content name:
  The potential for substantial noise reductions by measures related to tyres and road surfaces are explored. The variation in noise level within various tyre classes was studied in [Sandberg, 2006a]. The data compiled there seemed to be rather consistent, suggesting that if one includes several hundreds of tyres in the tests, the variation (range) will be 6-8 dB within a certain subcategory of car tyres and about 10 dB within the total car tyre category (category C1 in formal tyre terminology). Generally, tyres are not interchangeable between the subcategories, which means that the range a vehicle manufacturer or owner can “play with” is 6-8 dB. This report is part of the ongoing pilot study.

The similarity algorithm calculates how much two contents in the system are similar to one another. So far, similarity is calculated based on similarity of the project type, area of interest and user type. Generally, if two contents have more parameters in common they are more similar to each another. More information.
