Are ferrites effective for cabling?


Good day.  I have several ferrites in varying sizes.  Are they effective for eliminating noise or stray inductance/capacitance?  If so, would they be best utilized on interconnects or speaker cables, or both?  Or, should they not be used at all?  TIA for your thoughts.

Thanks for the more appropriate answer, but kudos to tooblue's sense of humor ;-)  I have a Tice Signature III(b) so I have the noise from the house eliminated, but I'm wondering about what may creep in through the unavoidable tangle of cords that I have unfortunately amassed behind the entertainment center.  I have a couple different sizes and have a couple on cables like the coax coming from the satellite and and an interconnect or two, but wonder if they help with or detract from from the signalling?
@elizabeth , if you fine tune your system a bit maybe with a ferrite or weasel, you would of heard them.
