394 HlLLIARD October to have a committee of the Society of Motion Picture Engineers provide a recommended curve in the same manner that the 35-mm field has already been standardized. In closing it is recommended that the following steps be taken to standardize 16-mm sound-on-film reproduction. (1) Use a reproducing characteristic which is similar to the 35-mm characteristic except for minor deviations on the very low and highfrequency bands. (2) Provide recommended reproducer characteristics which will vary depending upon the type of loudspeaker used. (3) Publish information about currently available test films in order to accomplish this standardization.

(4) Establish a responsible group to correlate recording and reproducing activities so that standards may be modified when the art permits. This material has been presented in the hope that a discussion of the principles involved will enable workers in the field to arrive at an agreement which will promote higher standards of quality in the 16mm field.
