Fan Chart – explanation and definitions Static pressure A-weighted total sound power level A-weighted total sound pressure level Remote attenuation Sound pressure level The total A-weighted sound power level, LwA emitted from the power roof ventilator to the surroundings can be read in the chart. The sound pressure level at different distances from the power roof ventilator can be determined by using the following formula: Distance L (m) Attenuation Sound level at different octave bands Correction Koct (dB) Octave band mid-frequency (Hz) Sound path The total A-weighted sound power level ,...
