STOP THE NOISE!

[XLR99]

For what it's worth, the vast majority of the noise from small aircraft comes from the prop(s).

This does bring up the point that pilots can proactively try to minimize their noise footprint. There's a certain Bo pilot who will always slam the prop into high RPM 5 miles out and overfly the entire city at pattern altitude making a bunch of unnecessary noise. I actually LIKE airplane noise, and it aggravates me because I see the people looking up with the same look of disgust I use when a bunch of pirates ride by with straight pipes.
