Absorber 1: Peak absorption at 5187Hz. Damping=1.34 (high)
Absorber 2: Peak absorption at 5178Hz. Damping=1.34 (high)
Absorber 3: Peak absorption at 12333Hz. Damping=1.34 (high)
Absorber 4: Peak absorption at 12333Hz. Damping=1.34 (high)
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.
