The use of the power level indicator with readings in decibels was standardized. Musically trained observers were tested on their respective instruments, untrained observers by voice. Their achievement test was compared with their motor capacity and sensory capacity tests. Conclusions were drawn in regard to the effect of pitch level, intensity level, instruments, and training.
