One of the most efficient, cost effective and widely used approaches to reduce the tonal signature of aeronautic engine noise is the so-called liners-structures located in the internal walls of the nacelle (the external structure of the motor) that form an acoustic treatment. In the research project called "Silent Aircraft", funded by FINEP and Embraer S.A. and involving some Brazilian universities, including the Federal University of Santa Catarina (UFSC), an extensive study has been conducted to better understand the behavior of such elements, as well as to predict its effect on engine noise.
Seal the movable part of the window with good gaskets, then cover the whole opening with heavy drapes. Make sure the drapes fit snugly against the wall all the way around. An inexpensive alternative to drapes is a solid piece of 3/4" plywood, gasketed just like a door. This can be hinged to the wall as shutters or in a sliding track, just as long as it fits tightly.

Clearly, a house is a better location than an apartment because you don't have to worry as much about sound traveling through the ceiling or floor.
