Has anyone considered using a Binaural beat that would change the brain's frequency to either a meditative or deep sleep state? It seems like that would help every product to be more effective than just the sound of trickling water
And if you don't wanna make that mask available, would it still work the same if I got my favorite Binaural beat and combined the ultrasonic subs with it?
