Let's Talk About Tinnitus

What is it?

Tinnitus is a prevalent hearing disorder that affects a significant portion of the population, estimated to be between 10% and 25% of adults and children. This condition is characterized by the perception of internal sounds, without any external source, making it inaccessible to others. Typically, tinnitus is accompanied by varying degrees of hearing loss and can manifest as a range of sounds, including ringing, buzzing, or roaring.

While some individuals may experience improvement in their tinnitus symptoms over time, for others, it can become chronic and persist for more than three months. The exact cause of tinnitus remains elusive, although extensive medical research indicates that it rarely signifies a severe underlying medical condition and does not typically hinder daily activities. However, it can have a significant impact on a person’s well-being, leading to feelings of anxiety, depression, and affecting mood, sleep, and concentration.

It’s worth noting that tinnitus, sadly, cannot be cured. However, there are effective management strategies available to alleviate symptoms and improve the quality of life for those living with the condition. Sound therapy devices, such as hearing aids, can provide relief by masking the internal sounds and promoting external auditory stimulation. Additionally, behavioral therapies and specific medications can aid in symptom reduction and help individuals cope with the challenges posed by tinnitus.

Adopting a comprehensive approach that combines various treatment modalities tailored to an individual’s needs is crucial in managing tinnitus effectively and restoring a sense of normalcy to daily life. By expanding our understanding of this complex condition and implementing appropriate interventions, we can support those affected by tinnitus to lead fulfilling lives.

What are the symptoms?

Tinnitus is a complex condition characterized by various symptoms that can vary from person to person. People may experience noise perception in different parts of their head, which can manifest as ringing, buzzing, humming, hissing, or squealing sounds. These sounds may fluctuate in volume and pitch, occurring intermittently or persistently. Interestingly, certain somatosensory stimuli like neck-turning, eye movement, or touching can also trigger altered perception of these sounds, known as somatosensory tinnitus.

It is important to note that the sounds experienced in tinnitus are generally subjective, meaning only the individuals themselves can hear them. However, in some cases, objective tinnitus can occur, where the sounds can be detected with a stethoscope. Objective tinnitus usually has a specific underlying cause and may be subject to treatment. By understanding the diverse manifestations of tinnitus and the potential for different treatment approaches, healthcare professionals can provide comprehensive care for individuals affected by this condition.

What causes tinnitus?

Tinnitus, a medical condition whose precise underlying cause remains partially unknown, is characterized by the perception of sound in the absence of external auditory stimuli. While researchers continue to investigate its origins, several factors have been observed to be associated with its occurrence.


  • The most prevalent cause of tinnitus is exposure to loud noise, such as those encountered in high-decibel work environments or during activities like concerts. This association is particularly evident among military veterans, often resulting from exposure to gunfire, machinery noise, and explosive blasts. Nonetheless, it is worth noting that tinnitus can also manifest independently of hearing loss, despite the strong correlation between the two conditions in cases involving age-related hearing decline or noise-induced impairment.


  • Medications, when taken in high dosages, can also contribute to the development of tinnitus. Notable examples include certain antibiotics, anti-cancer drugs, non-steroidal anti-inflammatory drugs (NSAIDs), antimalarial medications, and certain antidepressants. Other potential causes encompass obstructions within the ear canals caused by earwax accumulation or infections, as well as head and neck injuries that inflict structural damage to the auditory system or impair the nerves and brain regions essential for sound processing.


  • Although less common, additional risk factors for tinnitus exist. These include Ménière’s disease, a condition that disrupts inner ear function and subsequently affects hearing; temporomandibular joint disorder (TMJ), a condition characterized by jaw clenching that can impact nearby tissues; vestibular schwannoma, a benign tumor located on the nerve connecting the inner ear to the brain; high blood pressure; atherosclerosis or abnormalities in blood vessel structure affecting blood flow; and certain medical conditions such as diabetes, migraines, thyroid disorders, anemia, and autoimmune disorders like lupus and multiple sclerosis. Moreover, tinnitus can occasionally manifest without any discernible cause.


Further research efforts are necessary to unravel the full complexity of tinnitus and its diverse range of causative factors. Understanding the various elements associated with this condition is crucial for developing effective treatments and strategies to mitigate its impact on affected individuals.

Is there any research being conducted?

Tinnitus research is an active field, with several esteemed research centers, including the National Institutes of Health (NIH) and those funded by the NIDCD, investigating and designing innovative treatment strategies. The condition, rooted in alterations in brain neural networks, has prompted researchers to explore the potential efficacy of magnetic or electrical brain stimulation as a means of treatment.


  • At present, numerous research initiatives are underway to manage tinnitus comprehensively. Cochlear implants, for instance, are being explored as a potential solution for individuals with severe to profound hearing loss, as they can restore functional hearing. Additionally, non-invasive electrical stimulation techniques that suppress tinnitus without causing harm to acoustic hearing are also being investigated. Acoustic stimulation, combined with electric stimulation to the tongue, head, or neck, is being researched as a long-term relief measure for individuals suffering from tinnitus.


  • Preliminary trials on repetitive transcranial magnetic stimulation (rTMS) have yielded mixed results. However, researchers are currently focusing on identifying the optimal coil placement and frequency of patient visits to achieve more effective treatment outcomes. Deep brain stimulation (DBS) is another approach being explored for individuals with movement disorders or neuropsychiatric conditions that have reported a decrease in tinnitus symptoms. While DBS has shown promising results, its invasive nature necessitates further research to determine whether it should be routinely used solely for tinnitus management.


  • In parallel, researchers are also developing medications specifically designed to treat tinnitus. Second-generation versions of a drug that has shown success in reducing tinnitus symptoms in mice are currently being investigated. Genetic associations are also being extensively studied to gain predictive insights and develop preventive measures, screening methods, and effective treatments for age-related hearing impairments and tinnitus. Furthermore, state-of-the-art brain imaging technology and smartphone applications are being deployed to better understand the different types and nuances of tinnitus.


The collective efforts of these research endeavors hold great promise in advancing our knowledge about tinnitus and finding effective ways to manage and alleviate its impact on individuals.
