Traffic noise – consultancy services and accredited measurements

Noise from traffic is an increasing societal problem as the traffic network expands. Get advice on alleviating and dealing with traffic noise from roads, planes, railways, ships, and ports.

Accredited to measure and calculate all types of traffic noise

We know how traffic noise affects people, and we are accredited to perform measurements and calculations of all types of traffic noise. This means you will always receive qualified advice on how to reduce noise annoyances.

Noise mappings for environmental assessments / EIAs are among our specialised services in the area of traffic noise.

You will also benefit from our many years of experience and expertise in measuring, calculating, and advising in the areas of acoustics, sound and vibrations.

Which services are available within traffic noise?

Road noise - consultancy, measurement, and calculation
- Road noise consultancy services for new and existing roads, as well as for new construction projects adjacent to roads
- The Nord2000 model is used for road noise calculations, in accordance with instructions from the Danish Environmental Protection Agency. We produce a 3D noise model of the road and its surroundings, and show the noise distribution on a noise map.
- Advice on noise dampening measures, like the placement of noise barriers and earthworks, or acoustic isolation windows and soundproof façades for buildings. We can also help you determine the effect of noise reduction measures, such as:
  - Asphalt coatings and road surfaces
  - Noise baffles and barriers
  - Traffic and speed management
- Documentation of noise-related effects, such as noise maps and reports. To help you communicate the results, or as a supplementary decision-making tool, we can auralise the road noise via audio files that accurately reproduce how the road noise will sound in the future.
Traffic noise from railways, light rail, and metro systems
- Advice, measurements, and calculations of traffic noise from rail traffic. Rail traffic noise calculations and measurements are especially relevant to:
- Infrastructure projects in which noise must be reduced to the greatest extent possible
- Documentation of building plot noise along railways
- Other noise-sensitive applications along railways.
- Advice on the placement of noise barriers and baffles, as well as on the effects of other noise reduction measures, such as rail grinding. We can calculate the effects of noise before you build, such as for environmental assessments / EIAs.
Many years of experience in measuring and calculating railway noise. Among other projects, we prepared many of the reports that form the basis of the Danish Environmental Protection Agency's Nord2000 calculation method. We have also measured noise from the majority of train types that are on today's railways.
Traffic noise from aeroplanes
- Consultancy services for aeroplane noise from airports, airfields, and helipads, whether you need to prepare environmental assessments / EIAs or simply wish to gain insight into the noise impact from flight activities.
- Noise monitoring and measurements for individual planes, e.g. for approval of specific plane types.
- Noise mapping
- Consultancy on environmental adaptation, noise reduction and airport noise management
- Measurements for plane type approvals
- Consultancy employing DANSIM (Danish Airport Simulation Model), a calculation system developed in-house. DANSIM calculates the noise impact from airports based on actual or expected traffic, the flight path system, and the airport's surrounding topography.
- In-depth knowledge of airport and airfield traffic flows, making it possible for us to perform reliable noise calculations. You benefit from our expertise with the various plane types, their characteristics and their modes of operation, so we can make highly accurate noise impact determinations.
Traffic noise from ships, fast ferries, and in port areas
- Help handling and mapping out traffic noise from ships and fast ferries, and its effects on port areas.
- Know-how on the special noise rules that apply to fast ferries due to the high volumes of low-frequency noise that they often produce. Much of the associated sound propagation occurs over water, which generally does not dampen noise in the way that land would, and mitigating it requires particular expertise and knowledge of relevant standards.
- Noise calculations for the expansion of existing ports and the construction of new ports. We prepare a 3D model of the port and its surroundings, adjusted to reflect the planned changes. The noise calculation model is an excellent planning tool when designing new port areas or modifying existing ones.
