I am re-reading "Tinnitus Retraining Therapy" by Jastreboff and Haskell. This second time around, I notice how much my understanding of the tinnitus differs from these experts. They make the following statement: "Tinnitus beats with external sounds does not occur". Oh yeah? This seems to happen to me all the time. Once I go into our family room, either the TV or our forced air heating system, sets up this synchronicity with my left ear. I begin hearing "beats" in the vibrations. The vibration in either the TV or the heating system (I think it's the heating system that does it), gets in sync with my tinnitus. This also happens when I walk by the train locomotive in the morning. I start hearing this "wow-wow" effect with my tinnitus. But Jastreboff and Haskell say the following: "Cyclical fluctuations of loudness of perceived sound occurs when two pure tones that are very close in frequency are presented together. The phenomenon is called beating of tones, and the cyclical rate of loudness change equals the difference of the two frequencies. This phenomenon has not been achieved during attempts to produce beating with tonal tinnitus (perceived as being similar to pure tones) an externally applied pure tone." This makes me wonder if I am actually hearing a "somatosound" from the OHC (outer hair cells). The book says that somatosounds differ from tinnitus: "In the case of spontaneous otoacoustic emissions, these can be treated, paradoxically, by giving the patient aspirin (which normally induces tinnitus)...Aspirin attenuates action of OHC, which are responsible for spontaneaous otoacoustic emissions and which are involved in tinnitus." I'm taking an aspirin this morning. Experiment No. 387. Interestingly, my tinnitus began after taking 365 mg aspirin everyday for a couple of months, a year ago. I was also taking Metaprolol, due to an episode of atrial fibrillation. I stopped taking both of these, but the tinnitus has stayed. Every now and then, I hear "whizzers" - which sound like fireworks going off. When that happens I hold onto my seat, like, "what the hell was that?". Obviously, according to these experts, that's a "spontaneous" emmission. But is it possible to have continuous pure tones from OHC emissions?
