White Noise Mind Suggestion Combat Experimentation

The "White Noise" is a posthypnotic suggestions sound that Vault 92 used. It was never intended to be used on anything unless needed. Overseer Richard Rubin, however, abused its use and used it as his own mind-control object. He had it broadcasted when all the other vault dwellers slept. Thus making them go insane and killing each other.

Holotapes
There are several holotapes lying around in Vault 92 concerning the mind control project. They give a back story on how things went wrong and the overseer's true intentions.
