Sherod, the utilization of this device requires rather elaborate services of an audiologist I seem to recall reading. Much back and forth interaction via computer programs with the firm in Australia. It's not a "one size fits all" device. Every patient has to have their software custom designed and tuned, just like hearing aids. The purveyors of that device aren't going to get any richer than your average audiologist probably. The scale of manufacturing is too small. Like every other service the medical industry provides, it's not for those cash impaired.
