Sound Data BS848 Part 2 1985:Single figures on performance curves are overall inlet sound power levels, derived from measurements taken in Woods laboratoryspecifically under ducted conditions. For sound power levels in eight octave bands, apply the following corrections to the overall level.Useupper corrections when operating point is above shaded area, or lower corrections when operating point is below shaded area.
