Special sound setup for outdoors

I have a very difficult situation here.
I have a friend that has a bar outdoors, on the seashore. ight next to it
there are houses. After 12:00 at night he has to turn down the volume in
order not to anoy the neighbours. But then most of the customers will leave
because there is no more fun.
I have looked up and found that he can raise some insulating walls. But
this will destroy the scenery.
Is there a way to setup the speakers, maybe buy special speakers that will
create a descent sound only at the area of the bar, but creating no noise
10-20 meters away, where the houses are?
Thanks

Theoretically (And I will most likely get flamed for this - Hi by the
way I'm new here..) You can playback the reverse of the sound being
played in the spaeaker facing the "stage" with another speaker at a
distance behind it, thus creating a cancelling intertia (that sounds so
much less star trek in Danish) which should, again in theory I have
never tried this in the open, only in enclosed spaces isolate the sound
at the "stage". Naturally this will work poor with bass which has a
tendency to traverse surfaces like the ground rather well. This problem
can be adressed with a programmable DSP which starts say 90 minutes
before "silence" by reducing the bass responce a little bit every
minute, this way the crowd, especially if they have been drinking, won't
notice it. You can do this with the volume too, but they will notice
that sooner.
As I said, this is pure theory, I don't know if it will work in "the
wild" where there are no reflective surfaces, or rather not a complete
shell of them, and also it won't come cheap
Anyway it might not be entirely impropable.
