We analyze the transmission of noise from the outside to the inside and vice versa, as well as the transmission of noise between areas of the same building. Inadequate acoustic insulation can lead to high sound levels in the interior or exterior space that reduces privacy, comfort level and ability to concentrate; they limit the intelligibility of speech and have harmful implications on health. Noise can travel through direct transmission paths such as ceilings, walls, windows, doors, … but it can also travel through flanks, ventilation ducts or others.

At Acousthink we define and execute the constructive solutions necessary to comply with local regulations and requirements of each project, delivering comprehensive documentation with calculations, constructive details and acoustic measurements.

Acoustic partitions and soundproofed wall lining

Acoustic partitions and acoustic wall lining are constructive systems designed to reduce the transmission of sound between adjacent spaces. These systems are particularly useful in residential, commercial and industrial buildings where noise needs to be controlled to ensure privacy and acoustic comfort.

Multiple layers of special gypsum panels, mineral wool, acoustic membranes, anti-vibration elements, … are usually used.

Details such as correct placement of material layers, sealing of joints and penetrations, and proper installation of fasteners must be considered.

Soundproofed ceilings

An acoustically insulating false ceiling is a structure suspended under the main ceiling of an interior space, either by means of elastic supports or with a structure supported directly on the interior extrados, usually made with multiple layers of special plasterboard, mineral wool and acoustic membranes . These false ceilings are designed to provide acoustic insulation by reducing the transmission of sound between spaces and should not be confused with sound-absorbing false ceilings that are intended to improve the sound quality within a room.

Soundproofed floors

When we talk about “inertia bases,” we generally refer to structures used in industrial machinery to provide stability and absorb vibrations, but it also applies to the isolation of spaces such as recording studios, auditoriums, …

When designing and constructing inertia bases for noise-sensitive equipment or those that generate high levels of vibration, it is possible to incorporate features that help reduce sound transmission. This can include the use of sound-damping materials in the construction of the base, such as composite materials that absorb vibrations and reduce sound propagation.

Acoustic doors and windows

Carpentry is a critical component when acoustically isolating a space. It is often the weak point if it has not been dimensioned or installed correctly.

At Acousthink, we specialize in supplying and installing acoustic doors and windows.

Silenciador acústic rectangular


Acoustic silencers are essential devices for controlling noise in air conditioning or ventilation installations, and appropriate design and selection are crucial to ensure a comfortable and quiet environment for users.

The two main types of silencers are rectangular or parallel cell and cylindrical with or without a central core. Both offer different advantages and features that can better suit different situations. Airflow capacity, pressure loss, space availability, and required attenuation level are key considerations that determine the type, size, and characteristics of the silencer to be used.

Furthermore, accessories such as diffusers, bird screens, and deflectors can further enhance the performance and effectiveness of the silencer in noise reduction and protection against other external elements that may affect its operation.
