I am looking at the positive effects of low frequencies in music, predominantly below 50Hz. This involves aural as well as mechanosensations. I am interested in seeing if reinforcing the low frequency content below 50Hz can help produce a more immersive listening experience at lower overall sound pressure levels (particularly when measured using the A weighting scale). Trouser flapping bass.
Please be aware that, historically, religious chants have used low frequencies for production of alpha wave states. In particular I would suggest examining Tibetan Buddhist chant e.g. the Gyoto Monks.
or then there's Charlie Watts and Bill Wyman :-) same thing however.
You might want to investigate how this has worked for cinema - I think the film Earthquake in the 70s was the first film to use frequencies down to 16Hz to give the impression of an earthquake. Probably highly immersive. You might also find some useful material in the various audio conference proceedings such as the Linux Audio Conference or the various surround and ambisonic conferences. You could ask on the SurSound mailing list and someone there would know if there were any papers on this.
