Short answer
If your hearing drops noticeably over hours or a few days, especially in one ear, seek medical assessment promptly.
The cause may be something relatively simple, such as earwax or a middle-ear problem. But you cannot reliably tell at home whether the change is coming from the ear canal, middle ear or inner ear.
That is why “I will wait a few days and see” is not a safe default for sudden unexplained hearing loss.
What counts as sudden?
People may notice it in different ways:
- waking up with one ear hearing worse;
- suddenly finding a phone much quieter on one side;
- a clear drop in hearing over a day or two;
- an ear feeling abruptly “blocked” or “switched off.”
Some people also notice tinnitus, a feeling of pressure or fullness, or dizziness.
Why you should not assume it is earwax
Earwax can reduce hearing, but a blocked-ear sensation can also occur with other conditions.
Until the ear is examined and hearing is tested, it may not be clear whether the problem is in:
- the ear canal;
- the middle ear;
- the inner ear;
- another part of the hearing pathway.
The safer approach is assessment rather than guessing.
What does the clinician usually check?
Ear examination
This can identify obvious problems such as wax, inflammation or changes in the eardrum.
Hearing test
Pure-tone audiometry compares the ears and shows how hearing thresholds differ across frequencies.
Additional testing when needed
Further tests are selected according to the findings and symptoms rather than automatically for everyone.
Why can this be urgent?
NIDCD treats sudden sensorineural hearing loss (Sudden sensorineural hearing loss is a rapid hearing change involving the inner ear or auditory pathway and requires medical assessment for diagnosis.) as a medical emergency. An online article cannot determine whether that is what an individual person has.
The patient-facing rule is simpler: if hearing suddenly and inexplicably drops, particularly in one ear, do not deliberately delay medical assessment.
What to do before medical assessment
The priority is not to guess the cause or use self-treatment as a substitute for an examination. When arranging care, say when the change began, which ear is affected and whether you also developed tinnitus, dizziness, pain, discharge or other new symptoms.
When are other symptoms an emergency?
If a sudden hearing change occurs together with new facial weakness, arm or leg weakness, speech difficulty, loss of consciousness, or a severe unusual headache, seek emergency medical care.
Those symptoms go beyond routine hearing assessment.
What if the hearing starts to come back?
If the drop was truly sudden and noticeable, it is still worth discussing with a clinician. Partial improvement does not by itself explain the cause.
Frequently asked questions
My ear suddenly feels blocked. Is that always hearing loss?
No. A blocked sensation has many possible causes. But if you are also clearly hearing less—especially in one ear—assessment is appropriate.
Can I wait until tomorrow?
With sudden unexplained hearing loss, intentional delay is not recommended. The appropriate urgency and next step can be determined after examination and hearing testing.
Could it be related to a cold?
Yes. Colds and middle-ear problems can affect hearing, but symptoms alone cannot reliably distinguish them from other causes.
There is no pain. Is that reassuring?
Not enough. Significant hearing loss can occur without ear pain.
Can I try treating it myself first?
Self-treatment cannot reliably identify where the hearing change is coming from and may delay appropriate assessment. With a sudden unexplained change, examination and hearing testing come first.

If hearing changes suddenly
The priority is not to guess the cause at home, but to obtain medical assessment promptly.
1. Note what changed
When the change started, which ear is worse, and whether new tinnitus, fullness or dizziness appeared.
2. Do not delay medical assessment
A sudden unexplained drop in hearing, especially in one ear, warrants prompt professional assessment.
3. Do not substitute self-treatment for examination
Symptoms alone cannot reliably distinguish an ear-canal or middle-ear problem from an inner-ear change.
Goal
Work out where the hearing change is coming from and what the appropriate next medical step is.
