In the case of HD Radio, one man's noise is another man's very nice signal. Depends on the receiver you're using. For the digital listener, the analog signals are the "noise" -grin- There are many sources of noise but the ones you listed are mostly beyond our control. I was getting at noise generated right in your house or neighbors houses. You can exert some control over that by choosing products that are less noisy, filtering, etc. I recently returned some very radio-noisy motion sensor light units I bought at Home Depot. The clerk as astonished that (A) I would return something because of radio interference, and (B) that a light fixture can cause radio interference. She probably didn't believe me anyway.
