If you watch the curves closely you will see that there is a frequency range between 135 and 700 Hz where the fluffy 5000 Pa*s/m² material absorbs better. Moreover, the 45000 Pa*s/m² material aborbs worse than the 16800 Pa*s/m² material. |
Very intersting topic!
Those simulation are a bit contradictory to the density tests Ethan made.
If 705 has about 45 kPA and 703 has about 17 kPa, the simulation indicates that 705 should work worse in the bass range but in the tests it never works worse. Not for 3" thickness and not for 6" thickness.
