Walker High-Def Links v. Cell Phone EMI-RFI

This is quite a disturbing problem: Yesterday, while receiving a cell call upstairs, the speakers downstairs came to life and emitted that mysterious clicking sound; and this with the amplification off. We use Innersound Eros plugged directly into the wall socket.

Just was wondering because if a cell phone can cause such a loud disturbance, what might a microwave, laundry machine, or television set be doing to distort the signal.

I have no clue on electromagnetism: I'm an English major.

I too noticed that this same phenomenon occurs near our laptop. I initially happened upon this interference in our tube-based amp/preamp system; however, no such interference was an effect in our Threshold-based solid state setup.

Our phones are both Sprint-Nextel. Thanks guys.
