Décasters

Décasters are a type of specialized sound-absorbing material designed to significantly reduce or eliminate acoustic reflections within a given space. Their primary function is to control reverberation and echo, creating a more neutral and accurate acoustic environment. This is achieved through a unique surface structure that deviates from conventional flat or uniformly porous absorbers.

The effectiveness of décasters stems from their complex geometric design. Instead of a simple porous surface, décasters often feature an arrangement of irregular shapes, cavities, or diffractive elements. These features are engineered to scatter sound waves in multiple directions and absorb their energy through internal friction within the material's structure. This scattering process breaks up the coherent reflection of sound, preventing it from returning to the listener in a predictable and potentially disruptive manner.

Décasters are particularly useful in acoustic critical applications where precise sound reproduction or speech intelligibility is paramount. Examples include professional recording studios, anechoic chambers, concert halls, and even specialized spaces like audiology booths or acoustic testing facilities. By minimizing unwanted reflections, décasters allow for a clearer perception of the intended sound source, whether it be music, speech, or a controlled acoustic signal. Their implementation contributes to a more controlled and less colored sound field.
