Understanding Tinnitus: A Complete Guide to the Ringing in Your Ears

Have you ever experienced a persistent ringing, buzzing, or whistling sound in your ears when there's no external source of noise? If so, you've experienced tinnitus, a condition that affects millions of people worldwide. At our audiology clinic, we frequently encounter patients seeking answers about this sometimes puzzling condition. This comprehensive guide will help you understand everything you need to know about tinnitus, from its causes to treatment options.

What Is Tinnitus?

Tinnitus is the perception of sound in one or both ears when no external sound is present. Often described as "ringing in the ears," tinnitus can actually manifest as various sounds including buzzing, hissing, whistling, clicking, roaring, or humming. The sound can be continuous or intermittent, soft or loud, and can vary in pitch from low to high.

There are two main types of tinnitus:

Subjective Tinnitus: This is the most common form, where only you can hear the sound. It's often related to problems with your outer, middle, or inner ear, or issues with the auditory nerves or brain regions that interpret sound.

Objective Tinnitus: This rare form can actually be heard by your audiologist during an examination. It's usually caused by blood vessel problems, muscle contractions, or inner ear bone conditions.

What Causes Tinnitus?

Understanding the root cause of tinnitus is crucial for effective treatment. The condition can result from various factors:

Hearing Loss

Age-related hearing loss (presbycusis) is one of the most common causes of tinnitus. When hair cells in the inner ear become damaged, they can send random electrical impulses to the brain, which are interpreted as sound.

Noise Exposure

Prolonged exposure to loud sounds, whether from concerts, machinery, firearms, or even headphones at high volumes, can damage the delicate structures of the inner ear, leading to both hearing loss and tinnitus.

Earwax Blockage

Excessive earwax can block the ear canal, causing hearing loss and irritation that triggers tinnitus. This is often one of the more easily treatable causes.

Medical Conditions

Several health conditions can contribute to tinnitus, including:

• High blood pressure
• Cardiovascular disease
• Diabetes
• Thyroid disorders
• Autoimmune diseases
• Temporomandibular joint (TMJ) disorders

Medications

Certain medications are ototoxic, meaning they can damage the ear and cause tinnitus. These include some antibiotics, cancer medications, diuretics, and high doses of aspirin.

Head and Neck Injuries

Trauma to the head or neck can affect the inner ear, hearing nerves, or brain regions responsible for processing sound, potentially resulting in tinnitus.

Who Gets Tinnitus?

Tinnitus can affect anyone, but certain factors increase your risk:

• Age: Adults over 40 are more likely to develop tinnitus
• Gender: Men are slightly more prone to tinnitus than women
• Occupation: Those working in noisy environments face higher risk
• Lifestyle: Regular exposure to loud music or sounds
• Health conditions: Particularly those affecting circulation or hearing

Approximately 15-20% of people experience some form of tinnitus, with about 2% experiencing severe tinnitus that significantly impacts their daily life.

How Is Tinnitus Diagnosed?

If you're experiencing persistent tinnitus, it's important to seek professional evaluation. During your appointment, your audiologist will:

Conduct a Comprehensive Hearing Test

This includes pure-tone audiometry to assess your hearing thresholds across different frequencies, helping identify any hearing loss that might be contributing to your tinnitus.

Review Your Medical History

We'll discuss your symptoms, medical conditions, medications, and exposure to loud sounds to identify potential causes.

Perform a Physical Examination

This may include examining your ears for wax buildup, infections, or structural abnormalities, as well as checking your neck and jaw for issues that might contribute to tinnitus.

Additional Testing

In some cases, we might recommend imaging studies like MRI or CT scans, especially if tinnitus is present in only one ear or accompanied by other neurological symptoms.

Can Tinnitus Be Cured?

While there's currently no universal cure for tinnitus, the good news is that many effective treatment options can significantly reduce its impact on your daily life. The key is finding the right approach for your specific situation.

Treatment Options for Tinnitus

Addressing Underlying Causes

When tinnitus is caused by an underlying condition, treating that condition often reduces or eliminates the tinnitus:

• Removing earwax blockages
• Treating ear infections
• Managing blood pressure
• Adjusting medications that may be causing tinnitus

Sound Therapy

Sound therapy uses external sounds to help mask or reduce the perception of tinnitus:

• White noise machines provide consistent background sound
• Hearing aids amplify environmental sounds, making tinnitus less noticeable
• Tinnitus maskers generate specific sounds to cover tinnitus
• Sound enrichment involves adding pleasant background sounds to your environment

Tinnitus Retraining Therapy (TRT)

TRT combines sound therapy with counselling to help your brain learn to ignore tinnitus sounds. This approach has shown significant success in helping patients adapt to their tinnitus.

Cognitive Behavioural Therapy (CBT)

CBT helps change negative thought patterns and emotional responses to tinnitus, reducing distress and improving quality of life.

Lifestyle Modifications

Simple changes can make a significant difference:

• Stress reduction techniques like meditation or yoga
• Regular exercise to improve circulation
• Limiting caffeine and alcohol
• Ensuring adequate sleep
• Joining support groups for emotional support

Medical Treatments

While no TGA-approved medications specifically treat tinnitus, some may help manage associated symptoms like anxiety, depression, or sleep problems. However, Australia does have a TGA-approved medical device for tinnitus treatment: Lenire. This bimodal neuromodulation device combines sound therapy with tongue stimulation to help reduce tinnitus symptoms. Lenire represents the first device-based treatment option with regulatory approval in Australia for people seeking active tinnitus management.

Can Tinnitus Be Prevented?

While not all forms of tinnitus can be prevented, you can take steps to protect your hearing and reduce your risk:

Protect Your Hearing

• Use ear protection in noisy environments
• Keep the volume down when using headphones or earbuds
• Take breaks from loud environments
• Follow the 60/60 rule: no more than 60% volume for no more than 60 minutes at a time

Maintain Good Health

• Exercise regularly to promote good circulation
• Manage stress levels
• Avoid smoking and limit alcohol consumption
• Keep chronic conditions like diabetes and high blood pressure under control

Practice Good Ear Hygiene

• Don't insert objects into your ears
• Have regular hearing check ups
• Address ear infections promptly

When to See an Audiologist

You should schedule an appointment if you experience:

• Tinnitus that persists for more than a week
• Tinnitus accompanied by hearing loss
• Tinnitus that interferes with your daily activities or sleep
• Sudden onset of tinnitus, especially in one ear
• Tinnitus accompanied by dizziness or balance problems
• Pulsatile tinnitus (rhythmic, like a heartbeat)

Living Well with Tinnitus

Many people with tinnitus lead full, active lives. The key is finding the right combination of treatments and coping strategies that work for you. Remember that tinnitus management is often a gradual process, and what works for one person may not work for another.
