General information and noise measurements

A number of paddock rules apply at CM.com Circuit Zandvoort, in order to guarantee safety for all those present. In addition, the circuit is bound by noise rules. More information about this can be found on this page.

Paddock Regulations

A number of paddock rules apply at CM.com Circuit Zandvoort, in order to guarantee safety for all those present. A number of these rules have also been introduced to apply the national environmental rules on CM.com Circuit Zandvoort as well. Therefore, a better environment starts with the teams on the track.

Rules are described in the special paddock regulations that relate to gas cylinders and their protection. The conditions that fuel storage locations must meet and the resulting tank regulations are also mentioned. In addition, the paddock regulations pay attention to the disposal of wastewater and collection points for oil residues.

Finally, the regulations refer to the placement of tents and the parking of vehicles, as well as maximum speeds in the paddock and the use of pit boxes.
Consult the paddock regulations of CM.com Circuit Zandvoort and/or the paddock application user license document of the municipality Zandvoort for more information.

Noise measurements

CM.com Circuit Zandvoort is bound by some noise rules. These rules apply to all operating days, with broader standards for twelve days. These are the so-called sound days. CM.com Circuit Zandvoort operates under a permit granted by the municipality of Zandvoort/OD IJmond under the Environmental Management Act.

Unsurprisingly, the emphasis in this permit is on the noise coming from the circuit. Strict enforcement of the noise produced by vehicles driving on the track, as well as the use of silencers, aims to reduce the noise from the track as much as possible.

Below you will find an overview of the noise forecasts and measurement results.

Regulations Noise Standards & Measurements

Rules that CM.com Circuit Zandvoort must comply with are laid down in a permit. Checking whether the circuit complies with this permit is carried out by the IJmond Environment Agency on behalf of the Municipality of Zandvoort.

CM.com Circuit Zandvoort uses a calculation model for the interpretation of the various operating days and the calculation of the noise production of the associated programme. Prior to an event, a forecast can be made based on previously collected data, which shows what the event will produce in terms of total noise average. This average may not exceed a limit set by the government agency.

The noise generated at CM.com Circuit Zandvoort is measured at a measuring point that is located directly next to the track (near the start of the straight). By measuring at this location, the effects of the wind on the sound are kept to an absolute minimum.

Daily Measurements

The noise production of CM.com Circuit Zandvoort is measured daily. These measurement results are translated by a computer into a final average, which should ultimately fall below the limit set by the Municipality of Zandvoort.

For the official events, CM.com Circuit Zandvoort is obliged to calculate the expected noise exposure in advance and to submit it to the Municipality of Zandvoort and the IJmond Environment Agency, who must make it clear that a proposed program fits within the permit conditions. During the events, the noise is constantly measured and the noise measurement results must be submitted to the government agency afterwards.

The noise standards for both the evening (19:00 PM – 23:00 PM) and the night (11:00 PM – 07:00 AM) are obviously substantially lower than the daily value. The permit explicitly prohibits motorsport activities on the race track at night (24-hour races with cars are therefore not allowed). By establishing an evening and night standard, the possibilities for use of CM.com Circuit Zandvoort are more limited than during the day.

UBO-days

The expected UBO-days in 2022 are:

  • 17 June
  • 18 June
  • 19 June
  • 24 June
  • 25 June
  • 26 June
  • 15 July
  • 16 July
  • 17 July
  • 2 September
  • 3 September
  • 4 September

Noise Prognosis

A calculation formula is used for the noise prognosis, in which several factors are taken into account. For example, one should imagine that every passage along the measuring point / microphone contributes to the total noise production to be measured. So if you enter in the calculation model how many cars will be driven, what the race distance (i.e. the number of laps) will be and what the noise production is per vehicle, this provides insight into what that specific race “supplies” from the available daily total. In this way one can compose a day program by “playing” with the different variables.
