I noticed that every time I suffer temporary tinnitus after going to a very loud concert, the frequency I perceive is identical. I'd put it somewhere around 17KHz, but it's difficult to pin down with any real accuracy due to the dulling effect it has on external sound sources.
Is this frequency constant across all humans? If not, what determines the frequency? Note that I'm only interested in tinnitus caused by exposure to loud sounds, not other types of tinnitus such as idiopathic tinnitus or tinnitus cased as a side-effect of medication.
