VIRG’ optima acoustic grilles

Industrial acoustic grille: customized silent ventilation

Ventilation systems are essential to the proper functioning of industrial and technical buildings. However, they are very often a weak point in terms of noise. Industrial acoustic grilles make it possible to reconcile air circulation and noise reduction, while meeting the regulatory and technical constraints of professional environments.

The VIRG’ optima acoustic grille, developed by ECIB, is part of this approach: offering a quiet, high-performance ventilation solution tailored to the requirements of each industrial project.

What is an industrial acoustic grille?

An industrial acoustic grille is a ventilation device specially designed to limit the propagation of noise through a building's air inlets and outlets. Unlike a conventional ventilation grille, it incorporates absorbent elements and an internal design that attenuates sound waves while maintaining controlled airflow.

This type of grid is particularly used when:

• technical equipment generates high noise levels,

• Ventilation is essential for the site to function properly.

• Acoustic requirements are strict (industrial environments, urban areas, sensitive sites).

What is the purpose of an acoustic ventilation grille?

Acoustic ventilation grilles play an essential role in industrial noise control. In particular, they enable:

• reduce noise pollution emitted to the outside,

• protect nearby work areas,

• comply with the noise limits imposed by regulations,

• prevent noise transmission between different areas of a building.

It is often installed on:

• facades of industrial buildings,

• technical rooms,

• air handling units,

• generators,

• ventilation or extraction systems.

How does an acoustic grille work?

The operation of an acoustic grille is based on a simple principle: absorbing noise without blocking airflow.

The VIRG’ optima acoustic grille is designed with:

• a sturdy metal structure,

• internal absorbent elements,

• optimized airflow.

Sound waves are partially absorbed by the integrated acoustic materials, while air flows through the grille along a path designed to limit pressure losses. This design provides effective sound attenuation while maintaining the ventilation performance required for the site.

Acoustic performance and technical data

The performance of an industrial acoustic grille is mainly assessed through its sound attenuation, expressed in decibels (dB), and its behavior according to different sound frequencies.

The VIRG’ optima acoustic grille is designed to meet the demands of industrial environments:

• significant reduction in noise transmitted by technical installations,

• adjustment to the required air flow rates,

• compatibility with mechanical and climatic requirements.

The exact performance depends on the chosen configuration (dimensions, thickness, materials), allowing for a customized approach tailored to each project.

Industrial applications of acoustic grilles

Industrial acoustic grilles are used in many different sectors:

• manufacturing industry,

• energy,

• logistics,

• data centers,

• technical service buildings,

• transport infrastructure.

In each of these contexts, the acoustic grille effectively treats air passage points, which are often responsible for significant sound leaks.
