FM radio is inherently less sensitive to natural noise ... not immune
but significantly less sensitive ... than AM radio is.
An Fm Receiver.
XM radio does not have static interference. It's a digital signal, so you'll either get a crystal-clear sound or none at all.
my radio has static in it an i put another one in it an it still has static in it to.
Could be a wire crossing in the speakers, the radio itself might be bad. Does it do it all the time? Speakers might be blown. Or, your antenna lead is not plugged into the rear of the radio. Is it radio static, or does it have static on cd/tape as well?
Interferometry
You should not experience any static with your Sirius Radio if it is properly installed.
FM raidio. because it seems to have a inherent nose reduction capability not possible with AM.

Probably localised interference from a nearby source. Many electrical motors don't have suppressors fitted - when they run, they send out interference which can be picked up by any radio or telephone.
Radio static letters : "EMI"
AM radios are based on the principle of sound waves being sent through the air. If the AM radio station has static, you may wish to move to a new area where reception is better.
Sometimes a resistor is installed in spark plug wire as a supressor to reduce radio static interference

There was interference with the radio signal.
A broadcast receiver is a radio that receives broadcasts from commercial radio stations.
This is usually on the AM band waves. It is cause by interference from the fuel pump. When the car is off, the fuel pump is not running.
The first radios were untuned radio telegraphs that broadcast a burst of radio static generated by a powerful arc when keyed. The receiver used a device called a coherer to detect this burst of radio static and activate the telegraph sounder. It took the development of vacuum tube triodes to modulate radio waves with voice and music as well as provide tunable radios. Armstrong invented improved receivers like the Superheterodyne and improved modulation techniques like FM that rejected static and noise.
If the interference is powerful enough, and if it's neare nough to frequencies that you're trying to use for some application like cell phone or AM radio, and if your receiver isn't able to reject it, then yes. That's why it's called "interference".
