Wavebreaker creates a better sound environment for people to a lower cost for the transport sector in comparison with equal measures. It is well-known that heavy foundations are needed for higher noise walls. This is a significant cost-driver in infrastructure projects.
Wavebreaker noise reduction through sound interference effect is equal to a virtual higher noise screen. By simulating the additonal extra height of the noise wall that is needed to be equal to using Wavebreaker, it is possible to compare costs for different alternatives.
Wavebreaker represents obvious customer value of both lower noise and lower costs.
lower costs,
same noise reduction.

Prolong the lifetime of an acoustically non-performing noise barrier.
Push your investment 10 to 20 years ahead in time. Reuse Wavebreaker on another location.
The following table shows examples of cost savings using Wavebreaker compared to building higher noise screens. The calculations are approximate and are based on the cost calculation model of the Swedish Transport Administration (Trafikverket).
The intended noise barrier is a wooden barrier built as a single wall without absorption (i.e. not a sandwich construction). The cost of a double-wall design with absorption is estimated in the model to cost about 2.5 more.
Additional screen barrier height | Cost savings with Wavebreaker, per 1000 m | Relative cost savings, per 1000 m |
From 2.0 m to 2.5 m | 90 000 € | 20% |
From 2.0 m to 3.0 m | 570 000 € | 60% |
From 2.0 m to 3.5 m | 1 100 000 € | 75% |
The examples of cost savings using Wavebreaker compared to building higher noise screens are based on the cost calculation model "Järnvägsbuse_2020 1.0" of the Swedish Transport Administration (Trafikverket). The costs are divided between materials and contracting costs with the cost base from 2017. These costs have been adjusted according to the following general indices normally used in Sweden. SCB-Producer Price Index (PPI), august 2017-August 2022 = +1.56. Investment index for railway, August 2017-August 2022 = +1.30. Currency exchange rate of 1 € = 11 SEK has been used.
