Focalized voices

A wonderful piece of play equipment to demonstrate how sound waves can be focused to enable them to travel over distance. This play equipment is based on two large parabolas that face each other over a distance, one child whispers into one parabola, and despite the surrounding noise of the playground, the whispering can be heard by the other. Without any amplification a clear vocal signal can be transmitted over a large distance.

The large Ø1,800mm stainless steel parabolas have safely rounded edges and are mounted on a robust stainless steel tubular support frame.
