In addition to the initial static test, our circuits have a continuous automated 'drive-by' meter operating to ensure vehicles continue to adhere to the noise restriction in place.
If the results of the drive-by monitoring show that your vehicle is exceeding the drive-by then you will be called into the pit-lane to address the noise level being generated.
The circuits drive by limits are:
- Anglesey 101dB (77dB on quiet days)
- Bedford Autodrome 87.5dB
- Brands Hatch 92dB
- Bruntingthorpe 87.5dB
- Cadwell Park n/a
- Croft 70dB (average over an hour)
- Donington Park 98dB
- Goodwood 101dB (96dB with over 9 cars)
- Knockhill n/a
- Lydden Hill n/a
- Mallory Park n/a
- Oulton Park 92dB
- Modello Park n/a
- Pembrey n/a
- Rockingham 103dB
- Silverstone 102dB
- Snetterton n/a
- Thruxton n/a
Exhausts do get louder with age as the packing deteriorates and it may be that you need to purchase an additional silencer or have the exhaust repacked before attending another event.
