No idea why it was so difficult to find that, it's nowhere on the NCM site.

Sound Limits
:
NCM retains the right to impose noise restrictions on participating cars, motorcycles and karts. While no specific noise restrictions are to be enforced without NCM’s written notice, NCM may at any time and at its sole discretion, choose to impose a noise control system. Such limits are likely to be similar to those operated by the Sports Car Club of America at their National race events. These require that vehicles comply with a sound pressure level of 103db “A” frequency weighted (dba) measured on a fast response setting at 50ft (=/-2 feet) from the edge of the track pavement. (See SCCA 2005 GCR’s Section 12)

We were running a soundmeter at our local autocross today, I was surprised how loud 98db is. Though some cars really set it off where earsplittingly loud go-karts were well within the limits... All in tone of sound, I guess. 103db is pretty loud from 50ft lol.

I can let you know exactly how loud 105+ db is, lol.

I got my hotel reservations all set. I need to go through and sign up for the events. Probably knock that out this week sometime.

We must have some slack asses seeing as there is still only 13 people registered...
