Absorber Parameters
• Absorber 1
Limp Membrane, 5 Kg/m2 25mm Porous Absorbent, 15000 Pa.s/m2 200mm Air Rigid backing • Absorber 2 Limp Membrane, 5 Kg/m2 200mm Air 25mm Porous Absorbent, 15000 Pa.s/m2 Rigid backing • Absorber 3 Rigid backing • Absorber 4 Rigid backing |
Absorber 1: Peak absorption at 53.3Hz. Damping=0.51 (low)
Absorber 2: Peak absorption at 54.8Hz. Damping=0.03 (very low)
Dotted lines indicate that the model used to estimate absorber properties has been used outside of its applicable range. Results may therefore be less accurate than where a solid line is displayed.
