Variable dimensions.
Tunnel here: L x W x H = 13.75 x 1.55 x 2.50 m
Spotlights are mounted on both walls of the tunnel just above eye level.
The light and the electronically generated tone are interrelated.
Three sequences alternate rhythmically:
– A very deep sinus tone (60 Hz) in utter darkness. The tone thus generated
makes the tunnel vibrate slightly and spreads up from the floor throughout the body.
– A very high frequency sinus tone (12,000 Hz) with glaring light and heat.
It can only be perceived in the head.
– Quiet and darkness.
The tone frequencies, which cannot be located in the room, hover on the limits of acoustic perception.
