Abstract: A projection screen apparatus for reproducing the coherence between a visual image and associated acoustic signals. The projection screen apparatus includes a sound broadcasting device and screen that is transparent to sound waves disposed between the sound broadcasting device and the audience, whereby the projection of video and sound broadcasting are simultaneously implemented with respect to the audience. The screen includes multiple layers of white fabric that are superimposed and joined together such that the screen provides a surface that is both transparent to sound and sufficiently opaque to view a projected image.
