12:00 p.m. Edgar Choueiri, a professor of mechanical and
aerospace engineering at Princeton University, has developed a
way to play true three-dimensional sound recordings over regular
loudspeakers, such as those found in televisions and computer
laptops. The technique may be used one day to allow 3-D
televisions to produce lifelike sound and to help people with
certain types of hearing impairments locate noises. This video
excerpt produced by the School of Engineering and Applied
Science includes segments demonstrating how Choueiri’s 3-D
filter works. To learn more about Choueiri’s research and the
3-D filter, watch the full-length video. Play the video

designed to work with loudspeakers -- not headphon
