Dramatically Reduce Rail Noise Without Spoiling the View

Dramatically Reduce Rail Noise Without Spoiling the View

Soundim manufactures award-winning low-height barriers that reduce railway noise without restricting passenger views.

Rail operators and network owners no longer need to use large, unsightly structures to protect nearby residents and businesses from railway noise.

This is because Soundim’s noise barriers have been designed to provide exceptional sound dampening without being obtrusive; blending into the landscape and ensuring train passengers retain a clear view.

Eliminating Noise at the Source

The majority of noise caused by trains travelling at under 200 kilometres an hour is created by the wheels and rails.

With this in mind, Soundim’s barriers work by blocking and absorbing the majority of noise at its source:

Jukka Näräkkä, Head of Business Development at Soundim, says:

“In other words, as close as possible to the point where a train’s wheels meet the rails.

“The resulting noise reduction is essentially the same as with higher barriers, but is more cost efficient and doesn’t block the view.”

Market-Leading Noise Reduction

Dependant on project factors such as train type, speed of travel and track conditions, Soundim’s barriers are capable of reducing noise levels by up to 12 dBA – and are particularly successful at reducing those high frequency sounds human ears like the least.

This is because they have exceptional absorption and insulation capacities – more so that typical hard structure solutions.

This is backed up by the following European standards that Soundim’s noise barriers have met.

  • Noise absorption 13 dBA (Class A4) – EN 1973 2 and EN 1793 3.
  • Noise insulation 30 dBA (Class B3) – EN 1973 2 and EN 1793 3.
  • Total noise reduction of up to 12 dBA – SFS-EN ISO 3095.

The company has also received an Innovation and Railway Research Award for passenger services from the international railway sector professional association UIC.

A Flexible, Modular Solution

Taking all this into consideration, it’s easy to see why Soundim is one of the top three providers when it comes to sound reduction solutions.

Tero Lepistö, Soundim CEO, enthuses:

“However, when it comes to a flexible, modular sound reduction solution, I’d say there’s no one better,” enthuses Tero Lepistö.”

This is because the barriers have a simple, modular design that can be installed directly into the track bed. Not only does this allow them to be uniform and independent from their surroundings, it also enables significant cost savings in terms of a solution’s design and construction.

Lepistö, says:

“With no exceptions, all our customers agree that the sound reduction is high and the product is easy to install. That’s what they really like about our product.”

Thanks to their modular design, Soundim’s noise barriers are also suitable for a vast range of rail projects.

Whether new or retrofit, they work across all track conditions and structures, and are suitable for use on:

  • Varying and difficult terrain
  • Curved tracks
  • Bridges
  • Any structures with special fixtures
  • All types of rail systems, including trams and subways.

It’s also possible to ‘personalise’ Soundim’s noise barriers, Lepistö adds.

Lepistö, points out:

“Customers can ‘decorate’ their fencing with their specific company colours or even wooden covers etc, providing yet another level of flexibility.”
