This film shows Joseph T. Tykociner's sound on film apparatus and gives a description of its method of operation. Includes pictures of J. T. Tykociner, Jacob Kunz (developer of the photoelectric cell connected with the new process), #B. Paine reading aloud, and Manoah Leide Playing the violin. The film also shows pictures of the soundtrack and how it is affected by sound such as speech, the ringing of a bell, and the violin. This clip was produced from a videotape dub, of a duplicate a film was made in 1954 by the Motion Picture Society of America, in order to match the sounds of Mrs. Tykociner and the violinist. The original demonstration film was produced in 1921-22.

To see the mostly restored video for the sound on film demonstration (with the help of a generous grant from National Film Preservation Foundation (NFPF) to preserve the motion picture film elements and potentially restore the unknown sound elements from Tykociner's experiments), see: https://mediaspace.illinois.edu/media/Joseph+Tykociner%27s+Demonstration+of+Sound+on+Film+Technology...
This film represents the latest results of an ongoing research project to decode the original audio from Tykociner’s sound on film demonstration.
