Ultrasonic Sound & Self Development

3 years ago, I picked up an HSS-450 hypersonic sound system from a company called LRADX.

The product is similar to "the audio spotlight" only smaller.

The product was purchased to be used with a marketing gimmick for a client.The marketing campaign never went public, thus the equipment was shelved.

The past 2 years, Ive used the system to play harmless practical jokes on close friends and neighbors.

To make a long story short, I was wondering if this system can be used as a tool for self development.

Other than using the system to broadcast "silent subliminals", can the system be used to broadcast specific frequencies to directly effect animate/inanimate objects?

Im interested in connecting with people who have experience using resonance frequencies, know about sound.
