However, the noise generated at the inlet of the silencer Lw i is higher than the noise generated at the outlet of the silencer Lw o . It is therefore crucial to use the correct value depend on the placement of the silencer in the duct sys- tem, cf. drawing. When calculating the silencer for: • supply and outlet - use outlet noise Lw o • inlet and exhaust - use inlet noise Lw i Sound power level, inlet: Lw i Sound power level, outlet: Lw o 5 60 6 50 m mm 00 mm 20 mm 0 mm 0 m s=80 s=1 s=1 s=14 60 s=6 50 mm mm s=60 s=80 dB(A) dB(A) s=100 s= mm 120 s=140 mm mm 40 40 7 30 30 8 20 10 20 A [m²] 0,5 0,6 0,7 0,8 0,9 1,0 2,0 3,0 4,0 5,0 Kor. -3 -2 -2 -1 0 2 3 5 6 7 10 A [m²] 0,5 0,6 0,7 0,8 0,9 1,0 2,0 3,0 4,0 5,0 Kor. -3 -2 -2 -1 0 2 3 5 6 7 9 0 0 1 2 3 4 5 6 7 89 0 0 12 3 4 5 6 7 8 9 v (m/s) v (m/s) 10 11 12 13 14 15 16 17 18 58 Vyhradzujeme si právo vykonať zmeny bez predchádzajúceho upozornenia
