HAS DOMESTIC MAINS EARTH FAILED AT SOME POINT?
Hello,
It has come to my attention recently - after using computer communications voice software that I can reduce the hum of the microphone recording by lightly touching my pc case. I was always under the impression that the earthing worked in my room. However, I have bypassed the psu earth temporarily simply by connecting a wire from a clamp in the pc case(unpainted surface) to the earth contact hole of the mains socket. This does not reduce the hum at all. However, by touching the case and touching the floor with the other hand I can reduce the hum on the signal. Therefore, is the earthing failing at some point in the house or is there something that I am ignorant of? I can supply any information if you require more detail. thanks goodbye |
