ever noticed that when you are working on your P.C with your cellphone in your pocket or on the P.C table (or somewhere very close to the P.C), and when you receive a call or SMS, then before the phone can ring or vibrate, the P.C speakers will start making some kind of a beeping sound.

But however i found that home theatre speakers do not have the same reaction. what is the explanation behind this ?

Not sure but as mobile is working on High frequency that might cause such noise. in Home theater speaker there should be some protection.

The land line phones, if on, also make a sound. In my opinion this has to do with the impedance of the speakers. High power speakers probably do not respond to a low level disturbance as much as the low power speakers in PCs and handsets.

Those amps have much higher ratings.
