Just a friendly reminder that we haven’t conducted noise testing at our events for a while and……
……Noise is always a consideration at any Motorsport Venue and becoming more and more of a volatile topic.
Noise testing is very likely at the Coffs Coast Tarmac Autocross 2025 event HINT! HINT!
If your over the limit, sadly, you won’t be allowed to compete until its rectified. That includes pops, bangs, squeals and/or rattles!
If your not sure, there are some phone apps which will give you a rough idea (like Decibel X, Android & iOS)
The Coffs Sporting Car Club and Raleigh international raceway have sound meters and are happy to test your vehicle for you before the event.
Static: Test at 45 deg 500mm away from tip at 3500rpm (guide only)
Regulations: 30m from track edge must not exceed 95db.
