Remember that the noise monitors at Donington are linked to the local district council offices and they have the power to shut the circuit down if it transgresses its planning permission and the associated noise management plan.

If your car is too loud and you know it, please don’t come and risk the ire of the Local Govt Environmental Officer. And they have been known to turn up with hand held monitors. Please ensure that the track remains available to everyone to enjoy in the future.
THIS^^^^^^^^^

It is the local councils that insist on noise limits, not the tracks, which is why they try to help you on arrival, but have to boot you off if you are too noisy.
Too many noise complaints and the tracks WILL be closed down. The biggest problem for the tracks is the wind - sound carries a hell of a long way downwind.

Also, it is perfectly possible to get clamp on silencers if your car is too noisy and you know it. I have a set of 2.5 inch diameter silencers for my TVR, which take about 7db off the noise level on the static test. Google ACT TVR - they will fit any car with straight tail pipes and come in a number of sizes from peashooter to juvenile tosser. You can also get tail pipe inserts.

Finally, I found, when I turbocharged my TVR, the power increased by around 100 bhp, torque by nearly 200 ft lbs, and reduced noise by 10 db.

Just saying.

Mallory Park was closed down for approx 2 years for contravening it’s planning permission, partially as a result of a la k of control of noise issues and a lack of responsibility on behalf of the then operator.
New owners came in and had to renegotiate the planning permission and establish a new, and more stringent, noise management plan. And that is why there are far fewer test and race days than there used to be. And also why one Supercar experience company I have worked for stopped going there as some of its fleet of road cars were deemed to be too noisy and were stopped from running during a day that I was working at.
Similarly, Donington Park had to renegotiate it’s planning permission when it reopened after the Grand Prix fiasco of about 7-8 years ago and the new noise management plan had to be put in place.
Croft was also taken to court over transgressing it’s planning permission over noise issues, and originally lost it’s case, although this was subsequently Over turned on appeal.
Do you want to be the cause of trouble for the track day operator or the circuit operator? Do you want to take the risk of being thrown off a track day yourself?
Circuits may not have been closed down yet as a direct result of one or two noisy cars, but continuing noise complaints will help local residents build a case and the local government will have the power to act.
We all have a responsibility to act responsibly

Do you not understand the irony that planes which are generally louder than cars are able to fly all day without issue?

I have no problem with noise limits , but the question of where the meters are , is fair enough. The circuit doesn't care if you make noise elsewhere, only at the meters as that is only what is measured!

As an aside, and off topic - At what point do you tell the residents to fk off? They moved to the area around a race circuit, the race circuit was there before the residents were.

I wouldn't move to an area near an airport, and then complain about noise. I would expect to be told to fk off.

Yes I must say I found it rather baffling at Goodwood that they had a Spitfire flying around that was SO loud, yet the cars are held to the 101db drive by limit.

Also agree that it seems very unfair that someone can move near a circuit then complain enough to get it closed!

A point well made, and the aircraft taking off from East Midlands Airport directly over the track at Donington make a joke of car noise complaints.
However, we are measuring the noise of one car at 101-105 dB. But 40 cars on track together must make a considerable amount of noise, and to those living downwind of the circuit, it must be annoying. I seem to remember they are building new houses close to Donington - that will cause problems.

It also seems strange to me that Mallory Park had so many problems, being in a natural hollow and in the arse end of nowhere, ditto Bedford Autodrome, but my car nut friend who lives five miles downwind of Snetterton says you would be surprised how noisy it is in his garden on a track day.

I live 800 yards downwind of the A1, which I can hear anytime I have a window open on the west side of my house, 24/7 - perhaps i should get a petition up to have the road closed? My house was built in 1855, so I would seem to have the upper hand here.

It’s an argument I hear all the time. But there are big differences, and there are issues. And the aviation industry is highly regulated to help mitigate noise.
And I will just set out the differences as I hear them explained to me. And remember that I am a racing fan, and competitor who moved to Castle Donington precisely because of the track so don’t shoot the messenger.

The airport utilisation is actually as low as 18% and an aircraft takes off and makes a noise for a very short period of time compared to the gaps to the next aircraft so there are actually long periods of quiet between aircraft. In contrast the track operates all day between 0900 and sunset many days of the week and there tends to be a consistent and persistent noise.
So, it’s not really the peak noise that irritates the locals, it’s the persistent noise.
The track is also used much more now than years ago because of the growth in track days.

It doesn’t bother me, as I say I moved to the area precisely because of the track, but I do think that the track has to be seen to be a good neighbour.
Yes, I firmly agree that people should not move near an airport/ track and then moan - I told someone that only last week - but I also think that we all have a responsibility to play by the rules and do our bit to ensure that the track does not receive complaints and does stay open so that we can continue to enjoy it.
As a result I do think that just slowing down near the noise monitors is irresponsible and selfish. All that will happen is that people will complain and DP will fit more noise monitors etc.
Our sport is an easy target and we all need to do our bit to make sure that we don’t give the complainants the ammunition they need. Fine to tell someone who moves to near a race track and then moans to f**k off, but equally I think it’s fine to tell someone to f**k off who deliberately drives a car that they know is above the noise limit on the track and flouts the rules by slowing down near noise monitors because they are both risking my sport.
The noise limits on track are NOT the noise limits at two specific points, they are the noise limits for the circuit operation, and just happen to be monitored at two points currently. They could easily be monitored at a lot more points and I have been at the circuit when “spectators” have been there with mobile noise meters at other parts of the circuit.
Play nicely. Observe the rules. Preserve our sport!

From what I read it's just after the chicane where you're hard on the gas accelerating onto the pit straight, or at least that's the bad one.

I did a trackday there in my Sports 1000 race car and was pleasantly surprised to have no issues at all, all I did was modify the exhaust to accept a removable 90deg bend tail pipe, thus aiming exhaust gases at the ground. I am certain without that I would have had problems.

This is with a high revving bike engine, short manifold and straight through silencer pointing directly out the side of the car towards the pit wall!!

well. i can confirm 0 issue, i didn't have to lift off or anything. Plenty of cars louder still with no issue.
so, at least we know any bmw M car or anything with a straight 6 and M performance exhaust is absolutely fine

There was also plenty of silence on Tuesday evening - too many reds!

Fun evening though - good to be back on a trackday

I had a fun walk in the woods with my dogs at lunchtime.
Peaceful, wind in the trees, bird song, the patter of excited paws and then

WHOOOSHHHHHHH

Too many reds....well the right number, actually, in tight formation, on their way home at 200 feet to Scampton
