| Whenever I'm on the computer, the computer speakers start making all this hissing sounds right before my cell-phone starts to ring. They speakers also make a lot of noise right before getting a text message. Sometimes the speakers start making noise, but my phone doesn't ring. Then after a while I get a call on my homephone or cellphone, and people tell me they were calling me, but got no answer. |
| 1. It has to do with the cellphone signal causing interference with the speakers. Don't worry about it happens to everyone. |
| 2. This is normal, it is called EMI, Electro-Magnetic Interference. Your cell phone is a transmitter, if it too close to your speakers/wiring, the speaker's amplifier is amplifying your cell phone's transmission and you hear it through your speakers as noise. Move your phone away from the computer. |
