Sudden hearing loss can be alarming, especially when it happens unexpectedly in one ear. You may suddenly notice that sounds seem muffled, conversations are difficult to understand, or one ear feels blocked. Sometimes the cause is something simple, such as earwax buildup or fluid. In other cases, sudden hearing loss may be related to the inner ear and require prompt medical attention.
Understanding sudden hearing loss symptoms, causes, and treatment options can help you know when it is time to seek professional hearing care.
If you experience a sudden change in your hearing, scheduling a hearing evaluation as soon as possible is an important first step.
What Is Sudden Hearing Loss?
Sudden hearing loss is a rapid decrease in hearing that develops over a short period of time. It may affect one or both ears, although sudden hearing loss in one ear is common.
One important type is sudden sensorineural hearing loss (SSHL). This occurs when there is a problem involving the inner ear or the nerve pathways responsible for sending sound information to the brain.
Sudden hearing loss may be noticed when:
- You wake up and one ear sounds muffled.
- You suddenly have difficulty hearing on the telephone.
- One ear sounds significantly different from the other.
- Conversations suddenly become difficult to understand.
- You experience ringing or buzzing in your ear.
- Your ear feels full or blocked.
- You develop dizziness or balance problems.
Because sudden hearing changes can have different causes, it is important to have your hearing evaluated rather than assuming the problem is simply earwax or congestion.
Sudden Hearing Loss Symptoms
The symptoms of sudden hearing loss can vary depending on the underlying cause and severity.
Common sudden hearing loss symptoms include:
- Reduced hearing in one or both ears
- Muffled or distorted sounds
- Difficulty understanding speech
- A feeling of fullness or pressure in the ear
- Ringing or buzzing (tinnitus)
- Dizziness or balance difficulties
- Difficulty hearing on the telephone
- Increased difficulty following conversations in noisy environments
Some people experience sudden hearing loss and tinnitus at the same time. Others may notice dizziness or balance problems along with the change in hearing.
If these symptoms appear suddenly, don’t ignore them.
What Causes Sudden Hearing Loss?
There are many possible sudden hearing loss causes. In some cases, a specific cause can be identified, while in others, the exact cause remains unknown.
Possible causes include:
1. Earwax Buildup
A blockage caused by excessive earwax can temporarily reduce hearing and make your ear feel plugged or full.
However, it is important not to assume that sudden hearing loss is caused by earwax without having the ear examined.
2. Ear Infections or Fluid
An infection or fluid in the middle ear can interfere with the movement of sound and cause temporary hearing difficulties.
3. Viral or Other Infections
Certain infections may affect the structures involved in hearing and may contribute to sudden sensorineural hearing loss.
4. Head or Ear Injury
Trauma involving the head or ear can damage delicate structures responsible for hearing and may lead to sudden hearing changes.
5. Autoimmune Conditions
Certain autoimmune disorders can affect the inner ear and may contribute to rapidly changing or sudden hearing loss.
6. Blood Circulation Problems
The inner ear relies on a healthy blood supply. Problems affecting circulation may contribute to sudden sensorineural hearing loss.
7. Certain Medications
Some medications can damage the inner ear and affect hearing. These medications are sometimes called ototoxic medications.
8. Inner Ear Disorders
Conditions affecting the inner ear, including Ménière’s disease, can cause hearing changes along with tinnitus, ear fullness, and dizziness.
9. Unknown Causes
In many cases of sudden sensorineural hearing loss, doctors cannot identify one specific cause. This is sometimes referred to as idiopathic sudden sensorineural hearing loss.
A professional hearing evaluation can help determine what type of hearing loss you may be experiencing and whether further medical assessment is needed.
Sudden Hearing Loss in One Ear: Should You Be Concerned?
Yes. Sudden hearing loss in one ear should not be ignored.
You may initially think that one ear is blocked because of allergies, sinus congestion, or earwax. However, sudden hearing loss in one ear can sometimes be a sign of sudden sensorineural hearing loss.
If one ear suddenly sounds different from the other, seek professional evaluation promptly.
A hearing test can determine whether there is a measurable difference between your ears and help identify the type and degree of hearing loss.
Is Sudden Hearing Loss an Emergency?
