surface noise

Voorbeeldzinnen

1. Documentation of vehicle noise tests conducted on the surface
2. The surface of the test track shall be such as not to cause excessive tyre noise.
3. the surface of the track must be such as not to cause excessive tyre noise;
4. The limits for starting noise are defined at a distance of 7,5 m from the centreline of the track, 1,2 m above the upper surface of the rails.
5. The limits for stationary noise are defined at a distance of 7,5 m from the centreline of the track, 1,2 m above the upper surface of the rails.
6. Salt may alter the surface temporarily or even permanently in such a way as to increase noise and is therefore not recommended.
7. The limits for starting noise are defined at a distance of 7,5 m from the centreline of the track, 1,2 m above the upper surface of the rails.
8. The limits for stationary noise are defined at a distance of 7,5 m from the centreline of the track, 1,2 m above the upper surface of the rails.
9. The limits for the stationary noise are defined in a distance of 7,5 m from the centreline of track, 1,2 m and 3,5 m above the upper surface of the rails.
10. The limits for the starting noise are defined in a distance of 7,5 m from the centreline of track, 1,2 m and 3,5 m above the upper surface of the rails.
11. The greening of surface transport: Developing technologies and knowledge for reduced pollution (air including greenhouse gases, water and soil) and environmental impact on such areas as climate change, health, biodiversity and noise.
12. The limits for pass-by noise are defined at a distance of 7,5 m from the centreline of the reference track, 1,2 m above the upper surface of the rails for a vehicle speed of 80 km/h.
13. The limits for pass-by noise are defined at a distance of 25 m from the centreline of the reference track, 3,5 m above the upper surface of the rails for a vehicle speed indicated in Table 18 below.
14. In countries with winter climates, salt is sometimes used for de-icing. Salt may alter the surface temporarily or even permanently in such a way as to increase noise and is therefore not recommended.
15. In addition to the ongoing Commission initiative aiming at defining a road grading system, the Commission should, within 12 months of the entry into force of this Regulation, bring forward a proposal on the classification of EU roads according to noise generation that will complement noise mapping in motor vehicle transportation with a view to fixing appropriate priorities and road surface requirements and setting maximum road noise generation limits.
