Hearing loss in one ear for a few seconds (Sudden Brief Unilateral Tapering Tinnitus, or SBUTT) is often due to temporary inner ear changes, Eustachian tube issues from colds/allergies, or pressure shifts, but can sometimes signal more serious problems like viral infections, circulation issues, or rare tumors (acoustic neuroma), so seeing a doctor is important to rule out severe causes, especially if it happens often.
In some cases, sudden hearing loss may be caused by a temporary blockage, such as accumulated earwax or congestion from allergies, a sinus infection or the common cold.
Here are some of the most frequent causes: Earwax blockage: When earwax builds up excessively, it can prevent sound from reaching the eardrum. Fluid accumulation: Often linked to sinus infections, allergies or colds, fluid in the middle ear can create a plugged or muffled sensation.
Causes may include head injuries, infections, ear blockages, tumours, or genetic conditions. Whether the hearing loss is permanent depends on the underlying cause — for example, wax or fluid buildup may be treatable, while damage from a tumour may be irreversible.
The primary indicator of an ear stroke is a rapid loss of hearing in one ear, but other symptoms often accompany it. These may include a feeling of fullness in the ear, dizziness, vertigo and tinnitus, which is a ringing or buzzing sound. Some people might also feel off-balance or experience nausea.
Other signs and symptoms may include:
Muffled Hearing: Dehydration affects the cochlea, a fluid-filled chamber in the inner ear that transmits sound vibrations to tiny hair cells. These hair cells convert the vibrations into electrical signals for the brain. Reduced fluid levels impair this process, potentially causing muffled hearing.
Depending on the sound decibel, a temporary threshold shift can occur in the ear canal after one incident or repeated exposure. The human ear typically recovers from noise exposure on its own and normal hearing gradually returns. Something else could be impacting the ears if full hearing doesn't return as expected.
Stroke can also result in sudden hearing loss. Usually this loss comes with vertigo, a sensation of movement or spinning. It can also cause difficulty with balance, nausea and vomiting. Most patients show partial or complete recovery of hearing loss by 1 year after stroke.
As the tumor grows, symptoms may become more noticeable or may worsen. Common signs and symptoms of an acoustic neuroma include: Hearing loss, usually gradually over months to years. In rare cases, hearing loss can be sudden.
Symptoms include:
While some causes of muffled hearing are minor and go away on their own, others need prompt attention. Seek medical care if you experience: Sudden hearing loss in one ear. Hearing that doesn't return to normal within a few days.
Meniere's disease
It causes hearing loss that comes and goes, ringing in the ears, and dizziness. Treatment for Meniere's requires the help of an ENT physician as well as a hearing specialist. A related condition, known as endolymphatic hydrops, can also cause intermittent hearing loss.
Stress disrupts the body's ability to return to a calm state, potentially leading to heart-related diseases, hypertension or other health issues that compromise blood circulation. This, in turn, can damage the inner ear's hair cells, leading to sensorineural hearing loss.
The difference between hearing loss and clogged ears often lies in the symptoms. Clogged ears usually cause a sensation of fullness and can be resolved by clearing an earwax blockage. Hearing loss, however, is more persistent, affects both ears more often, and tends to gradually worsen over time.
Symptoms
Remember the “4 P's” of Hearing Loss: it is Painless, Progressive, Permanent—but most importantly, Preventable.
The eight red flags are:
Pain or discomfort in the ear; Acute or chronic dizziness; Audiometric air-bone gap equal to or greater than 15 dB at 500, 1000, and 2000 Hz (ie, a hearing care professional would have to discover this); History of sudden or rapidly progressive hearing loss within the previous 90 days, and.
If left untreated, excessive earwax may cause earwax impaction symptoms to worsen. These symptoms might include hearing loss, ear irritation, tinnitus and other issues. A buildup of earwax might also make it difficult to see into your ear, which may result in potential issues going undiagnosed.
Fluctuating hearing loss has several causes, including ear infections, continued exposure to loud noises, ear wax buildup, autoimmune inner ear disease (AIED) and Ménière's disease.
Given the benefits of being able to socialize better with the people around you and the potential risks of untreated hearing loss, anyone with even mild hearing loss should consider getting a hearing aid. If you notice any symptoms of hearing loss, you should see an audiologist who can test your hearing.
