Ultrasound - sound waves having a frequency higher than the ones perceived by the human ear, usually, by ultrasound, understand frequencies above 20,000 hertz. A person simply does not hear such ultrasonic waves.
An inaudible sound can control a person's behavior. By the way, it is used to disperse crowds of demonstrators. And, they say, it helps better watering machines and tear gas.
If the impact of infrasound will be accompanied by some text, it is quite possible to instill in the person installations that are contrary to his own, in other words to hypnotize a person at his discretion. And the person will not notice that some influences or hypnosis have been applied to him, and he will consider these settings (the suggestion program) his own. This tactic has long been used with success in secret laboratories.
