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
I thought it was time to let the news out.
