Busting the Myth – Pyramid Vs Wedge-Shaped Acoustic Foam

While soundproofing a homegrown or business assembling, it’s a given that you believe the most ideal arrangement should meet your acoustic prerequisites. Acoustic froth is a well known decision, and there are numerous contemplations that should be made while settling on the most appropriate item. Notwithstanding, a constant legend infests that there is an essential distinction in execution among pyramid and wedge profiles.


Pyramid and wedge-formed acoustic froths are both sound assimilation based arrangements, and both utilize open-cell innovation; there is no distinction in execution with regards to soundproofing.

The science

Acoustic froth works on the guideline of constriction, or the steady misfortune in power of energy when it goes through a medium. To get truly specialized, it expands the encompassing air opposition, which thus lessens the plentifulness of occurrence sound waves and converts the sound energy into a limited quantity of hotness.

In layman’s terms, that implies ingestion. Light is constricted by shades, X-beams are lessened by lead, and sound is weakened by froth.

The other kind of soundproofing arrangement is acoustic dissemination, where energy is scattered yet not consumed. Pyramid and wedge-formed acoustic froth are not dissemination based arrangements; they are just and consistently ingestion based arrangements. Whether a froth is pyramid or wedge-formed has next to no effect, as the actual cycle happens on the size of individual froth cells, not that of the froth’s profile.

Where did the fantasy come from?

The legend probably begins from contemplations Melamine Foam significantly less grounded in the realm of physical science or soundproofing execution.

To separate between themselves, makers produce different-formed froths to catch everyone’s eye. You can shape, contort, cut and shading acoustic froth some way you need, and by guaranteeing that pyramid and wedge-formed profiles produce various outcomes, you can advertise an item as being predominant in its treatment of acoustic waves.

While the facts confirm that decision of material, froth thickness, cell size and porosity are significant contemplations relying upon the recurrence of sound you need to treat, whether you pick a pyramid or wedge profile doesn’t have an effect. Actually acoustic froths in pyramid and wedge-formed arrangements act in the very same manner no matter what their profile or shading.
