[A REVISAR] Sound absorption or sound insulation?

When we talk about acoustic comfort, we need to take two different concepts into account: sound absorption and sound insulation.

These two properties are often confused when carrying out building work. The porous materials placed in the cavities of walls and envelopes (partitions, façades, insulating panels, acoustic screens) provide good sound absorption, but on their own they contribute very little sound insulation.

Sound insulation

Sound insulation is the ability of a material to create a barrier against noise, preventing it from passing to the outside or the inside and ensuring the comfort of the room, hall or home. This property is normally determined by mass: the higher the density of the material, the greater its insulating capacity.

Sound absorption

Sound absorption is the ability of a material to reduce the reflection of sound when a given amount of sound energy strikes it. Reverberation times decrease, which improves speech intelligibility in the room. These are normally highly porous, low-density materials.

In interior design with technical ceilings, sound absorption is usually considered the priority, whereas insulation is addressed at a structural level through the materials used in partitions and slabs.

In our general catalogue of technical ceilings, you will find a wide range of ceilings designed to improve sound absorption according to the requirements of each project: from mineral fibre ceilings with high acoustic coefficients to metal ceilings with medium absorption, combined only with thin acoustic fleeces.
