Abstract: Reproduction of speech and music with motion pictures is intended to augment enjoyment derived by theater audiences. Of the factors which contribute to ease and pleasure of listening to reproduced sound, the quantity (loudness) of sound available to listeners ranks in importance with the quality of reproduction. Quality is of little avail when satisfactory loudness does not accompany it, and increase of loudness cannot compensate for quality that is poor. Sensation level influences intelligibility and naturalness of speech and music and, therefore, must be considered an important element in the promotion of satisfaction with sound picture presentation in theaters.
