Certified acoustic performance: Ritmica D2, Ritmica Wood D2 and E.Box under test

Testing at Istituto Giordano Confirms the Soundproofing Performance of Etoile Partition Walls and Acoustic Booths for High-Efficiency Work Environments

Performative Architecture: The Measure of Design

Acoustic design in contemporary spaces has long moved beyond a purely technical dimension to become a foundational element of architectural projects. Sound is no longer a by-product of inhabiting a space, but a raw material that the designer must be able to orchestrate with the same precision devoted to light, volumes, and materials.

From this perspective, Etoile has developed the Ritmica D2 and Ritmica Wood D2 partition systems, along with the E.Box phone booth, subjecting them to rigorous acoustic certification tests at Istituto Giordano in Gatteo (RN), a European center of excellence for the performance analysis of building products.

Sound Control Technology

The acoustic tests were carried out in accordance with specific UNI EN ISO standards, using reinforced concrete reverberation chambers with 40 cm thick walls to ensure isolation from external interference. The experimental setup involved installing the partitions in a real-life configuration, creating two separate rooms. In one room, a controlled sound generator was placed; in the other, a detection instrument measured the intensity of the transmitted sound.

The acquired data, processed using certified software, yielded a precise decibel (dB) value quantifying the product’s sound insulation performance. This parameter is essential for environments such as executive offices, open-plan workspaces, and shared areas—where acoustics are no longer a secondary requirement but a fundamental element of environmental comfort.

From Separation to Connection: Understanding Sound as a Tangible Element in Spatial Design

With Ritmica D2, Ritmica Wood D2, and E.Box, Etoile continues its design research based on modularity, integration, and precision. The partition walls are not conceived as mere elements of separation but as active components of the space: they organize functions, channel light, and, as in this case, manage sound propagation.

The certifications obtained are not mere technical formalities or simple compliance stamps: they are tangible proof that even silence can be deliberately designed. In Etoile’s architectural language, every element—even the most subtle—actively contributes to shaping the space.
