Abstract
Improvements have been made in the recording of sound on film, and in the reproduction of sound from film, that have resulted in an extension of both the frequency and the volume ranges. the low-frequency range has been extended by using a loud speaker unit that responds well at frequencies from go to 10,000 cycles per second. the high-frequency range has been extended by using a microphone of the ribbon type and by reducing the attenuation of the film. by using a narrower recording slit and a large mirror galvanometer the high-frequency response has been improved. the system for reducing ground noise has been simplified and made more effective.
