Step inside an anechoic chamber and close the door. It’s an eerie sensation, floor to wall, it’s covered in foam and once you’re in, it’s hard to get out.

What’s even creepier is that no one in the outside world could hear even the most blood curdling of screams from anyone stuck inside the chamber.

This got us thinking about our favourite scream scenes from the scary movies of the past.

Our scientists, usually busy testing the acoustic properties of walls, floors and windows for commercial buildings, let us come in for a Halloween special and we brought some of our favourite screams with us to the sound testing chamber.

So which scream shattered the spine tingling frequency charts??? We’ll give you a clue, it wasn’t Arnie or the shrill heard when JAWS attacked… check this out oh, and welcome to the Scream Machine.
