Noise monitoring system for railway project

As construction work on one of Banedanmark’s (Rail Net Denmark) new tunnels begin, the company monitored its noise levels closely to reduce the impact on local residents.

Due to open in Autumn 2018, the 60 km double-track electric railway, between Copenhagen and Ringsted, will be Denmark’s first railway for high-speed trains and enable passenger trains to achieve speeds of up to 250 km/h.

The city council sets noise limits, and Noise Sentinel, a noise monitoring solution provided by Brüel & Kjær, makes it easy for Banedanmark to monitor its levels, act accordingly and meet these standards.

Six noise monitoring terminals will be set up in key locations in the Copenhagen suburbs of Valby and Hvidovre, the two most populated areas along the new railway line – and the two areas most likely to suffer from noise pollution.

The New Line Copenhagen-Ringsted Construction Manager, Jette Aagaard said:

“The noise emanating from the construction site needs to be monitored continuously. That service is provided for us by Brüel & Kjær. We cannot remove the noise pollution completely, but we can certainly provide information and do our utmost to keep it within the set limitations.”

With the Noise Sentinel Stakeholder web accessible via “The New Line Copenhagen-Ringsted” website, Banedanmark can share the real-time measurement data with local residents and then post activities and noise reducing initiatives.
