Normal
Can I ask a stupid question?Audible frequencies are 0.00002MHz to 0.02MHz (20Hz to 20000Hz). I get harmonics and how powerful they are.Does RFI many magnitudes of frequencies above our hearing matter? And if so, how?I see that the RFI noise is approaching -60db at some frequencies, which is significant. That’s about 10db below the level one can expect ambient noise to be in a normal household. But we’re talking MHz.Please explain how frequencies above 0.5MHz (500kHz) can audibly interfere with our HiFi system.
