In adition to multiple TBI's, longterm noise exposure around jet fighters. Continuous tone, sounds like a jet fighter ideling about 2 blocks away. When i worked in a noise and vibration laboratory, i used some equipment and a sound stage to characterize the noise. It is about 5.1Khz at about 65db. So in a normal environment it fades into the background. But when it gets quiet, the jet sceams in my head. And when i think about it, i hear it. My big trauma involved a jet.
