Part of a new metro line in Catanzaro travels on an elevated viaduct through a densely developed area. To help reduce noise without creating a visually imposing barrier, the project incorporated 15 millimeter transparent ACRYLITE® Soundstop XT panels that integrate with the structure while maintaining openness along the route.
When Noise Mitigation Becomes Part of the Design

Expanding Mobility Without Compromising Community Comfort
As cities grow, rail systems are increasingly relied upon to connect residential neighborhoods, employment centers, healthcare facilities, educational campuses, and commercial districts. These connections improve mobility and create new opportunities, but they also introduce a challenge that infrastructure designers know well: how to bring transit closer to communities without bringing unwanted noise.
The challenge becomes even greater along elevated rail corridors. Viaducts and guideways allow transit systems to move efficiently through complex urban environments, but they can also extend rail noise into surrounding areas. In densely populated settings, successful noise mitigation is not simply about meeting acoustic requirements. It is about helping new infrastructure become part of the community it serves.
When Noise Control Must Follow the Design
Along elevated rail corridors, noise barriers are more than acoustic solutions. They become part of the infrastructure itself, influencing how the structure looks, how passengers experience the journey, and how communities perceive the infrastructure around them.
In many cases, the barrier must follow the viaduct's geometry, align with curved structural elements, and maintain a consistent visual rhythm along the route. When architects and engineers envision a barrier that becomes part of the design, material capabilities suddenly become a critical factor.
Design Freedom Through Thermoformability
One of the defining advantages of ACRYLITE® Soundstop XT is its ability to be thermoformed into precise geometries.
This capability gives designers greater freedom to develop noise barrier systems that complement the infrastructure's architecture. Curved profiles, custom contours, and project-specific geometries can be achieved while preserving the optical and acoustic properties required for transportation applications.
Protecting Communities While Preserving Openness
Effective noise mitigation is ultimately about people.
Residents living near rail corridors want the benefits of improved transportation, but they also want to preserve the comfort and character of the places they call home.
Traditional opaque barriers can reduce sound, yet they often create a different challenge by introducing large visual walls into the environment. For communities, the perception of infrastructure can be influenced just as much by what they see as by what they hear.
Transparent barriers made with ACRYLITE® Soundstop XT help address both concerns simultaneously.
By reducing the visual presence often associated with conventional noise walls, they allow the infrastructure to blend more naturally into its surroundings while preserving sightlines and visual openness. Rather than separating the rail corridor from the community around it, they help maintain a stronger connection between the two.
The result is a solution that supports quality of life in multiple ways: by helping reduce noise exposure while avoiding the imposing appearance often associated with traditional barrier systems.

Preserving Views Through Transparent Noise Control
Transparency benefits more than just neighboring communities.
Passengers traveling on elevated routes often enjoy views of the surrounding landscape, whether that means urban skylines, neighborhoods, parks, waterfronts, or natural scenery. Long stretches of opaque barriers can diminish that experience and create a sense of visual confinement.
The high transparency of ACRYLITE® Soundstop allows natural light and views to remain part of the journey. This helps create a brighter, more open travel experience while reducing the enclosed feeling sometimes associated with continuous barrier systems.
Preserving the View for Years to Come
The openness and visibility that enhance the passenger experience are also among the defining visual characteristics of a transparent noise barrier. Preserving those qualities over time is an important consideration for infrastructure owners and designers alike.
ACRYLITE® Soundstop XT is engineered for long-term outdoor performance, helping barrier systems maintain their clarity and appearance despite continuous exposure to sunlight, weather, and fluctuating temperatures. As a result, transparent noise barriers can continue to support both the aesthetic vision of the project and the experience of the communities and passengers who interact with them every day.
Integrating Noise Control into Modern Infrastructure
The most successful infrastructure projects do more than move people efficiently. They fit naturally into the environments where people live, work, and travel.
By combining acoustic performance, transparency, long-term durability, and the ability to be thermoformed into complex geometries, ACRYLITE® Soundstop XT enables designers and engineers to create noise barriers that support the vision of the project rather than constrain it.
