Anyone alive here?
Mentioned in PB or PBS, "ringing" / "hypersonic tinnitus". What is this? Any non-speculative clarification? Clearly abnormal compared to the what is claimed to be normal, yet feels by design, natural almost. A marker for some? Chosen? Soldiers? 144k? If a marker, minds that are ready, how to move on to next stage? How to better contribute to the fight? Any insight would be appreciated.
