This is a very logical question and and should be easy to answer.     I have high frequency hearing loss and have an old set of TRT devices and notice now with my hearing loss I can no longer hear the slight wispering sound that the TRT device produces.  My Zen hearing aids have a white noise and I can hear the noise that it produces and it only seems natural that if one cannot hear the noise produced by the original devices that I should use my Zens for my TRT program.  Really need some input on this situation. Jon
