Noise Reduction for New Transformer Station in Sydhavn
When new transformer stations are built, it should be ensured that noise from the transformers does not disturb neighbours in a densely built-up area. To meet the noise requirement of 40 dB(A) at the façade of the new transformer station in Sydhavn, Aarsleff Rails contacted IAC Acoustics to find a solution that could reduce noise from the transformers and also contribute to the ventilation system. The solution was IAC Acoustics’ Louvers, also known as acoustic louvers, which act as sound barriers while allowing airflow..
In 2021, Aarsleff Rails constructed a new transformer station in Sydhavn. The station consists of three chambers housing transformers, which supply power to the overhead contact line system. This process can be noisy, as the selected transformers generate approximately 51 dB(A). Since the applicable noise requirement at the façade is 40 dB(A), a solution was needed to effectively reduce the noise emitted by the transformers.
Noise barriers with natural ventilation
The project, managed by Aarsleff Rails, had to meet several important requirements, including noise reduction for nearby residents, cooling, and energy efficiency.
Calculations carried out in cooperation with the project engineers showed that IAC Acoustics’ Louvers could meet the demanding sound insulation requirements while also contributing to natural ventilation.
The final choice was the Noishield™ Model 2R acoustic louver, which offers unique properties, like it attenuates noise, allows airflow, and is virtually maintenance-free.

Manufacturing, delivery and installation of Noise Barriers
IAC Acoustics, a leading global manufacturer of robust, high-performance acoustic louvers with thousands of installations worldwide, was responsible for manufacturing, delivering, and installing the chosen solution. This was done in close collaboration with the consulting engineers and project managers from Aarsleff Rails.
The project was completed in December 2021.
