A revolutionary soundproof room for the psychological observation patients, incorporating a one-way vision window, is unveiled

Psychological barrier

A completely soundproof room for the observation of psychological patients’ reactions to drugs and other stimuli, and their behaviour in isolation from their normal surroundings, has been provided at the Barrow Neurological Institute, Phoenix, Arizona. All noise and vibration is excluded. Lighting, temperature and humidity can be precisely controlled. It has one-way vision windows so that the subject can be observed without his knowing, and provision is made for the electronic recording of his reactions.

In this chamber, investigations will be undertaken into the neurological correlation of the senses – sight, hearing and smell – and into the processes of thinking, learning and sleeping, as well as into emotional causes and effects in specific and general instances. Research may include the effects of environment on animal behaviour. This study of mental processes is expected to lead to improved treatment of neurological troubles.

The insulated room is really one room within another with a four-inch air space between the two sets of walls. Each wall is four inches thick and consists of two steel plates with an acoustical filler between them. The floor is similarly made with a rubber mat top cover. In the side walls are two observation windows three-feet square. Entrance is through a soundproofed double door.
