URBANJOY
- BRINGING JOY TO URBAN SOCIETY
URBANJOY has developed the
innovative and challenging sports- and playground equipment
named WHISPERHILL.
The WHISPERHILL consists of
two opposite parabolas in the form of half a dish and the size of a
football goal. If you whisper in the focus of the parabola, the sound
will be reflected to the opposite parabola. Here you can even hear a
smallest whisper so clearly, as if you have headphones on!
This
is due to the property of the parabola: any sound from the focal point
reflects in a straight line to the
opposite parabola. This is why you can communicate
over a distance of tens to hundreds of meters.
Against this parabolic wall a mound is raised
covered with grass or EPDM-rubber.
The
WHISPERHILL invites
you to communicate, wonder about physics, play football, climb and
invites you to create your own game.
