Tinnitus
Tinnitus is the perception of sound when no external source is present. It is a common condition that is estimated to affect up to 20% of the global population1 with as many as 4% reporting they are severely impacted by their tinnitus. In New Zealand, approximately 200,000 Kiwis have debilitating tinnitus2.
Technically speaking, tinnitus is not a condition itself, rather, it is a symptom of an underlying condition. It rarely indicates a serious problem, despite the annoyance. There are things that tend to worsen the perception and there are known risk factors, however, no cure exists.
If you have questions or concerns about tinnitus, it's always worth a visit with your local audiologist.
Symptoms
Tinnitus is defined as hearing sound when there is no known source and although everyone experiences tinnitus differently, there are some common descriptions/symptoms1.
- Ringing
- Buzzing
- Humming
- Roaring
- Hissing
- Cicadas
- Rumbling
- Radio off frequency
- White noise
Causes
No one is exactly sure what causes tinnitus, but there are common correlations with certain things.
The most common cause for tinnitus is damage to the inner hair cells in the cochlea (the organ of hearing). These tiny little cells are situated deep in the inner ear and help send electrical signals to the auditory nerve. It's possible for these cells to bend or break, causing them to send improper signals to the nerve and brain - causing these phantom sounds we call tinnitus.
Hearing loss, other problems with your ears (ear infections or wax blockage), chronic health conditions, and/or other health conditions that affect sensory nerves are possible causes for tinnitus2.

Risk Factors
There are some attributes that may put you at higher risk for developing tinnitus.
- Age: as we age, the sensory cells in our ears age as well. These cells can get damaged or injured over time and can cause undesired neural responses that result in the perception of tinnitus.
- Noise exposure: if you have a history of exposure to loud sound, it's more likely you will develop tinnitus.
- Male: men are more likely to develop tinnitus.
- Heart problems: any health condition that impacts your heart can hurt your ears. People with heart conditions are more likely to have tinnitus.
- Smoking: if you smoke, you are more likely to develop tinnitus.
Associated Conditions
Although tinnitus is not a condition on it's own, it can disrupt day-to-functions. Every person will experience tinnitus differently and the impact on daily activities varies dramatically from one person to the next. Some with tinnitus, may also experience:
- Sleep disturbances
- Mood changes
- Anxiety
- Depression
- Irritability
- Fatigue
- Stress
Diagnosis
The process of diagnosing tinnitus starts with a physical exam of your ears, head, and neck. A solid review of your health history and experience with tinnitus is a critical component to the diagnosis. It is important to be as specific as you can about your tinnitus: when it started, how long you've had it, whether it changes pitch or volume, what ear you hear the tinnitus in, and whether there are any things that seem to make it worse. Your audiologist will also go through a variety of tests to assess your auditory health and tinnitus.
- Otoscopy: a thorough look at your ears through an otoscope will determine if there is any type of blockage.
- Audiological assessment: a full hearing test is important to gather information about your auditory system.
- Tinnitus matching: some audiologists will go through the process of determining the pitch of your tinnitus, the perceived volume of your tinnitus and the level of volume needed to mask your tinnitus.

Treatment
There is no cure for tinnitus; however, there are ways to successfully manage it. Just as every person's experience with tinnitus is unique, so is the treatment. For some, it's as simple as forgetting about it. For others, a combination approach with different methods is best.
You can trust when seeing your local audiologist that you'll receive a unique treatment approach that is right for you.
