If you mean the audible sizzle coming from the bed, it is not an electrical noise ;) . The bed behaves like a loudspeaker and the 30Hz PWM responsible for switching heating on and off makes this sizzle. Right now we are working on a silent solution to this problem, we hope to have this fixed in FW 3.8.0.
