101DB static and 87 DB drive by.
I know mine at SVA was 95DB, not sure what it would be at drive by. But digging about, you can take the car there to be tested.
So if I get a good break in the weather next weekend, I give them a call to see if I can pop along to get the car tested!
And free of charge.
