I don't know who it was that needed to communicate with people in MRI
imagers, but I would imagine that a system like that in airplanes would be
good enough. You know, those earphones that work by pulsing the air instead of
pulsing a membrane which would then pulse the air. All you would need is a
long tube to carry the air (I guess, as I don't really know). Hope this might
help. Ron 'Vulture' Helwig
