Absorber 2: Peak absorption at 16617Hz. Damping=1.34 (high)
Absorber 4: Peak absorption at 5173Hz. Damping=1.34 (high)
WARNING: Layer of air in front of the absorber does not affect absorption.
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.
