The signals were then resynthesized into the range of human hearing by scaling them upward by 57 and 58 octaves above their true pitch. Another way to put this is that they are being heard 144 quadrillion and 288 quadrillion times higher than their original frequency
This is like an “AksHuaLLy there is sound” explanation. What, one oscillation per human lifetime, or longer? I’ll do the math later
ETA: closer to 18 million years per oscillation
