The sound and acoustic play equipment have a surprising and pleasing effect for young and old.  Children enjoy and have fun creating tones and noises by their own movements.  Different kinds of movement, such as jumping, pulling, running, rotating, balancing, or compressing, cause the game elements to be resounded.  For older people as well as for the children with limited abilities, is more often about enticing them out of their inactive attitude and providing them with the opportunity of self-determined action.  The equipment with acoustic effects can aid in this task delivering therapeutically effects.
