we audiologists need to remember that the infra red systems are great for
mild losses or hi freqs but not for those over 50-60 dB. If any of you
have ever tried them, they work well for normals too. I've even turned
them up full volume where they begin to distort and I know they would not
work well for many. I always check them out just to keep my ears tuned in
to what is there and to let the theater know they are needed.
