This standard sets out two methods for determining a unique number called the noise rating (NR) number from the measured set of nine octave band sound pressure levels (31.5 Hz to 8 kHz centre frequencies in accordance with AS Z41) pertaining to the noise in a given environment. A numerical method and a graphical method for determining the NR number are described.
