If You Have Earphones, This Interrogation Chamber Video Is A Must See

This play was recorded with two microphones placed in the ears of a dummy head thus being in binaural 3D sound. By listening to the play with stereo earphones in a quiet room you should get the same sound sensation as if you were actually on the set listening. No additional sound effect were added post recording. It was recorded, with permission, in a dismantled nuclear reactor complex 25 metres underground.
