"tFnsiie^cad Inlet and Cufiaf paver ratings are 3 d6 !o ••ver than total fan cower!evels under the asunrpian that"tral° of the sound po^. •er can be<br />
attributed to each opercng. Silenced pover ratings include this 3 d6 reduction aswe9 as the silencer a ttenuation_<br />
Estimated Sound Pressure Levels Expressed in dB (pressure levels refe re nce 2x101 aticrobar)<br />
Directivity[Reflection Factor (0) is 4, qua rter-Spherical radiation; Distance is 5 ft.: A-weighting is in use.<br />
The estimated sound pressure level outside the fan due to an open inlet OR outlet is 80.6 dBA at 5.0 feet. The<br />
estimated sound pressure level outside the fan When BOTH inlet and ou tl<br />
et are ducted is 69.1 dBA at 5.0 feet<br />
(Housing Radiated Noise).<br />
