[Elecraft] Left ear / right ear or stereo

[Andy Durbin]

It seems to be common to refer to using one ear for main RX and the other ear for Sub RX as "Stereo".   I have experimented with listening to more than one radio using stereo headphones and found the experience far from satisfactory.   My application was listening to Air Traffic Control and parachute demo ground coordinator with different ears.

Some time ago NASA did some research on presenting multiple radios in a true stereo "sound stage".  With suitable processing each receiver could be placed anywhere in that sound stage, not just in the left ear or in the right ear.  The sound stage could also be used to place passengers in the appropriate place when they spoke on intercom.

I learned about this  project during a visit to Langley but have not heard if there was any commercial development of the idea.  Anyone know if there has been any commercial application either for aircraft radios or for amateur radio?
