Abstract: Despite a decade and a half of widespread use of multifre-quency test reels throughout the motion picture industry, the method of calibration has not been standardized. One result has been nonuniformity of calibration by various agents and another is lack of clear understanding of the significance of the calibration data. This paper discusses prevailing diversity of calibration results, describes a means of securing an absolute calibration of relative level at various frequencies, and proposes a standard definition of level of recorded signal and methods for measuring it.
