Abstract

1,088,756. Acoustic lenses. DECCA Ltd. Jan. 28, 1966 [Feb. 1, 1965], No. 4280/65. Heading H4X. A sound distributing lens, particularly for use with a horn driven by a ribbon loud-speaker, comprises means such as plates 12, 13, defining two spaced aligned apertures between which are located zig-zag plates 18-27 which define a number of acoustic paths between the apertures, the acoustic delays of the successive paths increasing progressively from the centres of the apertures.
