Origins of tinnitus (Neurophysiologic Model)
The development of the neurophysiologic model of tinnitus was proposed in the 1980s by Jastreboff. The model proposed that tinnitus results from the abnormal processing of a signal generated in the auditory system. And the limbic system is responsible for the emotional response towards tinnitus. Negative reinforcement (feelings of stress, frustration, fear) enhances the perception of tinnitus and increases the duration in which it is perceived.

This lead to the development of Tinnitus Retraining Therapy, a successful tinnitus management that focuses on retraining and relearning. Once the tinnitus loses its negative meaning, however loud or intrusive it is, it will lessen, and in many cases, the tinnitus may not be heard for long periods of time.
Interesting research on tinnitus
An interesting study done in 1953 revealed that up to 93% of individuals with no tinnitus experience temporary tinnitus when asked to sit in a sound proofed room for a short period of time. Most reported hearing buzzing, ringing sounds like what tinnitus suffers hear. This experiment suggests that tinnitus may be the body’s natural response to changes in our sound environment (silence). The change in sound environment could be due to environmental factors such as sitting in a quiet room or due to physiological changes in our ears, such as hearing loss due to ageing or noise exposure.
Another interesting research shows that only 15% of tinnitus sufferers find tinnitus disturbing and affects their quality of life. The other 85% are not bothered by tinnitus. While the most popular explanation would be that every suffers from varying degrees of tinnitus loudness and duration, the study shows that it actually an individual’s perception of tinnitus that determines whether he or she will find it unpleasant or something of little importance. In fact, some individuals have reported liking their tinnitus, associating the sounds with crickets in a calm forest.
