My electric water flosser disrupts my Bluetooth speaker. There should be no signals coming out of it yet it causes the speaker to static like crazy.

There should be no signals coming out of it yet it causes the speaker to static like crazy. How come?In: Physics AstroFarlen commented March 16, 2020 Electro magnetic waves? Pretty much electrons being emitted at a high enough frequency could somehow interrupt the low grade radio waves coming from your speaker. This would cause the static but would be very rare. Be careful putting that thing close to your head RiskeyBiznu commented March 16, 2020 It isn’t putting out a signal in the way we normally thinking of it.However the machine works pretty similar to an old fashioned radio. I am don’t know what type you have but I am guessing it has a high frequency motor and the electricity in the circuits is enough to produce a signal.For an experements put any other high speed vibrating device in-between the Bluetooth and what’s sending to it and you should see similar interference. mb34i commented March 16, 2020 Motors have a chance to emit radio interference, esp. if they [spark like this](https://www.youtube.com/watch?v=tAOssBQCmCM). Otherwise, electronic circuits could emit unwated radio interference too. westom commented March 16, 2020 Bluetooth operates at Gigahertz. An electric motor will not create frequencies anywhere near Gigahertz.Noise is an electric current with both an incoming and a completely different outgoing path through some part of that bluetooth speaker system. One starts by not trying to fix anything. Start by determining what that incoming and another outgoing path is.For example, operating a bluetooth device from a UPS, that is not connected to AC mains, can identify that as either an incoming or outgoing path. Since power does not come from wall wires, then a noise path is temporarily eliminated (because powered from a UPS that has no AC power connection).Another useful tool is an AM radio when tuned to a distant (noisy) station. Does that radio detect noise from the flosser? If that AM radio detects noise, then some business school graduate removed necessary circuits inside that flosser to increase his bonus. No appliance should make any electrical noise detected by that AM radio.Plenty more paths may explain that noise. But again, do not even consider any recommendation that wants to fix it. The informed always define a problem long before even trying to fix anything. Described are some powerful diagnostic tools. 0 AnswersActiveVotedNewestOldest Register or Login Other Questions You Might Be Interested In:How do people photoshop something out of a picture without there just being a blank space where the ...How do relational databases work?How does wind generate sound?
