ANSI S12.2-1995 (R1999)

Criteria for Evaluating Room Noise

Defines four sets of criteria for evaluating room noise: (1). Balanced noise-criterion (NCB) curves, (2). Room-criterion (RC) curves, (3). Criteria for acoustically-induced vibrations, and (4). One-third octave band hearing threshold curves. Guidance is given for determining whether a set of octave band sound pressure levels satisfies a specified NCB or RC curve. Guidance is given for using the NCB or RC curves to evaluate a set of octave band sound pressure levels as room noise. Guidance is given for using a set of octave band sound pressure levels to determine the likelihood of audible acoustically-induced vibrations. Guidance is given for using the one-third octave band hearing threshold curves to evaluate a low-noise situation.
