Why do people with tinnitus hear what they hear?

People with tinnitus perceive sounds, such as ringing or buzzing, due to abnormal activity in the auditory system, often following hearing loss or damage to the inner ear. This can lead to the brain misinterpreting neural signals, creating the perception of sound even in the absence of external noise. Factors like stress, exposure to loud noises, and certain medical conditions can exacerbate the experience of tinnitus. Essentially, tinnitus is the brain's response to changes in auditory input rather than an actual sound occurring in the environment.
