Quilted Fiberglass Sound AbsorptionThe Insulation Guy
"BSC" composite features a non-reinforced loaded vinyl noise barrier septum (right) with a quilted fiberglass sound absorber on both sides. Ideally suited as an acoustical liner the inner layer of quilted fiberglass decouples the barrier from the surface to improve its noise blocking ability while the outer layer adds sound absorption to the treated environment.

Room Sound AbsorptionSound Absorption Coefficient
The sound absorption coefficient is the ratio of absorbed sound intensity in an actual material to the incident sound intensity and can be expressed as. α = I a / I i (1). where . α = sound absorption coefficient. I a = sound intensity absorbed (W/m 2). I i = incident sound intensity (W/m 2). Absorption coefficientαfor some common materials can be found in the table below

Sound Absorption Coefficientan overview ScienceDirect
The sound absorption coefficient for metal foams at different frequencies increase with their thickness 25 . With thickening of the porous body the pore channels are extended and then cause more energy loss. It is also found that the peak of sound absorption coefficient will move to the low-frequency range for thicker porous bodies.

The Differences Between Conventional and Acoustical Foam
Aug 24 2012 · Acoustical foam is formulated to a firmness that offers the best absorption across all frequencies as a higher ILD (firmer foam) absorbs more low-frequency sound and a lower ILD (softer foam) absorbs more high-frequency sound. In a product like The Foam Factory s 3" pyramid tiles a balance between the two must be met to span the widest

Soundproofing vs Sound Absorbingthe differenceASI
Soundproofing vs sound-absorbing. There are two sides of the acoustical coin if you will. There are products that absorb echo within a room and there are products that will block or stop/reduce sound transmission. (There are some panels that will do a bit of both. These are generally called composites but for now let s keep it simple.)
