Abstract: This paper describes the high-frequency attenuation of sound waves passing through perforated motion-picture screens of the matte white variety. For the same percent of open area, a screen with smaller-diameter circular holes has fewer treble losses than one with larger-diameter holes. There is a limit to this effect, which occurs when the diameter of the hole is equal to or smaller than the thickness of the screen, at which point viscous losses occur in the cylindrical holes. The paper is not all-inclusive but should lead to further investigation on the part of screen and loudspeaker manufacturers.
