SOUNDS AND SILENCE
❶
VOICE DETECTOR
Connect the SOUND BLOC
to the other blocks as shown.
Speak normally and see the
lights change. Experiment
with talking loudly and
softly, near and far, to
see how little or how
much noise you need
to trigger the lights.
❷
SOUND GUARD
Put the Logiblocs together as shown
and hide them beside a door or inside
a cupboard. Put the BLEEP as far
away from the SOUND BLOC as
possible to prevent feedback.
Feedback happens when the sound of the
BLEEP goes straight back into the SOUND
BLOC so that the system never stops!
You could try using a book or a cushion
placed between the BLEEP and the
SOUND BLOC to stop feedback if it
happens too easily.
