The data must be related to the position of the microphone in SPB measurements: 7.50 m away from the middle of the right lane and at a height of 1.20 m above ground. Additionally the data must be at a velocity of 80 km/h for heavy trucks and at 90 km/h or 110 km/h for passenger cars (cf. below). The data must not be weighted!
velocity:
90 km/h for passenger cars, 80 km/h for heavy trucks 110 km/h for passenger cars, 80 km/h for heavy trucks
