But, first, a little background. The loudspeakers in your home theater and car are designed to deliver sound into air. Those speakers literally push the air to create the sounds that you hear. This works because air is light and is easy to push. Not so with water. Water is heavy and very hard to push. Just try pushing air with your hand, then try pushing water with your hand. You can feel the difference. This is why traditional speakers cannot work underwater. Clark Synthesis takes a different approach.
Fine instruments, like violins and cellos, use a very different method to produce sound. The beautiful music radiates from the instrument’s surfaces. (For a detailed, technical explanation of how a violin does this, check out this article)
