hello all. sorry for the frequent questions! i'm just trying to get my thoughts organized regarding tinnitus and this forum is proving to be extremely valuable. thank you so much to everyone! so i've talked with some people (both in the open forums and in some private conversations) that report their tinnitus had a "delayed onset" or even a "very slow onset" after their noise exposure. so, i thought i would open the question up to a broader audience by posting a specific thread for it on the board... @erik even turned me on to this great link http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2686891/ : "It is hypothesized that a reduction in auditory nerve input leads to disinhibition of the DCN and an increase in spontaneous activity in the central auditory system, which manifests as tinnitus.49This mechanism could explain the temporary ringing sensation that can follow exposure to loud sound.50The plastic readjustments in the DCN are slow and lead to tinnitus with a delayed onset. IHC damage prevents hyperactivity in the DCN" so, here's the question... Q: for those with noise induced tinnitus, how long after the noise insult did your T start? also, what was the speed of onset? as i've noted in other threads, for me personally, there was a solid week or two between the time of my noise exposure and the time of my T onset.
