Noise Cancelling Heaphones Experiment

Testing out the theory of opposite soundwaves EDIT: A number of people have commented that this is "fake" and that no sound is being played 1:00 in. It's true that no sound is coming out of your speakers, but it's not "fake." Allow me to explain... The audio files that play at 0:43 and 0:50 are exact opposites of each other. Those same audio files were both attached to the video project at the 1:00 mark in the video editing software that I used. Because they both started at the exact same moment, the computer analyzed the two audio files and determined that combined, they should produce no sound. Therefore, when I exported the video project as a movie file, it had the same effect as if I hadn't attached either audio file in the first place. I hope this clears up the inadequate explanation I provided in the video itself.
