    Speaker interference

    Advertisement



    Okay stackers, this is not a world turning issue, it just annoys me.

    Since getting my Pearl I have noticed that anytime it is anywhere near any type of speaker, there is a random intemittent buzzing. This happens everywhere. My computer upstairs, laptop downstairs, computers at work, televisions. Anyone know why that is and if there is something I can / nedd to do to correct this?

    as long as i have used GSM service, i have always got some sort of feed back when ANY of my phones have been near speakers. i know that doesn't really solve anything for you other than to say it's normal. UNLESS i have been living in the dark all these years and there is some way to correct it.

    Re: Speaker interference

    I can explain why....

    GSM uses what is known as time division multiplexing as does Nextel. Verizon or Sprint uses CDMA which is frequency multiplexing.

    Frequency multiplexing, allows constant communication with the tower.

    The noise all stems from you can only have so many phones talking to the tower at the same time. Using Time division multiplexing your phone as an assigned millisecond it can talk to the tower and has a window of use. So when your phone bursts its data, it does so "fast and loud". Since it is a cyclical time it eminates sine waves which will interfere with non-shielded speakers. This will be a problem as long as your speakers are not magnetically shieled.


    I hope I didn't get too technical, and hope this explains it.

    Thank you Tom, and when my 14 y/o nephew stop by later I'll ask him what you just said.

    Seriously, thanks everyone. As I said it's not that big of a deal I was just curious
