Tinnitus—that constant, persistent ringing in the ear—is very common: according to the Tinnitus League, it affects about 1.5 million people in Germany. However, the exact cause of tinnitus remains a mystery to modern medicine. What we do know is that several factors interact to cause this condition.
To understand how tinnitus develops, let's take a look at the various causes that can lead to tinnitus.
First sound: A soft whistle or hiss
Tinnitus often begins with a soft sound in the ear that is barely noticeable at first. It can be a high-pitched whistling, a hissing, buzzing, or crackling sound that is only noticed during quiet moments. At first, it may be only sporadic and not very bothersome, but over time it can occur more frequently and become louder.
What makes this special is that it is a sound that cannot be heard from the outside—it is purely subjective and is produced inside the ear.
What causes tinnitus?
There are various causes of tinnitus. The most common are:
- Noise: Long-term exposure to noise, such as loud music or machinery, can damage the sensitive inner ear and cause tinnitus.
- Stress: Psychological stress affects the nervous system and can heighten the perception of sounds.
- Hearing loss: When the ear can’t hear as well, the brain tries to compensate for the missing sounds—and “invents” sounds that aren’t there.
Other possible causes of tinnitus:
- Otosclerosis
- Sudden hearing loss
- Traumatic Brain Injury
- Acoustic neuroma
- Meniere's disease
- Inner ear toxicity
- Cervical Spine Dysfunction
- Craniomandibular dysfunction (CMD)
- Bruxism (teeth grinding)
- Changes in blood vessels
- Chronic middle ear disorders
What role does the brain play in tinnitus?
Tinnitus does not originate in the ear, but in the brain. The ear converts sound waves into signals that are processed by the brain. When a condition such as hearing loss disrupts the balance in the system, nerve cells in the brain fire differently and “invent” sounds that aren’t actually there. This results in a constant noise that is perceived as an internal hissing or buzzing sound.
Current research describes this process as a “neural misfire” in the brain, in which acoustic signals are not processed correctly.

His journey back to good hearing is as unique as it is fascinating. Learn more in the interview“When it comes to hearing loss, there’s not a single good reason to wait.”
Tinnitus as a Psychological Challenge
In addition to physical causes of tinnitus, psychological factors such as anxiety, depression, and sleep disorders also play a major role in the development and intensification of tinnitus. These can amplify the perception of the sound and significantly impair the quality of life of those affected. Negative thoughts and constantly focusing on the tinnitus further intensify the distressing sensation.
And: The more people with tinnitus think about it, the more intensely they perceive it. This is because the brain amplifies the sound the more attention it receives—and the more present it is, the more people with tinnitus think about it.
Taking action early brings relief
Tinnitus does not have to be permanent. The sooner the causes are identified and treated, the better the chances of finding relief. Modern therapies such as Tinnitus Retraining Therapy (TRT) or cognitive behavioral therapy offer help and can reduce tinnitus.
