How far has sound cancellation technology come, for use in a room area? For
example, for a bedroom?

I need some sound cancellation in the bedroom due to street noises outside
while I'm trying to sleep.

I know they have it inside closed headsets for pilots etc, but is the
technology viable yet for a closed room sized area like a bedroom?

I used to know someone who worked for Nelson Mufflers. In addition to
making normal mufflers, they were also getting into sound
cancellation. I had the impression from him that it ws doable, but
expensive and that you could make it as quiet as you wanted, but that
the weight and price went up as you demended more quiet.

In your case, where you just need the cancellation at the head of your
bed (a single person?) that might not be too hard/expensive.

I should add that I believe it is also true that it is easier/cheaper
at lower frequencies (longer wavelengths.)
