Definition of Room Criteria (RC)

Room Criteria (RC) is a standardized method for evaluating background noise in occupied spaces. It measures sound pressure levels across the frequency range from 16 Hz to 4000 Hz, with emphasis on the mid-frequency average and the perceived balance between high and low-frequency components. RC values are represented as curves on a chart, with each curve corresponding to a specific sound level spectrum.
