Children like to experiment with their voice – in our exhibit Scream they can play high striker with their vocal cords. How loud and also: how quiet can they be? The sound-absorbing roof of the cabin is equipped with solid microphones. A decibel-scale gives a realistic score of one’s voice. From whispers to a rocket launch, children can check out the range of their vocal organs, and they can even gather their friends and hit the jackpot. The glass walls of the cabins are nearly soundproof but leave a clear view of the people inside. So shut the door and shout!
