So it’s unlikely that the causes of his stroke were audible 40 years before his death. But it does confirm that you simply don’t hear your nervous system and blood as Cage described. Of course, Cage doesn’t mention that he heard his own breathing, which he also certainly did.Jun 29, 2016 · Semi-anechoic chambers and OATS are the preferred method for almost all radiated emissions testing standards such as the ubiquitous ANSI C63.4 and CISPR 16.
