What is tinnitus?
Tinnitus is the sensation of hearing sounds that aren’t caused by an external source. Many people describe it as a ringing in the ears, but it can also sound like buzzing, hissing, clicking, or whooshing. These sounds can be soft or loud, constant or occasional, and may be heard in one or both ears.
For most, tinnitus is a symptom rather than a standalone condition. It's commonly associated with hearing loss, aging, or noise exposure. While it doesn’t cause hearing loss, the two often go hand in hand, and tinnitus can significantly affect concentration, sleep, and quality of life.
Tinnitus can affect people of all ages, but it's particularly common in older adults. According to research, over 15% of the global population experiences tinnitus at some point. The emotional impact of tinnitus can vary widely, from a mild nuisance to a severe disruption of daily life.
Understanding the potential causes and management strategies can make a major difference for those affected.

Common causes of tinnitus
Tinnitus has a wide range of causes, and in many cases, more than one factor may be involved. The most common include:
Age-related hearing loss
As we age, delicate cells in the inner ear (called hair cells) can naturally break down. This can reduce the brain's stimulation from sound, which may trigger tinnitus as the brain attempts to compensate for the missing signals.
Loud noise exposure
Frequent exposure to loud environments, such as concerts, construction sites, or using headphones at high volumes, can damage the inner ear and lead to both hearing loss and tinnitus. This kind of damage can be sudden or build up over time.
Earwax blockages or infections
Excessive earwax or an ear infection can cause pressure to build up in the ear canal, leading to a change in how you perceive sound. In some cases, treating the blockage can help relieve the tinnitus.
Medications
Certain medications are known to trigger or worsen tinnitus, particularly at higher doses. These include some antibiotics, antidepressants, cancer drugs, and nonsteroidal anti-inflammatory drugs (NSAIDs). In many cases, the tinnitus resolves once the medication is discontinued.
Underlying health conditions
Chronic conditions such as high blood pressure, diabetes, thyroid issues, and autoimmune diseases can affect the auditory system. Tinnitus may also be associated with temporomandibular joint (TMJ) disorders, head and neck injuries, or circulatory problems.
In rarer cases, tumors such as acoustic neuromas or abnormalities in blood vessels can also trigger tinnitus. Identifying these less common causes often requires thorough diagnostic testing.
Types of tinnitus
Tinnitus generally falls into two categories:
Subjective tinnitus
This is the most common type of tinnitus, where only the person experiencing it can hear the noise. It is typically caused by problems within the auditory system, such as damage to the inner ear (cochlea), auditory nerve, or related brain pathways. These disruptions may lead the brain to misinterpret the lack of external sound input and generate internal noise, such as ringing, hissing, or buzzing.
Subjective tinnitus is often associated with age-related hearing loss or prolonged exposure to loud sounds. Stress, anxiety, and fatigue can also make the perception of these phantom sounds more noticeable. While it can be persistent, many people find relief through hearing aids, sound therapy, or cognitive behavioral techniques.
Objective tinnitus
This rare form of tinnitus can actually be heard by a doctor during an examination. It is usually caused by a physical issue such as a blood vessel disorder or muscle spasm.
Some individuals may also experience pulsatile tinnitus, where the sound aligns with their heartbeat. This can be a sign of a vascular issue and should be evaluated by a doctor.
Tinnitus can also be intermittent or constant. Intermittent tinnitus may only be noticed in quiet environments or under certain physical conditions. Constant tinnitus can become more intrusive and difficult to ignore, particularly at night.
How tinnitus is diagnosed
Diagnosing tinnitus typically involves a comprehensive exam by a hearing professional or audiologist. They may:
-
Examine your ears for signs of infection or blockages
-
Conduct hearing tests to determine if hearing loss is present
-
Ask about your medical history and medications
In some cases, imaging tests such as MRIs or CT scans may be used to rule out structural issues or tumors. If TMJ issues are suspected, a referral to a dentist or jaw specialist may be recommended.
You may also be asked to describe the sound you're hearing, when it occurs, and how it affects your daily life. This information can help specialists tailor a treatment approach to your specific needs.
Can tinnitus go away on its own?
Sometimes. Temporary tinnitus can occur after exposure to loud noise (like a concert) and may resolve within a few hours or days. However, persistent tinnitus is often linked to long-term hearing damage or an underlying condition, and may not go away without targeted treatment.
In cases where tinnitus is caused by earwax buildup or medication side effects, treating the root cause can often make the tinnitus disappear. But when it's related to age or chronic hearing damage, ongoing management may be necessary.
Treatment options for tinnitus
There is no universal cure for tinnitus, but many treatments can reduce its impact and make it more manageable.
Hearing aids and sound therapy
For those with hearing loss, hearing aids can amplify external sounds and make the internal ringing less noticeable. Sound therapy devices or white noise machines may also help mask tinnitus, especially in quiet settings.
Some people benefit from in-ear noise generators or apps that create soothing background sounds. Over time, the brain can learn to tune out the tinnitus when it’s consistently masked by these external noises.
Cognitive behavioral therapy (CBT)
CBT is a type of counseling that helps people reframe how they respond to tinnitus. It doesn’t eliminate the sound but can reduce its emotional toll and improve sleep, focus, and stress levels.
Group therapy, mindfulness techniques, and relaxation exercises are also commonly recommended to manage the psychological impact of tinnitus.
Lifestyle changes
Identifying and avoiding triggers (such as caffeine, loud noises, and stress) can make a difference. Maintaining a healthy cardiovascular system through diet and exercise may also help reduce symptoms.
Getting enough sleep, reducing alcohol consumption, and managing anxiety can help minimize flare-ups. Even moderate adjustments in daily habits can contribute to long-term relief.
Medical approaches
When tinnitus is linked to a medical condition, treating the root issue can sometimes resolve the symptoms. This may include adjusting medications or managing underlying conditions like hypertension or TMJ disorders.
In cases of structural abnormalities, surgical options may be discussed, though they are rare and depend heavily on individual diagnosis.
Living with tinnitus
Tinnitus can be frustrating, but it doesn’t have to control your life. Many people find that once they understand their condition and explore effective management strategies, it becomes less disruptive. Establishing routines, using soothing background noise, and seeking support from professionals can make daily life much easier.
Support groups, online communities, and professional counseling are valuable tools for coping with tinnitus long-term. These resources provide emotional validation and practical advice from others who understand the experience firsthand.
Prevention and hearing protection tips
You can reduce your risk of developing tinnitus or prevent it from worsening by protecting your hearing. This includes:
-
Using earplugs or earmuffs in loud environments
-
Turning down the volume on headphones and speakers
-
Taking breaks from noisy settings
-
Scheduling regular hearing check-ups, especially if you're over 60 or work in a high-noise industry
-
Avoiding prolonged exposure to noise in recreational activities such as concerts, shooting ranges, or motorsports
Custom hearing protection devices, often available through audiologists, can offer enhanced comfort and noise reduction tailored to your specific needs.
