I live in a relatively quiet city, until recently. A flight school

outside are these private plane motor noises.

It is really awful. It is like having a gas powered lawn mower
above me all day long. As one plane leaves, another one takes
its place. I am grateful when the evening comes, or for a rainy
day, so I wont hear them anymore.

Let's get some noise control on these small planes before we all go
crazy.

My glider doesn't make any such noices, and I usually start using a winch
launch (which is pretty quiet). Why are you posting this to a soaring
related group? We're generally not the ones flying these noicy machines.
Maybe you should go complain with the airfield and/or the flightschool, and
see if they can perhaps change the pattern to reduce your problems.
