The octave and A-weighted sound pressure levels are the levels expected to be obtained if measurements are performed in accordance with AHRI Standard 575-08, Method of Measuring Machinery Sound Within Equipment Rooms. Tolerances: The sound levels of identical unit selections can vary due to manufacturing tolerances and test repeatability. Variations of ±3 dBA on the A-weighted levels and ±5 dB on the octave band levels are possible.
