gut walls, have expanding foam installed, excellent insulation and
sound proofing, install low noise drywall, can be mounted on noise
reduction holders but you lose a inch or two of room. install new
noise reduction windows, possibly storm shutters, heavy drapes too.

then create some white noise indoors, leave a box fan running, a noise
generator, rain drops, nice noises like that.

see town council have them put up siigns on the highway no jake brakes
between 9 pm and 6 am.

talk to your neighbors the noise must be bugging them too. besides
they may have some creative solutions
