Preventing Hearing Loss: Tips and Strategies

So, how can you prevent hearing loss? It’s like maintaining a car - you need to take steps to keep it running smoothly. This can involve avoiding loud noises, wearing ear protection in noisy environments, and getting regular hearing checks.


Managing blood pressure and cardiac health can also help, as well as quitting smoking and reducing exposure to loud sounds. It’s like keeping your car’s oil changed, tires rotated, and engine checked regularly - taking these steps can keep your car, or in this case your hearing, running smoothly for a long time.


Noise-Induced Hearing Loss Prevention

One of the most common causes of hearing loss is noise exposure, so it’s important to protect your ears from loud noises. This can involve using earplugs or noise-cancelling headphones, and taking breaks from noisy environments. It’s like putting a protective cover on your car to protect it from the elements.


You can also reduce your exposure to loud noises by turning down the volume, avoiding loud activities and places, and using noise-cancelling headphones or earplugs. It’s like driving a car - you need to follow the rules of the road to stay safe.


Regular Hearing Checkups

Just like regular car maintenance can prevent major problems, regular hearing checkups can help detect hearing loss early and monitor any changes in hearing over time. This allows for prompt intervention if needed.


Getting regular hearing checks can also:


  • Improve communication
  • Promote social engagement
  • Prevent distress, frustration, and embarrassment
  • Allow providers to prescribe treatment


It’s like getting a regular oil change for your car - it keeps things running smoothly and can prevent bigger problems down the road.


Hearing Tests and Diagnosis

To detect hearing loss, doctors use a variety of tests. This is like a mechanic running diagnostics on a car to figure out what’s wrong. The two most common tests are audiometry and tympanometry.


These tests are like a mechanic checking the engine and tires - they look at different aspects of hearing to get a complete picture of what’s going on.



Audiometry is a test that measures a person’s ability to hear different sounds, pitches, and volumes. It’s like a mechanic checking the car’s engine performance under different conditions.


With audiometry, doctors can assess a person’s hearing ability and determine the type and degree of hearing loss. It’s a vital tool for diagnosing hearing loss and monitoring its progression over time.



Another important test is tympanometry, which assesses the movement of the ear drum in response to changes in air pressure. It’s like checking the car’s suspension - it can reveal problems that affect how smoothly the car runs.


Tympanometry can help identify issues with the middle ear that may contribute to hearing loss, such as fluid or a perforated eardrum. It’s a crucial part of the diagnostic process for hearing loss, just like a suspension check is a crucial part of diagnosing car problems.



In conclusion, hearing loss is a complex issue with many causes, symptoms, and treatment options. Whether it’s conductive, sensorineural, or mixed, understanding the type of hearing loss can help identify the best treatment options. Just like maintaining a car, preventing hearing loss involves taking steps to protect your hearing and getting regular checkups. By understanding more about hearing loss, you can take steps to protect your hearing and improve your quality of life.
