The second stage functions by taking music and creating from it a series of powerful, short duration, random, high frequency pulses. As the child listens to the music, he is attacked by the accompanying pulses. His hypersensitivity causes his brain to react but by the time his brain overcomes the time delay, the pulse is gone. The brain no longer has anything to defend against so it relaxes. Eventually the brain learns it is futile to either try to predict or respond to the short duration stimulus.
