Symbols and specifications

αs = absorption coefficient in sabine

Hz = frequenty band in Hertz

DI/P30-25 = insulation plate thickness 25 mm

DI/P30-50 = insulation plate thickness 50 mm

Attenuation example

example:
Duct of 0.50 x 0.40 m
Frequency: 2000 Hz
Reduction per channel:
type 602 25mm: 9 dB
These graphs are the translation of the formula:
∆N=1,05αs1,4 p/s dB/lm
with ΔN = noise reduction in dB /lm.
αs = sound absorption coefficient according sabine.
p = inner circumference of the channel in lm: 2 (a + b)
s = inner surface of the channel in m2: (a x b)
