Acoustic Foam Pyramid

The acoustic panel pyramid is designed for correcting the acoustics of a room.

The main physical phenomena that the pyramid is designed for are reverberation and the frequency characteristics of the room.

The volume of the material directly affects the sound wave absorption coefficient, while its form factor affects refraction and diffusion.

The pyramid acts as an absorber of primary, secondary, tertiary… reflections in the room's frequency response.

This changes the amplitude of the reflected waves and reduces phase sums and differences due to inductance.

As a result, the sound in the room in its original form (sound from the acoustic system) reaches the listener without introducing any artefactual changes.

Also, based on the terminological definition of reverberation, the sound wave is constantly reflected with less intensity and thus fades much faster.

The sizes of the pyramid (30,50,90,120,150) represent the volume of the material and are proportional to its absorption.

We sell acoustic foam pyramids, as well as acoustic foam in other shapes.

We have the largest selection of acoustic foam panels!

Due to the high porosity of the material, it absorbs sound waves very well and converts them into very little heat.

As sound passes through numerous pores, it is diffused in the acoustic foam, thereby losing its pressure and transforming from sound energy into thermal energy.

Acoustic foam is often used to reduce echo by mounting it on the walls of large rooms.

The effectiveness of acoustic foam panels can be increased by providing an air gap between the acoustic foam board and the wall.
