In all cases, the elbow has an overall detrimental effect on the noise levels, having an overall A-weighted decibel difference of up to 5 dB at peak efficiency for both 100% and 70% tip speeds.
The overall A-weighted decibel difference for the area ratios is less than 2 dB, such that the overall effect is negligible.
The overall A-weighted decibel difference for all orientations of the elbow is less than 3 dB, such that the overall effect is negligible.
25D for the 610-mm (24-in) diameter fan increased the overall A-weighted decibel level by as much as 6 dB and by as much as 8 dBA for the 914-mm (36-in) diameter fan.
The overall A-weighted decibel levels of the contractions for the 914-mm (36-in) diameter fan are less than 2 dB, such that the effect is negligible.
Each mode of traffic noise consisted of eight different noise events played back at five sound pressure levels ranging from 45 to 65 A-weighted decibels for a total of 40 noise events.
Cpk] (C-weighted peak sound pressure level) > 135 A-weighted decibels [dB(A)]}.
