Absorbent treatment for multipurpose room.

Industrial premises are often used to develop activities in which the acoustics of the enclosure play a very important role.  In this project, an acoustic treatment based on the introduction of absorbent materials on walls and ceiling has been applied, in order to control the general acoustics of the premises, which has the aim of controlling the reverberation time for different types of activities, enabling a suitable acoustics for each one.

Acustibaf-N40 type acoustic baffles installed on the ceiling have been used for this project.  Acustison-50A.type multi-hole modular absorbent panels have been installed on walls.

The form in which the reverberation time is adjusted in a multi-use room is based on achieving a reverberation time for the activities that require different types of reverberation because of their acoustic characteristics. The treatment is usually applied on the ceiling and walls, as these are useful surfaces for the absorbent treatment, without interfering in areas of the premises where the activities are going to be developed. The absorbent material must be applied as evenly as possible within the premises, ensuring that there are no facing areas without absorption. The particular shape, in this case, of the gable ceiling favours the sound diffusion as it prevents floor-ceiling parallelism, allowing a more balanced distribution of own modes, thus improving the premises’ frequency response.
