The most advanced approach to total wellness through concurrent sound and light. Nine Solfeggio tones paired with nine color fields, plus binaural programs.
Nine Solfeggio tones, nine color fields, one practice. Tap a tile and sound, colored light and gentle haptic pulses run together for 3, 6 or 9 minutes at the pulse rate you choose.
Photo Acoustic Therapy is based on the work of Dr. Leonard G. Horowitz, a pioneer in the use of colored light and sound for personal wellness. It is a daily practice for relaxation, renewal and rejuvenation of body, mind and spirit.
