There were days when there was no sound for people; I mean there was no artificial sound that comes from speakers or something. But, those days are gone and let them be gone and think about sound technology we have today. It is a rather developed technology and it is far and far away from that mono sound people used to have. There is no mono sound anymore and there is the stereo sound for people. Though, it is also more like archaism today because sound technology was greatly developed and today people have acoustic systems that make artificial sound sounds like real. Say, you buy acoustic system with all those speakers and sub-woofers and so on and so forth and all you have to do, is to place those in right order at home or car or whatever. And your sound will be something unbelievable and you will be stroked with it. It is like voices and sounds are all around you and it seems like you are not listening for that music but you are covered and surrounded with music. And if watching a movie it is like you are the part of that movie and there you are in that same forest or something.
