1. Both use the same musical information to create the experience.
2. The subwoofer generally is a low frequency audio driver that is complementarily to speakers and is designed to produce audio (sound in the air). The SO SoundHearts are a completely different addition to an audio sound system because they add tactile (what you feel) excitement from the music/sound.
3. The range of the full system can be shown by the graph below.
4. A Subwoofer is designed to deliver music via the air (at the speed of sound in air) versus via mass (at the speed of sound in water). SO with a subwoofer you have to turn up the volume very high in order to feel the low vibrations. This is not healthy for the ears or for the autonomic nervous system of body/mind long term.

Introducing Acoustic Resonance Technology (ART) to augment the pure listening experience supports a sensory integration experience. We increase the bandwidth (frequency range) for receiving the musical information in a more comprehensive way. There are several other key things to be aware of in appreciating this as an augmentation to just listening to music:

• Numerous holistic healthcare studies indicate that as we become more aware of the sensing and feeling state of the body/mind, we naturally strengthen our immune system. Energy follows awareness. This is the basis of accupuncture, massage, carnail sacral practices as well as somatic therapy.
• In alignment with this is research around pain control. For example a study known as “The Theory of Pain Control” initially proposed in 1965 by Melzack & Wall (see link to articles). This research basically demonstrates that when one gently touches the body through massage or subtle vibrations we stimulate a neurological communication to the brain to stimulate the pleasure response of the body/mind. This actually buffers the pain response and begins to entrain the body back into a more balanced state of health and well being.
• Research conducted by NASA (see link to article) In short, it shows that standing or sitting on a vibration platform can help mitigate bone loss, as well as increase the flow of oxygen through the bones. As the bones begin to resonate, muscles and ligaments surrounding the bones begin to relax. Stress is reduced, flexibility and range of motion improves.
