Innovative acoustic interference damper for traffic noise

WAVEBREAKER AB > PRODUCTS > CUSTOMER VALUE 

CUSTOMER VALUE

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.

COST COMPARISON

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.

SOURCES AND ASSUMPTIONS

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.

Wavebreaker AB disclaim all responsibility for the accuracy of the above numbers. The calculation examples are approximate and should be interpreted as guidance. Actual costs may vary depending on the circumstances of the actual location and in which country cost calculations are made.
