Passion Pulse – This sound was specifically created to affect the level of intimacy in your relationship. As with all the other pulse tones in our series, the sound is meant to be ambient (or “in the background”), and is meant for stereo systems with subwoofers and multiple speakers. Results are not expected to occur with the use of headphone, because of the low frequency pulse which affects your “whole body. This pulse tone has been reported to enhance and stimulate both partners in each highly personal encounter. This is only available as CD, because MP3 downloads are inferior acoustically and cannot convey the proper sound.
