20 years of supplying recycled tools for a quieter railway

It is now recognized that permanent exposure to noise and vibration management can be harmful. The most effective way to reduce railway noise and vibration emissions is to use the new highly absorbent acoustic mini-walls rated A3 or 11 dBA while currently optimizing the amount of recycled material by 70%.

The community expects good, innovative design in and around new and existing railway tracks, with significant noise reduction where the products should easily adapt to the existing track.

Particularly in a dense urban environment, the management of noise and vibration from railways above and below ground is becoming an increasing issue on major rail corridors in Australia. The community does not want large, unsightly concrete walls with high integrated energy to manage noise.

Through clever innovation, recycled products erected close to the noise source can reduce noise by up to 11 dBA, while providing passengers and the community with an unobstructed view. Rail vehicles generate rolling noises, airborne flange noises and vibrations during operation. This is due to the roughness and imbalances of the wheels and the undulations on the running surfaces of the rails.

Surface defects such as head cracks, ripples and slip waves on the rails are among the most common sources of vibrational interference and combine with high airborne noise generated by the wheel-rail interface.

The New 20th Anniversary Updated Noise Toolkit

STRAILastic’s “Noise Abatement Toolkit” for noise and vibration reduction for railways is significantly enhanced with all products offered with the new version 2.0 surface rated A3 or 8 to 11 DBA. This updated range offers cost effective, recycled and proven options to enable acoustical engineers and asset managers to better manage noise reduction for new and existing transportation systems.

Constructed from multiple layers and materials, it combines all the benefits of durable and stable rubber compound, now complemented by a highly absorbent surface. As before, these products require minimal planning approvals, have high impact, UV, graffiti and fire resistance, with minimal material fatigue caused by vibration or train pressure and suction forces.

Thanks to their good design, they blend into the environment without acoustic bridges, allow simple approvals and are easy to install. STRAILastic supplies mini piles/soil screws and sleeper extensions, or they can be bolted to existing walls and concrete foundations.

Mini noise walls have a very low visual impact which can be further enhanced by attaching local scenes screen printed on the obverse. Additionally, with no planning approval required, delays and costs are reduced, compared to the major planning challenge with large concrete panel walls.

New TP 2.0 acoustic panels for tunnels and walls

Airborne rail noise can propagate into the passenger train compartment inside the rolling stock, where strict limits are placed on rolling stock manufacturers to manage this noise. Strailastic TP acoustic panels are molded to the curve of the tunnel and designed to withstand the extreme push/pull forces generated by pressure and suction forces generated by trains traveling very close to the panels in tunnels.

The TP panel can be combined with an on-track absorption panel or Inox 2.0 rail web dampers to further reduce noise and vibration while providing a safe escape route. Purasys vibration attenuation systems complete the airborne noise toolbox to isolate and economically manage the impact of vibration through combinations of sub-ballast mats and special elastic support, as well as bearings for vibration systems. spring mass in the railway superstructure.

As always, STRAILastic will work with projects to modify our products to suit an individual project. We can close our eyes, but not our ears.
