RE: Wireless Router Contamination of Sound?

A while ago, there was a measurement done using a tesla meter. it shows even higher RFI readings from AC wall sockets, from power supply conditioners and from cd players than from a wireless wifi router.

In another word, you got more to worry from audio components within your listening room than from wireless devices from outside of this room.

see link below:

In that earlier post, i suggested some ways to check the effect of RFI on the sound of your audio system. but surprise, surprise, many untrained listeners actually may prefer a sound that is laden with RFI introduced by nearby components!

Another issue you need to be concern about is that, when modem & router plus their switch mode power supplies were plugged into the same power supply grid, there was potential high freq noise feeding back into the grid, degrading the performance of the audio components feeding from the grid. I encounter this problem, despite having my main audio system fed from dedicated ac lines, prioritized and separated from the rest of the house.

So, the question arises, how the hell do we determine that the source of noise pollution is air-borne from wireless devices, or ac lines from noisy switching power supplies?
