if this is a quite day it's 98db ride by. there are a couple of mics on track, not sure where.
the day i did there on the sd i got black flagged 3 times, with baffles in (akros) the baffles are the wrong type (open ended) and are too loud you need a baffle that has the end plugged and the tube with holes (if that makes sense).
the open type baffle that come with akros don't do a lot, think my 1st flag was 103db. the on site mechanic had a look to see if he had a baffle to fit my cans. he didn't so took my akro ones out, and without asking if it was ok, hammered the ends closed. still got black flagged, next time was 102db.
i had a go at closing the other end of the baffle, and talked my way out of an early home time, 3rd time lucky, black flagged. i didn't find out what the last noise level was as it was near the end of the last session.
donny are getting much more strict with the noise as they're having trouble with the coucil trying to limit how much the track gets used.
