Mobbing: Sound Technologies (hypersonic sound) Sound technologies can be used by organized crime for criminal psychological harassment by targeting a victim 24/7 through constant interrogation and other psychological technologies that are destructive to the brain such as provocation, which depletes the victim, inducing anger or hate through torture which inflames the brain, and more specifically sleep deprivation, which prevents recovery and repair of the brain, and leads to acid-base imbalance or acidic blood pH, which causes more damage to the brain, and can lead to stroke. Homelessness could be linked to the use of this technology and victims who may try to "escape" sleep deprivation by sleeping on a public bench or park when targeted by organized crime with sound technology such as hypersonic sound.
