The Dreampad operates on the natural principle of ‘bone conduction.’  We all hear ourselves speak in 2 ways – sound waves from our mouth travel through the air and enter our outer ear, and sound vibrations from our voice box travel internally by bone to our inner ear.  (This is why your voice sounds different on a recording: you’re not hearing it with the vibrational resonance you get when you speak).  The Dreampad transducers replicate that natural sound vibration.  As the music travels to your inner ear, it triggers your body’s relaxation response, the parasympathetic nervous system.  This results in a calming effect which is conducive to falling asleep and staying asleep.
