Why do speakers make pulsing noise when a switched on or ringing cell phone is kept near them?
Phones » Why do speakers make pulsing noise when a switched on or ringing cell phone is kept near them? Radiative waves can travel in unguided medium and are generated due to the antenna effect of the circuit. However, when a cell-phone receives or sends a phone call or an SMS, it transmits and receives tokens in a fixed time interval with the base stations. The 4Khz radiative signals from the mobile phones are absorbed by these connecting wires, and thus we hear a pulsing noise. Cure: The absorption of radiative emissions can be reduced by using electromagnetic shields for the entire length of the cable wires connecting the amplifier and the speakers.
Aluminium foil wrapped around the connecting wires can act as a shield. Alternatively, one can reduce the length of the connecting wires to the speakers, thus reducing the antenna length.
Why do diesel internal combustion engines require no spark plug to ignite the fuel unlike petrol engines?

PS : I just have a next door neighbor with some kind of a vent in his attic, I will go out and see if his vent is OFF when the noise if off, will try to analyze daily hour patterns and see if its a business hours related noise, but again, sounds like a bad powerline noise to me? Harro Tesmann, DJ9SA submitted this sample of RFI he experienced on the low end of 10 meters at 28.020 MHz.

Do not leave children unattended in your vehicle and do not let them play with the power windows. When closing the power windows, you should verify they are free of obstructions and make sure that children and pets are not in the proximity of the window openings. When you override the bounce-back feature the window will not reverse if it detects an obstacle.


Pull up the window switch and hold within a few seconds of the window reaching the bounce-back position. You can use the window switches for several minutes after you switch the ignition off or until you open either front door. One can also use wireless speakers, which eliminate the connecting wires and hence the impact of mobile emission is very minimal.
I have not heard it in a few months but last winter it was an almost nightly occurrence.
