I asked this else where but thought i would move it to hear as i'm still trying to understand how multiple noise sources interact. Slightly altered from the original question to add in some more info.
Q. It is raining really heavily in Seattle, enough to get static noise or rating 3, I'm in the shopping district and it's a spam zone of rating 5 Spam noise, and then someone turns on a Jammer (lets say that with rating and distance, it's 3 noise). What is my noise penalty?
Q. The devices releasing the spam are RFID tags, so Device Rating 2, does this mean that with the Static Noise of 3 from the rain, they lose their broadcasting functionality, lowering the spam noise by 5?
