Human ears are extremely complex, and are broken down into three main parts: the inner, middle, and outer ear. Sound waves travel into the outer ear, the disc-like shape of which is designed especially to catch the most sound waves possible. From there, sound waves travel through the middle ear that contains the eardrum, which amplifies soundwave pressure. Finally, the inner ear contains the spiral-shaped 'cochlea' and small hairs that convert sound waves to nerve impulses that are then sent to the brain, creating what we hear as sound. All of EcoSmartDesigns' handmade, pewter charm jewelry designs are proudly made in the USA.
