"Interference with audio devices

This is a form of RFI, and could be mitigated or eliminated by use of additional shielding and/or bypass capacitors in these audio devices.[citation needed] However, the increased cost of doing so is difficult for a designer to justify.

It is a common occurrence for a nearby GSM handset to induce a "dit, dit di-dit, dit di-dit, dit di-dit" output on PAs, wireless microphones, home stereo systems, televisions, computers, cordless phones, and personal music devices. When these audio devices are in the near field of the GSM handset, the radio signal is strong enough that the solid state amplifiers in the audio chain act as a detector. The clicking noise itself represents the power bursts that carry the TDMA signal. These signals have been known to interfere with other electronic devices, such as car stereos and portable audio players. This also depends on the handsets design, and it's conformance to strict rules, and regulations allocated by the FCC in part 15 of FCC rules and regulation pertaining to interference to electronic devices."

Answer 4

It's called as RF noise.... It is normal becoz ur phone spits out lots of radio waves, which interferes with the magnetic field of your laptop speakers. The only way to stop this is to purchase a phone which doesnt use GSM technology. Within continental US, I guess something like Verizon Wireless would not cause RF Noise in speakers....
