Absorption dampens modes and enhances any additional room remedies

Evidence

Are resonant modes eliminated by adding absorption? No, but they are acoustically damped to reduce the height of the peaks and the depth of the dips, reducing “booms” and seat-to-seat differences. … In general, though, low-frequency absorption is desirable, as it will benefit any additional remedies that may be selected. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1569
