SOUND FILMS
NEW INVENTION METHOD OF REPRODUCTION MADRID. Dec. 4. In the .Rockefeller Building of the National Institute of Physics and Chemistry in Madrid two Spanish engineers, Scnorcs Selgas and Laffon, demonstrated yesterday a new system of reproducing sound photo-olcctri-cally. The new invention claims two important advantages over the systems at present in use for the manufacture of sound films; first, it makes easy and therefore less costly as well as more perfect the photographic development of the photo-sound ribbon, and, secondly, it registers sounds of higher frequencies. Theso results wero demonstrated before an audience comprising many men of science and- engineers, as well as the Minister of Education. Lengths of sound film made by the new process were thrown on the screen and finally a gramophone record of an orchestral performance was played and its photo-electric reproduction given immediately afterwards. This last demonstration enabled the audience to appreciate the perfection with which the reproduction amplified: the notes of the different instruments of the orchestra.
