Hearing loss or other factors can start a process where the hearing brain tries to compensate for reduced or altered hearing input. Furthermore, our brain has the power to change and adapt, and the hearing brain is no different. Because of this, the adaptation can make the hearing brain overactive, even when no external sound is present. This can contribute to the development of tinnitus.
Unfortunately, it is not just a matter of too much activity. The way the hearing brain processes information can also change. In addition, there are still other changes that have been linked to tinnitus. What makes tinnitus so challenging to treat is that the changes can vary from person to person. In fact, we know that each person can hear a tinnitus sound different from the sound another tinnitus sufferer hears.
