Alan Blumlein (one of EMI’s original engineers), created this historic video demonstration of his creation of stereo sound. In this video, they do various sound tests in order to test the sound quality, the loudness, and other things. He uses a team of people as test subjects so that he could test and analyze the data at a later time. An incredible piece of archive footage well worth a watch.
