hearing on one side

Overview

Hearing loss in one ear, also called unilateral hearing loss, means it is harder to hear sounds in that ear while the other ear works normally. It can be mild, moderate, or severe, and it may appear suddenly or develop gradually over time.

Hearing loss in one ear is not as common as hearing loss in both ears, but many people do experience it at some point in their lives.

It can affect anyone, but it is more common in adults, particularly those with certain health conditions or a history of repeated loud noise exposure.

Symptoms

Common symptoms

• Muffled hearing in one ear
• Trouble following conversations when there is background noise
• A feeling that one ear is blocked or full
• Ringing, buzzing, or hissing sound in the affected ear
• Dizziness or balance problems

Symptoms in children

• Delayed speech or language development
• Not reacting when called from one side
• Turning the head to hear better
• Difficulty at school or with following instructions

Symptoms in older adults

• Thinking that other people are mumbling
• Trouble hearing on the telephone with one ear
• Feeling left out in group conversations
• Needing extra effort to hear, leading to tiredness

Causes

Main causes

• Wax buildup that blocks the ear canal
• Ear infection or fluid behind the eardrum
• Damage to the inner ear from loud noise or a viral infection
• Head or ear injury
• Changes in air pressure, such as on an airplane or while diving
• Some medicines that can harm the ear (ask your doctor if you are concerned)

Risk factors

• Being over 60 years old
• Frequent exposure to loud noise
• Having diabetes, high blood pressure, or heart disease
• A family history of hearing loss
• Smoking

When to see a doctor

See a doctor urgently if:

• Sudden hearing loss – this is a medical emergency and you should see a doctor or go to an emergency care center the same day
• Hearing loss with severe pain, discharge, or bleeding from the ear
• Hearing loss after a fall or injury to the head

Book a routine appointment if:

• If you notice gradual hearing loss in one ear that is not improving
• If family or friends comment that you seem to not hear well
• If you have persistent ringing in one ear

Diagnosis

A doctor will ask about your symptoms, examine your ear, and do one or more simple hearing tests. They may also check your nose and throat to look for related problems.

Tests that may be done

• Otoscopy – looking into your ear with a special light
• Tuning fork tests – to see how well you hear different sounds
• Audiometry – wearing headphones and pressing a button when you hear beeps
• Tympanometry – measuring how your eardrum moves

What to expect at your appointment

The tests are painless and usually take less than an hour. Your doctor will explain the results and, if needed, refer you to an ear, nose, and throat (ENT) specialist.

Treatment

Treatment depends on what is causing your hearing loss. For many people, it improves with simple steps or by treating the underlying issue. For others, hearing aids or other assistive devices can help you hear better.

Self-care at home

• Keep your ears dry and avoid putting anything inside them, including cotton swabs
• Use ear protection, such as earplugs, in noisy places
• Tell your doctor about any medicines you take that could affect hearing
• If earwax is a cause, use softening drops or have it removed by a professional – never try to scrape it out yourself

Medical treatments

Your doctor may suggest medicines such as antibiotics for an infection or steroids to reduce inflammation, depending on the cause. Always take any prescription exactly as your doctor advises, and never share medicines with others. Your doctor will choose the safest option for you.

When is surgery considered?

In rare cases, surgery may be needed – for example, to drain fluid, repair a damaged bone, or place a hearing implant. Your ENT specialist will discuss this option with you if it could help.

Living with this condition

You can adjust by sitting closer to people, facing them when they speak, and asking others to get your attention before talking. In meetings or classrooms, ask for written notes or choose a quiet place for conversations.

Lifestyle tips

• Use hearing protection in loud environments
• Reduce background noise when you need to listen carefully
• Tell friends and family about your hearing – it helps them support you
• Try assistive devices like hearing loops or phone amplifiers

Diet and exercise

A balanced diet and regular exercise support your overall health, including your ears. Protect your ears from loud noise, and keep conditions like high blood pressure and diabetes well managed if you have them.

Mental health and emotional wellbeing

Hearing loss in one ear can make social situations tiring and sometimes frustrating. It is normal to feel sad, anxious, or isolated. Talk to your doctor or a counselor if these feelings affect your mood or daily life. If you are in distress, reach out to a mental health crisis line in your area.

Prevention

Not all cases can be prevented, but you can reduce your risk by protecting your ears from loud noise, treating ear infections quickly, and avoiding putting objects in your ears. If you experience sudden hearing loss, seek care right away.

Vaccines

Vaccines can help prevent some infections, like the flu or meningitis, that may cause hearing problems. Ask your doctor about recommended vaccinations for your age and health.

Screening programmes

Newborns in many countries receive routine hearing screening. Adults who work in noisy jobs should have regular hearing checks. If you are over 60, consider asking for a hearing test even if you think your hearing is fine.

Complications

If left untreated

• Persistent hearing loss that affects daily life
• Trouble communicating, which can lead to feeling isolated
• Balance problems and falls, especially in older adults
• Delayed speech and learning in children if not treated early

Long-term outlook

With the right help, most people with hearing loss in one ear manage very well. Starting treatment early – especially for sudden hearing loss – gives the best chance of recovery. Many people continue living full and active lives with hearing aids, assistive devices, and support from their healthcare team.
