| Not seen the noise police out on track as it were at Oulton or similar setup to Donny with a mike on the start finish straight.
Must admit the noise mularkey can be a bit of a lottery all sorts of factors outside yer control can affect the reading, proximity of buildings, background noise.
Who does the test? Circuit staff or local environmental bods from the council.
The MSA used to employ Noise officials who knew their stuff and had set guidelines to work to regarding the test, i.e. open area for so many metres around the test area, standard distance and angle from the exhaust outlet for noise meter to be held and so on but this was just for a static test.
A "drive by" test is a different ball game but only Donny and Goodwood are set up for this AFAIK. Other circuits rely on the MK1 ear drum out on the circuit to decide if a static test is called for if noise is a concern.
