One thing everyone has noticed with advances in technology is that everything is getting smaller. Computers that used to take up whole rooms can now fit into you pocket! If you’ve every been to a concert hall or even saw the inside of a recording studio you would notice sound diffusing material on the walls. This is called a Schroeder diffuser. Yun Jing, an assistant professor at North Caroline University has found a way to make a typical Schroeder diffuser 10 times thinner! It is amazing what technology has done and what new inventions pop up every day.
