Hearing Loss in One Ear: Causes, Symptoms, and Treatment Options

 

Introduction: Hearing Loss in One Ear Is More Common Than You Think

Not being able to hear properly from one ear can feel confusing, isolating, and even frightening. Many people notice it suddenly — during a phone call, while watching TV, or when someone speaks from one side. Others experience a gradual decline but dismiss it, assuming it’s temporary or caused by earwax or fatigue. Hearing loss in one ear, also known as unilateral hearing loss or single-sided hearing loss, is far more common than most people realise. In a city like Chennai, where noise exposure, infections, stress, and lifestyle factors are widespread, cases of sudden hearing loss in one ear and long-term single-sided hearing problems are increasingly reported.

At Eljay Hearing Centre, with 50 years of experience and 8 branches across Chennai, many patients come in saying, “I can hear fine — just not from one side.” What they often don’t realise is that hearing from only one ear can affect balance, safety, communication, and mental well-being if left untreated.

This blog explains hearing loss in one ear, its causes, symptoms, and treatment options, and when it’s important to seek professional help.

 

What Is Hearing Loss in One Ear?

Hearing loss in one ear occurs when one ear has reduced or no hearing ability, while the other ear functions normally or near-normally. This condition may be:

  • Sudden or gradual
  • Temporary or permanent
  • Mild to profound

Clinically, it is referred to as:

  • Unilateral hearing loss
  • Single-sided hearing loss
  • Single-sided deafness (SSD) in severe cases

Even mild hearing loss in one ear can significantly impact daily life.

 

Common Symptoms of Hearing Loss in One Ear

Many people don’t notice unilateral hearing loss immediately. Symptoms often become obvious only in certain situations.

Common Signs Include:

  • Difficulty locating where sounds come from
  • Trouble understanding speech in noisy places
  • Needing to turn the “good ear” toward speakers
  • Missing parts of conversations
  • Tinnitus (ringing) in one ear
  • Feeling off-balance or dizzy
  • Fatigue after conversations
  • Increased listening effort

Hearing loss in one ear often becomes more noticeable in social settings, meetings, restaurants, and while driving.

 

Causes of Hearing Loss in One Ear

There are several possible causes, ranging from simple and temporary to serious medical conditions.

1. Sudden Sensorineural Hearing Loss (SSNHL)

Sudden hearing loss in one ear is a medical emergency. It can occur over hours or days and is often accompanied by:

  • Tinnitus in one ear
  • Fullness in the ear
  • Vertigo or dizziness

Possible causes include:

  • Viral infections
  • Circulatory issues
  • Autoimmune conditions
  • Inner ear inflammation

Early treatment significantly improves recovery chances.

 

2. Earwax Blockage or Middle Ear Issues

Temporary unilateral hearing loss can occur due to:

  • Impacted earwax
  • Middle ear infection
  • Fluid buildup

These are usually reversible but still require proper evaluation.

 

3. Inner Ear Problems

The inner ear plays a crucial role in hearing and balance. Damage or dysfunction can lead to hearing loss in one ear, often with:

  • Tinnitus
  • Balance problems
  • Vertigo

Inner ear problems are a leading cause of permanent unilateral hearing loss.

 

4. Noise-Induced Hearing Loss

Exposure to loud sounds — concerts, headphones, machinery, or traffic — can damage hearing unevenly, especially if one ear is more exposed.

This is increasingly seen among:

  • Young adults
  • Industrial workers
  • Frequent headphone users

 

5. Head Injury or Trauma

Accidents or head injuries can damage the auditory pathway on one side, leading to hearing loss in one ear.

 

6. Acoustic Neuroma (Rare but Serious)

A benign tumour affecting the auditory nerve can cause:

  • Progressive hearing loss in one ear
  • Tinnitus
  • Balance problems

Early diagnosis is critical.

 

How Hearing Loss in One Ear Affects Daily Life

Many people underestimate the impact of unilateral hearing loss.

Common Challenges Include:

  • Difficulty understanding speech in noise
  • Increased listening effort and fatigue
  • Poor sound localisation (knowing where sound comes from)
  • Reduced safety awareness (traffic, alarms)
  • Social withdrawal
  • Anxiety and frustration

Over time, untreated hearing loss in one ear can also affect cognitive load and mental health.

 

Hearing Loss in One Ear and Balance Problems

The inner ear controls both hearing and balance. When one side is affected, the brain struggles to integrate signals properly.

This can result in:

  • Unsteadiness
  • Dizziness
  • Increased fall risk
  • Motion sensitivity

At Eljay Hearing Centre, balance assessment is often recommended alongside hearing evaluation for unilateral hearing loss.

 

Diagnosing Hearing Loss in One Ear

Accurate diagnosis is essential for effective treatment.

Diagnostic Tests Include:

  • Comprehensive hearing tests
  • Speech perception testing
  • Middle ear evaluation
  • Inner ear function tests
  • Balance assessments (if needed)

Advanced audiological testing helps determine:

  • Type of hearing loss
  • Severity
  • Best treatment options

 

Treatment Options for Hearing Loss in One Ear

Treatment depends on the cause, severity, and duration.

1. Medical Treatment

  • Used for infections, inflammation, or sudden hearing loss
  • Time-sensitive in many cases

 

2. Hearing Aids for Single-Sided Hearing Loss

Modern hearing technology offers solutions even when only one ear is affected.

Options may include:

  • Advanced digital hearing aids
  • CROS and BiCROS systems
  • Directional microphones for noise control

These devices improve:

  • Speech clarity
  • Awareness of surrounding sounds
  • Confidence in social situations

 

3. Tinnitus Management

If tinnitus in one ear accompanies hearing loss, therapy options may include:

  • Sound therapy
  • Auditory training
  • Counselling-based approaches

 

4. Balance and Auditory Rehabilitation

For patients experiencing dizziness or imbalance:

  • Vestibular rehabilitation
  • Auditory training programmes

These therapies help the brain adapt and compensate effectively.

 

When Should You Seek Help?

You should seek professional evaluation if:

  • Hearing loss in one ear appears suddenly
  • Symptoms persist for more than a few days
  • Tinnitus or dizziness is present
  • Hearing difficulties affect daily life

Early intervention can prevent long-term complications.
