Hey, i was told that the legal noise level for a car was 100db, my car is 101db in the cab, and winds the meter off the scale just about when put at the rear of the car, can anyone tell me if 100db is correct and how they judge it from, like 10 feet away or at the back of the car.
any help appreciated cheers |

all the qld transport guide says is
exhaust systems must continue to comply with relevant legislation or Australian Design Rules for vehicle noise.

I'm not sure where they measure it from, but i thought it was around 90-94 dB. My guess would be that, its measured from around the car, probably from behind and about 20 feet away???

they put the microphone a feet away from the tip of the exhaust and reved it at around 2500-3000rpm.

For a modified vehicle in NSW for an engineers report you must have tested to the relevant ADR. Depends what vehicle type and year model as to which ADR must be complied with. 28/00 specifies a driveby test and 28/01 a driveby and a stationary noise test. (Cant remember the driveby limits off the top of my head), but it is 90dB for the stationary for cars that required 28/01.
If I got pulled up for noise based on a stationary noise test and my vehicle only required a driveby I would challenge them on this point.
