[sci.electronics] noise eliminators

I've heard that there are plans or kits available for little boxes
that drown out noise like dogs barking, lawnmowers, noisy stereos, etc
while you are trying to sleep. I know that you can buy the actual
boxes but they cost about $90.00. It seems to me that there should be
plans or kits to build them for a fraction of the cost. If anyone can
point me in the right direction, I'd be very grateful. Thanks in
advance.
