The left ear for me (since I'm in South Eastern Virginia) encompasses the Atlantic Ocean and the Western side of Europe. As with the right ear, the sound texture, position coming into the ear and where it ends up tells me where the location is. I'm stating fact when I say I'm usually within 1500 miles of the exact location and could be due to where the actual vibration surfaces first. I seem to pick up on a higher electromagnetic sound than most. If in doubt, I visuallize a map and a higher guided force will pin poin the location for me. This takes time and as you all know, that is a luxury most of us don't have right now. When things ease up, I'll be more than happy to explain and teach anyone how to do this. It deals with pressure and enegy.
