Noise: Static & Drive-by

PostPost by: The Old Italian » Fri Mar 04, 2011 9:15 am

Over in the Elan lounge I've posted a question as to where I can find a track prepared Elan suitable for trackdays, but it's just occured to me that maybe exhaust or induction noise on a non-standard car
would rule it out at circuits that have unsympathetic noise limits.

I know that the specs will vary but can anybody please share their noise testing results
so that I can get a spectrum of what to expect.

Thanks.
Ian.

Ian,

I see you have no replies yet, so FWIW, I remembered posts in the archives wrt measurement issues and grief with a "standard car" at Castle Coombe.

Hopefully things have improved since then..no doubt others will be along soon to update on current practices...

HIH Cheers - Richard

If you point the exhaust tip toward the ground it helps lower

Thing is if you do that in a paddock that is dusty, you really hack off your neighbour - the dust goes everywhere.
