Estimated sound pressure based on free field hemispherical radiation (Q = 2), at the stated distance. Sound Pressure levels of a fan are affected by the acoustic properties of the surrounding's in which it is installed and consequently dBA levels cannot be guaranteed.
Refer to AMCA Publication 303 for furthur information. dBA levels are not licensed by AMCA International.
