AB - Measuring procedures and specifications currently used in the sound recording industry are inadequate. A weighting network should be used to objective noise measurement work to evaluate developments toward a lower noise system. We know that the ear is most sensitive in the 1 to 6 kc region, and it is possible to use preemphasis in this region. Better signal-to-noise ratio may be obtained in 15 ips magnetic recorders by utilizing fully their present capabilities. Subjective listening tests show that a system with the 1 to 6 kc region pre-emphasized (the AME curve) is some 7 db quieter than the same system using the NAB curve, but does not show any audible increase in distortion.
