I am very much into video games. Day Z, Battlefield and stuff like that. In these games it is important to have good headphones so you can hear people sneak up on you, but recently, I have seen ads for 7.1 Surround Sound headphones that actually have multiple drivers in them so that the sound emits from multiple directions. I was immediately sold but in doing more research about the topic, I am now on the fence as to rather I think humans can actually pinpoint sound emitters based on ears alone, or if the brain creates our scene of where sound came from based on many factors that surround sound headphones would not aid any more than stereo headphones. On one hand, I hear that the shape of the ear, distorts sound that comes from the front and sound that comes from the back to help you ID the direction of the emitter but on the other hand, I hear that your brain uses your eyes and head motion in combination with your stereo hearing to compute where the sound came from. This morning, I was over the fence and was ready to buy a pair, but at lunch a few of my coworkers and I performed the experiment where one person closes his/her eyes and another snaps his / her fingers in-front or behind their face, turns out that no on at lunch would get the source 5 out of 5 times correct. When they snapped their fingers behind my head, I thought I even felt the wind on my face from the finger snap and yelled "FRONT!" just to hear people snicker and later find out that it was behind my head. Now I am back on the fence and I have a hard time not jumping down on the side that 7.1 headphones are BS. Can ears without head motion and without visual feedback get more than left and right volumes and distance? Can we tell if a sound comes from the front or the back? Thank you for taking the time to read this and looking forward to your answer. Kevin.
