These days, all racing circuits have noise restrictions. It is extremely important that we operate in compliance with our set limits. We must act in accordance with the regulations to ensure the future of track days for everyone that abides by the rules. Please help us by making your vehicle as quiet as possible before taking part in any on circuit activity. Anyone wishing to have their car tested before a track day is more than welcome to come to one of our circuits during our events and have a noise test free of charge. It takes just a few minutes.
The initial test is a static test which is carried out using a handheld meter. Each car is measured 0.5 meters away from the exhaust at a 45-degree angle when the engine is being held at ¾ of the maximum RPM. In cases where the vehicle has two separated exhausts, the measurement will be taken as below from the median point between the two.
For car track days, the noise regulations for each of the circuits are as follows:
|Oulton Park||Cadwell Park||Snetterton||Bedford Autodrome|
|Indy Circuit (daytime) - 105dB(A)||All circuits - 105dB(A)||All circuits - 105dB(A)||Daytime - 105dB(A)||All circuits - 101dB(A)|
|Indy Circuit (evenings) - 102dB(A)||Evenings - 102dB(A)|
|*Some events run at 98dB(A)|
|Grand Prix Circuit - 101dB(A)|
Factors such as air temperature and humidity can affect the level of noise that your car is producing. If you are ever within 1dB(A) of a particular limit then we suggest that you strongly consider having your car looked at before making another booking.
