Interesting. I don't hear a single frequency, I often, but not always, hear two or more. I wasn't aware until today that this is called double tinnitus and is rare. I have TMJ and tinnitus. I always thought my tinnitus was from going to really loud music shows, but now I'm wondering whether it doesn't have multiple causes, which perhaps explains the different frequencies. Does this seem plausible?
