Noticed something interesting about my microphone today and can't stop thinking about it.
So there's always been this humming noise with my microphone (I can clearly hear it since I am using headphones), but I've never really thought about it. Now suddenly today my foot touched the metal casing of another PC, and the humming stopped. I was confused, so I tried different things:
Touching the metal case of that PC would minimize the humming.
Touching an USB port on my PC (metal) would also minimize it.
Touching a metal piece on a radiator in my room would amplify the humming sound.
And then I noticed something even more strange - when the tip of the microphone (where you're supposed to speak in) was NOT pointed towards me, then me touching the USB port, the metal case of the PC or the radiator did NOT have as much effect as when it WAS pointed towards me.
Apparently this is supposed to be ground looping sound, but I don't really understand what's going on here.
Would someone care to explain?
Thanks in advance,
