Wish there was a way to analyze and quantify "MUCH less fatiguing".
There are aspects of hearing that are poorly understood. For instance there is emerging cellphone research that indicates that listening to speech in one ear is much more attention consuming than listening to the same conversation in an open room. It might be something of our nature that our brain expects to hear high sound components in a particular phase relationship that decodes into source and position and if the phase and "spatial" relationship is not present in high frequency audio it occupies the brain's "attention" and "energy" trying to decode it, much like the eye strain that comes from being unable to focus on an image. I know I find it very hard to listen to CW for any period of time that is only in one ear. What other kinds of reactions to audio are there that are not common knowledge? 73, Guy.
