New Noise Levels At Knockhill

[4Hero]

From their site "We have a noise limit of 105db(A). The noise reading is measured statically at 0.5 metres at 3/4 revs."

Not sure if this will affect anyone here.

Would be surprised if it didn't!

[colin_ross]

Uh oh.

[thefastone]

now, that didn't sound good mate...

Anyone got a decibel meter, bit of a bummer considering your on top of a hill in the middle of nowhere.

Me, 107.8 db

or 101.1 with the bung fitted.

I see from the link, it's for Top Marque events.

Not sure how it will affect JohnS SIDC or Track Scotland events.

With all the houses that surround the circuit they must have been getting sackloads of complaints about all the noise.

It's in the middle of nowhere, what are they playing at.

I'm no fan of loud exhausts on public roads - when I hear them going past my house I want to reach inside their windows and rip their good-for-nuthin' shielded-by-Burberry eyes from their too-close-together sockets. HOWEVER - surely just about anything should be good to go on a race track?

Freakin' H&S, I'll bet...

[RS Grant]

This is a bad thing and I think that a lot of people will fail these tests, not just Subaru owners but there are LOTS of different makes which tend to be loud as fook once you stick an exhaust system on.

How do they rule against cars that are running big boost with ext. wastegates and screamer pipes, surely a screamer pipe is putting out pretty severe dB but wont show up if you're just revving it standing still as its designed to operate under load. Unless they're going to monitor it constantly throughout the trackday at a set point on the circuit and black flag 'offenders' with loud cars, this is flawed rule.

Cheers,

Grant

I got a digital noisemeter if anyone wants a test to be sure to be sure.

Only a fiver a go

I always thought it was 0.5mtrs away at a 45 degree angle holding the revs at 4K, correct me if i is wrong.

Yes please Davie, first dibs on a go of the Db meter. A fiver sounds about right but you can pay me more if you really want.

How about a tenner then Col, just for your humour!!!

No probs guys anytime, just PM me and i will see if i am in your area and will pop round or if anyone is in the Rutherglen area then let me know.

I always keep it in the car for works purposes anyway.

[colin_ross]

It's a deal. That'll make up for you skipping your round at Banbury.

I'll head over in the next week or two and get the bad news. Hope your neigbours are understanding like mine.

Now officer, if you wouldn't mind placing your head inside the tailpipe, you'll find that the noise levels really are quite muted...
