Noise from railway sidings in the new Environment Act

It is always difficult to explain that, under current legislation, the noise of a particular train in a timetable is covered by certain standards and calculation and measurement methods, but the noise of the same train outside the timetable is covered by industrial noise with ot

Artificial Intelligence and Machine Learning: the future of sound in pictures

There was no such thing as Artificial Intelligence 50 years ago. But senior advisors Bert Peeters and Erik van Gils have been getting to grips with it for several years now. With 19 years and 13 years with M+P respectively, they now have the necessary experience.

Measuring with Yasmin

No, Yasmin is not one of our M+P colleagues. It is the name of our measuring system. And an ingenious one to boot. Yasmin is able to work without anyone around, and can be monitored remotely.

Rapidly measure noise, roughness and track defects with ARRoW

ARRoW is short for “Acoustic Rail Recording on Wheels” and consists of a measurement system on the train and analysis software. The measurement system measures the noise and vibrations close to the wheels of the train, along with the position and speed.

A Testing Ground full of noise barriers and measuring equipment

Specially designed sound barriers that changed shape every 3 months, 13 measuring points behind and next to the barriers, and a mountain of measuring equipment. The Testing Ground for air quality was a major study commissioned by Rijkswaterstaat.

Measuring, modelling and experience

Noise and air quality are tested and assessed using calculation models. Why aren’t measurements used? How can measurements and models complement each other to form an assessment that best matches the perception and experience in the environment itself?

The hoarse roar of the sea lion male

Animals can cause noise pollution with their barking, roaring or screeching. On the other hand, some animals are bothered by ‘our’ noise. Nesting birds for example.

Measuring road noise on the go with CoMeT CPX

Do you want to know the noise reduction of a road? Do you want to check if a road constructor delivered a quiet road surface according to your specification? We have a measurement system that can answer these questions: CoMeT CPX.

Checking test track surface worldwide

Manufacturers from all over the world ask M+P to certify their test tracks: stretches of road surface to test whether new tyres or new vehicles are making too much noise.

Internship as a successful start

An internship at M+P can simply define your career. Senior consultant Ronald van Loon is still working with us almost 25 years later. And although Maarten Meeuwes has yet to complete his second M+P internship, he already knows that he'll be staying on afterwards.

Track vibrations are often only noticed when there's no noise

On the table is a coffee cup. The room is silent. And then, as if it is being awakened, the spoon in the cup begins to rattle. Briefly. The cause? A passing freight train. You can't hear this train thanks to a noise barrier. But you can feel it.

Increasingly quieter train tracks

In our densely populated country, people quickly get annoyed when a train flies past. Limiting such annoyance is crucial, especially if we want to make more intensive use of the environmentally friendly train tracks.