Sudden sensorineural hearing loss can be a medical emergency.
If your hearing suddenly decreases, particularly in one ear, it is important to seek medical attention promptly rather than waiting several days to see whether your hearing returns.
Early evaluation is important because some cases of sudden sensorineural hearing loss may benefit from treatment when started promptly.
If you experience sudden hearing loss together with severe dizziness, neurological symptoms, or symptoms following a significant head injury, seek urgent medical attention.
When Should You See an Audiologist?
If you notice a sudden change in hearing, an audiologist can perform a comprehensive hearing evaluation to determine how well you are hearing and whether hearing loss is present.
You should consider scheduling a hearing evaluation if you experience:
- Sudden hearing loss in one ear
- New or worsening tinnitus
- Difficulty understanding speech
- A sudden feeling of ear fullness with reduced hearing
- Hearing loss accompanied by dizziness
- A noticeable difference between your ears
- Hearing changes after exposure to loud noise
Depending on the results of your hearing test, your audiologist may recommend further medical evaluation by an ENT specialist.
How Is Sudden Hearing Loss Diagnosed?
The first step in diagnosing sudden hearing loss is determining whether the hearing change is caused by a problem in the outer or middle ear or by a sensorineural problem involving the inner ear.
A hearing professional may perform several assessments.
Ear Examination
Your ears may be examined for:
- Earwax buildup
- Infection
- Fluid
- Eardrum abnormalities
- Other visible causes of hearing difficulty
Comprehensive Hearing Test
A hearing test measures your ability to hear different frequencies and volumes.
A hearing evaluation can help determine:
- Whether hearing loss is present
- Which ear is affected
- The severity of the hearing loss
- Whether the hearing loss is conductive or sensorineural
Additional Medical Testing
If sudden sensorineural hearing loss is suspected, an ENT specialist or other medical professional may recommend additional testing based on your symptoms and medical history.
Additional testing may include imaging, blood tests, or other evaluations when appropriate.
Sudden Hearing Loss Treatment
The appropriate sudden hearing loss treatment depends on the underlying cause and type of hearing loss.
If earwax, infection, or fluid is responsible, treatment may focus on resolving the underlying problem.
For sudden sensorineural hearing loss, medical treatment may include corticosteroids in appropriate patients. Treatment decisions should be made by a qualified medical professional based on your individual situation.
If hearing loss becomes permanent, hearing technology such as hearing aids may help improve access to speech and everyday sounds.
The sooner the cause of sudden hearing loss is evaluated, the sooner an appropriate treatment plan can be considered.
Can Sudden Hearing Loss Get Better on Its Own?
Sometimes hearing may partially or completely recover without treatment. However, you should not rely on spontaneous recovery.
If you experience sudden hearing loss, waiting to see whether it improves can delay diagnosis and potentially delay treatment when treatment is appropriate.
It is safer to have your hearing checked promptly.
Sudden Hearing Loss and Tinnitus
Sudden hearing loss and tinnitus can occur together.
Tinnitus is the perception of ringing, buzzing, humming, or other sounds without an external source. If you suddenly develop tinnitus along with reduced hearing, particularly in one ear, you should have your hearing evaluated.
A hearing test can help determine whether the tinnitus is associated with measurable hearing loss.
Sudden Hearing Loss and Dizziness
Some people experience sudden hearing loss and dizziness at the same time.
Dizziness or balance problems can sometimes indicate that the inner ear is involved. If you experience sudden hearing loss with significant dizziness, contact a healthcare professional promptly.
If dizziness is severe or occurs with other concerning neurological symptoms, seek urgent medical care.
How Can You Protect Your Hearing?
Not every form of hearing loss can be prevented, but protecting your ears from excessive noise can reduce your risk of noise-related hearing damage.
Helpful hearing protection habits include:
- Keep headphone and earbud volume at a reasonable level.
- Take breaks from prolonged headphone use.
- Wear hearing protection around loud machinery.
- Use appropriate ear protection at concerts and other loud events.
- Avoid standing close to very loud speakers.
- Give your ears recovery time after loud noise exposure.
- Schedule regular hearing evaluations if you have concerns about your hearing.
If you frequently work or spend time in noisy environments, ask an audiologist about appropriate hearing protection.
