Acoustic Walls

An acoustic wall is an acoustic structure used to shield noise from machinery, installations, or production processes. By partially or completely screening the noise source, the propagation of noise into the surrounding environment is significantly reduced.

At ALARA, sound-insulating walls are fully custom-designed. Depending on the application, the walls can consist of sound-insulating panels, sound-absorbing materials, and integrated features such as doors, windows, or ventilation openings. This creates a solution that not only reduces noise but also remains safe and practical to use.

An acoustic wall is particularly suitable when completely enclosing an installation is undesirable or impossible. Examples include large production lines, installations that need to remain continuously accessible, or situations in which multiple machines collectively produce noise. In these situations, a wall creates an effective barrier between the noise source and the surrounding environment without completely enclosing the installation.

Many projects use a combination of acoustic walls, silencers, and acoustic enclosures. ALARA assesses each situation to determine which solution or combination of solutions best meets the technical requirements and required noise reduction.

Acoustic walls are used in a wide range of industrial and technical environments where noise needs to be reduced. Common applications include:

• Production lines
• Generator installations
• Compressors
• Pump rooms
• Ventilation installations
• Technical rooms
• Power plants
• Waste processing facilities
• Water treatment facilities
• Logistics installations

Because every environment has unique requirements regarding safety, accessibility, and maintenance, each wall is fully tailored to the specific situation.

The level of noise reduction depends on various factors, such as the height and length of the wall, the position of the noise source, the distance to the receiver, and the characteristics of the noise produced.

During the design process, ALARA performs acoustic calculations to determine the performance required to meet the project objectives and applicable noise regulations. By using the right combination of sound insulation and sound absorption, noise levels can be significantly reduced.

Yes. One of the key advantages of ALARA’s systems is their modular design. This allows walls to be easily adapted when:

• Production lines are expanded
• Machines are replaced
• Installations are relocated
• Maintenance areas change
• Future expansions are implemented

This flexibility ensures that the investment continues to provide value over the long term.

Yes. An acoustic wall must not only reduce noise but also remain practical to use.

Depending on the application, the following can be integrated:

• Personnel doors
• Double service doors
• Sliding doors
• Inspection windows
• Transparent acoustic screens
• Cable penetrations
• Pipe penetrations
• Transport openings

All integrated components are designed to preserve the acoustic performance as much as possible.

Many technical installations generate heat and require sufficient air circulation. Ventilation is therefore considered from the initial design phase. ALARA uses solutions including:

• Acoustic ventilation grilles
• Acoustic air ducts
• Ventilation sets
• Silencers
• Natural or mechanical ventilation

This keeps the installation operating optimally without compromising sound insulation.

Yes. Acoustic walls are often used in environments where high demands are placed on durability and reliability. Depending on the application, the design can account for:

• Humid conditions
• Dust exposure
• Chemical exposure
• High temperatures
• Vibration
• Intensive daily use

Selecting the appropriate materials ensures that the systems continue to perform reliably over the long term, even under demanding industrial conditions.

Yes. Every industrial environment is different. ALARA therefore develops exclusively custom solutions. The design takes into account factors including:

• Available space
• Installation height
• Maintenance access
• Airflows
• Structural loads
• Safety requirements
• Required noise reduction
• Future expansions

This results in a solution that integrates optimally with both the installation and the client’s operations..

A project begins with an assessment of the noise source, surroundings, and technical parameters.

The project then typically follows these steps:

1. Assessment of the existing situation.
2. Acoustic analysis.
3. Engineering and 3D design.
4. Manufacturing of the wall panels.
5. Transport to the project location.
6. On-site installation.
7. Inspection and handover.

Because engineering, manufacturing, and installation are closely coordinated, installation can be completed efficiently while minimizing the impact on operations.

Yes. In practice, sound-insulating walls are often combined with other techniques to achieve optimal results. Common combinations include:

• Sound-insulating enclosures
• Acoustic ventilation sets
• Acoustic grilles
• Exhaust silencers
• Vibration isolation
• Acoustic doors

By designing these solutions as an integrated system, ALARA creates a total concept in which noise, ventilation, safety, and maintenance are perfectly coordinated.

A sound-insulating wall is only truly effective when it is fully tailored to the technical situation. ALARA therefore does not rely on standard panels but develops custom solutions based on the installation, environment, and required performance.

By combining expertise in acoustics, mechanical engineering, and project management, ALARA creates solutions that contribute to a quieter, safer, and more efficient working environment.

Clients benefit from:

• Custom engineering
• High acoustic performance
• Durable materials
• Easy maintenance access
• Modular expansion options
• Complete turnkey project management
