Human Ultrasonic Hearing

Scientists since 1954 have known of the capability of humans to hear 
ultrasonic frequencies (23,000 - 100,000Hz.).  The only problems has 
been : 1)  Up-shifting audio sound cleanly to ultrasound (for speech 
comprensibility); and 2)delivering the ultrasound to the body.
I have spent the last 5 years developing a portable device which 
addresses and handles these problems.  The technology has been tested on 
severely and profoundly deaf adults and children (as well as normal 
hearing individuals) with excellent results.  Conversational speech as 
well as music is easily heard and understood.  This is a noninvasive 
approach and thus offers a viable alternative to the cochlea implant 
proceedure.
I thought it was time to let the news out.
