Pretty much all psychosomatic and physical effect research in sound has been done already and most is available on the net.
I got a few papers from the net about infra and ultra-sound and the various moods related to certain frequencies, but most of these frequencies are out of the range of conventional soundsystems. The stuff I found that could be used I put into my last PA ,Facing Choronzon, which was an experiment with psychosomatics, audio sigils, occult techniques and nlp. When I wasplaying it live I did notice some of the intended effects working, but you are heavily reliant on running through a properly set up sound system for this kind of stuff to be effective.
As for surround sound in clubs, we barely have clubs set up properly for stereo, let alone 5.1.
I`m not sure Audio spotlighting has much of an application musically outside of the art gallery (except for advertising) but it is pretty interesting tech.
There`s a lot of this kind of experimentation going on in contemporary composition and "art" music, but not techno.
