Museum cooling system noise control
Acoustic management of technical equipment in sensitive environments is a major challenge. In sites open to the public, such as museums or heritage buildings, noise pollution can alter the visitor’s experience and have an impact on staff working conditions.

Introduction: controlling noise in sensitive environments
Noise abatement must meet a twofold imperative: guarantee effective noise reduction while preserving the aesthetic integration of the installations.
Against this backdrop, Groupe Boët, a specialist in industrial acoustic solutions and noise treatment, intervened at the Natural History Museum in Paris to treat noise emissions from a cooling system located in the immediate vicinity of frequented areas.
Context: a museum cooling system
The technical installation generated noise pollution incompatible with the acoustic comfort requirements of an emblematic cultural site.
The project had many constraints:
- direct proximity to visitors and staff
- high demands on noise reduction
- need to preserve the aesthetics of the site
- maintain continuous operation of equipment
In this type of environment, noise reduction solutions need to be unobtrusive, high-performance and perfectly integrated into the existing environment.
Industrial acoustic studies and noise analysis
Prior to any intervention, Groupe BOËT carried out comprehensive industrial acoustic studies to precisely characterize :
- noise levels emitted by the system
- noise propagation paths (airborne and structural)
- critical exposure zones
This site noise diagnosis enabled us to define an appropriate acoustic treatment strategy, combining several noise treatment devices for overall effectiveness.
This approach is in line with the need to control noise and noise pollution, which is essential in sensitive environments.
Industrial acoustic solutions deployed
Acoustic screen made of absorbent panels
A perimeter sound barrier was designed and installed around the cooling system.
It is composed of high-performance acoustic panels incorporating sound-absorbing materials, such as absorbent panels with a high sound-attenuating capacity.
This acoustic equipment enables :
- a significant reduction in airborne noise
- limiting the lateral spread of nuisances
- improved acoustic comfort in adjacent areas
These acoustic panels are part of the acoustic technologies for industrial and tertiary sites, providing long-lasting acoustic protection.
Acoustic enclosures with technical covers
In addition, an acoustic cover was installed over the equipment.
This acoustic cladding device acts as a partial acoustic enclosure to treat vertical emissions. It contributes to noise attenuation by limiting sound dispersion in the environment.
This type of soundproofing hood is particularly effective for technical equipment such as :
- cooling systems
- refrigeration units
- compressors or industrial motors (via additional compressor or motor silencers if required)
Acoustic enclosures are a key element of the overall noise reduction system.
Maintainability and architectural integration
From the outset, our solutions have been designed with operating constraints in mind:
- access maintained for maintenance operations
- demountable and modular structures
- unobtrusive visual integration respecting the heritage environment
This approach guarantees continuity of operation while ensuring effective noise reduction.
Results: noise reduction and optimized acoustic comfort
Groupe BOËT’s intervention achieved acoustic performance in line with the site’s expectations.
Observed benefits:
- measurable reduction in peripheral noise levels
- compliance with regulatory acoustic thresholds
- significantly improved comfort for visitors and staff alike
- maintaining cooling system performance
- aesthetic enhancement of the installation
The combination of acoustic panels, sound-absorbing materials and acoustic enclosures has resulted in comprehensive, sustainable acoustic management.
