Its not "just noise" when its preventing people from actually sleeping.

I don't think you'd like it if people played deafeningly loud noises outside your bedroom window at all hours of the night every night forever.

I live just uphill of a state highway junction so I get to hear everything accelerating leaving that intersection.

It's really not bad. You don't even notice it after awhile unless it's something that sounds funny like a semi trailer with an out of round tire or like a cluster of motorcyles or a mazda rotary or a nat-gas powered heavy truck.
