The present invention is directed to a pad and sound transmission system which is adapted to directly transmit audible sound waves into the body at high intensity levels. In one embodiment, the pad is comprised of a padding material and speakers disposed within the padding material. The sound transmission system includes an amplifier, an automatic volume control, and a plurality of input parts. The pad includes a padding material comprised of a layer of highly porous material, a layer made of more dense foam and a stiff foam core in which the speakers are connected. The padding material preferably includes a plurality of openings that form resonant chambers that direct sound-generated vibrations to the shoulder blades, the center of the spine, and the hips of the user. |
