Unfortunately not this year.
I would have to go to one of Donny unsilenced days I think first, and get measured for sound there while I'm at it.
My car is way quieter than when I went last year, and was asked to leave soon after beginning because I substantially smashed their conservative 98db driveby limit

..Rigorously automatically computer enforced!
Many other track days are 105db, and I would have passed the 98db static test if it was taken, but driveby results are very environment dependent.
I'm not sure is the placement of the sound monitering stuff on the exit of a 2nd gear corner picking up some induction noise from the supercharger probably at max rpm.
Somebody was telling me that apparently there can be random spikes of noise due to the sound reflecting under the car from the s/c and back towords the listening source.
Its a hell of a track though, I loved all of the measly 6 laps I got in

(3 of these being no-overtaking warmup ones..)
Cheers,
TB
