Noise Criterion definition
Noise Criterion means the single number rating that is somewhat sensitive to the relative loudness and speech interference properties of a given noise spectrum. The method consists of a family of criterion curves extending from 63 to 8,000 Hz and a tangency rating procedure. The criterion curves define the limits of octave band spectra that must not be exceeded to meet occupant acceptance in certain spaces.
Noise Criterion means a single number for rating the sound quality of a room by comparing actual or calculated sound level spectra with a series of established octave band spectra.
