Road Noise Calculation with D-noise

The New Standard: sonROAD18

sonROAD18

For the calculation of road traffic noise

Based on the latest Swiss noise model sonROAD18 and the sound propagation model ISO 9613-2, road noise calculations can be carried out as a function of traffic composition, indicated speed and pavement properties. In addition, the impact of noise abatement measures at the source, such as speed reductions or low-noise road surfaces, and measures along the propagation path can be simulated.

The sonROAD18 calculation model was developed on behalf of the Swiss Federal Office for the Environment (FOEN) by Empa’s Laboratory for Acoustics / Noise Control and was  implemented by n-Sphere in the D-noise solution.

The sonROAD18 emission model is based on the CNOSSOS formalism. It describes drive noise and rolling noise separately for different vehicle types and takes into account important factors such as speed, gradient and road surface. The model is formulated in one-third octave bands and takes into account vehicle type-dependent sound radiation characteristics.

D-noise

Your advantage: bundled expertise

Are you looking for a strong partner for road noise calculation in D-noise?
We have implemented the sonROAD18 calculation model in D-noise – and have proven noise experts in-house.

With our expertise, you can:

  • Set up your road noise project professionally – from data acquisition to the final calculation and evaluation

  • Use any traffic data – combine Swiss10+ traffic data in sections, optionally the SWISS10 converter for any count data (ADT, N1/N2, Swiss5) or specified emission levels with reference spectra
  • Perform detailed assessment of buildings, apartments and undeveloped parcels – with precise assignment of sensitivity levels and floor-by-floor usage

  • Plan and calculate forecasts and noise abatement measures – to ensure that your installation complies with the exposure limit values in accordance with the NAO

  • Create complex and reusable evaluation templates – for precise analyses and graphics
  • Have individual extensions developed for D-noise – from new functions in the add-in to modern web tools for comparisons, visualization and the rapid calculation of new noise scenarios
