Tinnitus is a common auditory symptom characterized by the perception of sounds in the absence of any external auditory stimulation. According to the Larousse dictionary, it is an "auditory sensation perceived in the absence of any external stimulation to the body." Unlike some auditory conditions caused by sounds of external origin (audible sounds, infra- or ultrasounds, electromagnetic fields), tinnitus manifests independently of the sound environment. It is therefore a sign of an underlying condition but is not a disease itself.
Symptoms
People suffering from tinnitus often describe a variety of internal sounds, such as whistling, buzzing, pulsing, or clicking. While it is common to briefly hear these sounds in extremely quiet environments, these noises become problematic when they persist in normal sound settings, causing annoyance and discomfort. Tinnitus can be perceived consistently or intermittently, and its intensity varies from person to person.
Possible Causes
Two main types of tinnitus are distinguished: objective tinnitus and subjective tinnitus. Objective tinnitus, which is rarer, can be heard or recorded during a medical examination. They are often caused by vascular abnormalities, requiring appropriate radiological examinations, or by underlying neurological conditions. In contrast, subjective tinnitus, much more common, is only perceived by the patient. Their mechanism is more complex and shares similarities with pain syndromes felt after an amputation.
Treatments and Management
There is no universal treatment to eliminate tinnitus, but several strategies can help alleviate its effects. Treatment varies depending on the identified cause. In some cases, medications are prescribed to treat a specific condition, such as an infection or vascular anomaly. Patients with hearing loss may benefit from hearing aids, which help not only to improve hearing but also to reduce the perception of tinnitus.
One of the most effective methods is the use of white noise generators to mask tinnitus. Tinnitus Retraining Therapy (TRT), which combines sound enrichment and the use of noise generators over 12 to 18 months, is often accompanied by counseling sessions to help the patient better manage their perception of these internal sounds. Additionally, cognitive-behavioral therapies (CBT) prove effective in managing the emotional and psychological reactions associated with tinnitus, notably by reducing the stress and anxiety they can cause.
Learning to Live with Tinnitus
Chronic tinnitus can be disabling, but management is based on a personalized approach. It is essential to understand the phenomenon to reduce anxiety related to this symptom. Enriching the sound environment, for example by using sound generators or soothing sounds, helps divert attention from tinnitus. Relaxation techniques, such as meditation or yoga practice, are also recommended to reduce stress, a factor that exacerbates tinnitus.
