Directly applicable solutions for quieter vehicles

Erik de Graaff: “Road traffic is one of the major causes of noise pollution. This is certainly no surprise: there are millions of motor vehicles on European roads at any given moment, and the fleet is increasing by the year. M+P has been representing the Netherlands on various technical assessment committees for 25 years. We take maximum advantage of our extensive experience with sound measurements and the acoustic behaviour of vehicles to assist with the development of quieter road vehicles.”

Limiting noise pollution for a healthier living environment

The noise produced by vehicles is bad for your health. This is why the reduction of road traffic noise deserves attention. Part of the solution lies in reducing the tyre noise on a road surface using “quiet asphalt” and quieter tyres. The other part is the vehicle itself.

There are many causes of noise pollution

There are many sources of noise pollution produced by vehicles, such as the engine itself, the exhaust and the drive mechanism. But process noises can be just as bad, such as loading and unloading and a cooling installation.

M+P has been providing advice about European approval regulations for 25 years

Standards for the maximum permissible noise emission of vehicles have been in place since 1970. This is regulated through a European harmonised type approval (70/157/ECC). M+P has been representing the Netherlands at various technical EU and UNECE committees for compiling inspection regulations for 20 years. We work closely with RDW, the Ministry of Infrastructure and the Environment, the EU and industry.

Immediately applicable solutions for quieter vehicles

The legislator is demanding quieter vehicles, but this requirement is also demanded by customers. M+P works and cooperates at all levels. For example, if a bus company wants to provide a better service to its passengers by improving the noise of the vehicle interior, the entire vehicle needs to be quieter. We will therefore undertake detailed acoustic research, source detection and design advice. It would be our pleasure to become your in-house consultant.
