98 db noise limit
Is that 98dB or 98dB(A) as it makes a heck of a difference? Also at what distance is it measured?
If measured by the MSA method it's 1m from the exhaust at 75% of engine maximum rpm (at an angle of45 dgrees)
I'll take the anorak off now!
Seriously if anyone needs any vehicles noise tested pror to circuit use, then I may be able to help.
