Sound power level ratings are shown in decibels, referred to 10-12 watts calculated per AMCA Standard 301. Values shown are for inlet LwA sound power levels for 100%, 50% and 0% of peak pressure in Installation Type B: free inlet, ducted outlet. dBA sound pressure values are weighted with 11.5 dB attenuation for each octave band at 5 feet.
