Sound energy is a physical form of energy that moves as a vibrational transmission through matter. Sound loops of a gentle rainfall, waves lapping the shore, an easy breeze through leaves and trees, and a burbling stream (similar to an indoor fountain) are wonderfully calming. You can add other design elements to your home in the form of a sound system, wind chimes, playing musical instruments, drumming, ringing bells, or singing to enhance your home's sound energy.
