BBs and pink noise

Masking binaural beats with pink sound does not decrease their effectiveness. Note: Pink sound is mixed with Hemi-Sync's binaural beats to provide a sensory integration link with out-of-body experiences. Research has shown that noise does not obscure the initial perception of binaural beats and it provides a ganzfeld environment conducive to altering states of consciousness.
