Information display devices such as flat panel TVs have become thinner and more beautiful due to the
development of IT technology. The thinner the thickness, the better the durability, the image quality beyond
the Full HD UHD, furthermore, it is possible to create a human-like appearance of the image. However,
design and image-quality developments have lowered the role of the speaker that plays the video, hiding it
as an invisible part, and preventing it from reproducing the direct sound. TV manufacturers are changing
the way to reproduce sound in a detachable design, gradually putting the speakers at the rear, or putting a
speaker on the outside of the TV side, which is disadvantageous for playing good sound. In this paper, we
propose a method to match the location of the sound and the sound position on the screen by utilizing the
advantage of the design of the TV. Using this method, we confirmed by analyzing the brain waves that the sound and the position of the screen are matched so that the viewer watches and the stress is reduced.
