- Cause of Tinnitus
- Exposure to loud music (earphones)
I still don't fully comprehend this condition. I always thought it developed based on the severity of acoustic shock or other condtions leading to damage. Basically, the worse the exposure, the better the chance you have for developing this. A lot of the literature seems to support this. At least... that's how I understand it. The strange thing is that I don't experience this despite exposing myself to really loud music.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4502361/
In the tinnitus models, increased neuronal gain causes spontaneous neuronal activity to be amplified to such a degree that it crosses the perception threshold and thus gives rise to the phantom sound. As such an increase in neuronal gain will also cause amplification of sound-evoked activity, one might speculate that it could lead to a certain degree of hyperacusis. However, the gain increases in the tinnitus models are quite specific in that they first depend on the degree of hearing loss, and increased gain is thus confined to frequencies where hearing loss is present. Second, the gain increases in the tinnitus models amplify both spontaneous as well as evoked neuronal activity. Whether such a specific "tinnitus gain" can also explain the phenotype of hyperacusis seen in patient data remains to be determined.
Do you experience this jon?
