There are other alleged uses for binaural beats.
For example, that by using specific frequencies an individual can stimulate certain glands to produce desired hormones. Beta-endorphin has been modulated in studies using alpha-theta brain wave training, and dopamine with binaural beats.
Some people use them for lucid dreaming and even for attempting out-of-body experiences, astral projection, telepathy and psychokinesis. (Note that the scientific consensus is that telepathy and astral projection do not exist, and that out-of body experiences are purely internal mental phenomena. However, the role of alpha-wave activity in lucid dreaming is subject to ongoing research (consult Wikipedia on that matter) Alpha-theta brainwave training has also been used successfully for the treatment of addictions, for the recovery of repressed memories, but as with other techniques this can lead to false memories.
A trial of Delta binaural beat technology over 60 days has shown positive effect on self-reported psychologic measures, especially anxiety. There was significant decrease in trait anxiety, an increase in quality of life, and a decrease in insulin-like growth factor-1 and dopamine and has been successfully trialled to lessen hospital acute pre-operative anxiety.
