Using sound frequency to boost human health.  Much of the current work is based on the early 70s research of biophysicist Gerald Oster.

Oster showed that when a tone is played in one ear and a slightly different tone is played in the other ear, the difference causes the brain to create a third, internal tone, called a binaural beat.  The theory is that this synchronizes the brain waves in both hemispheres, a process dubbed “brain-wave entrainment”.

Studies have proven that listening to 2 hours of natural sounds a day significantly reduces stress hormones up to 800% and activates 500-600 DNA segments which are known to be responsible for healing and repairing the body.
