10-23. Determine the Lio noise level for the following highway traffic situation:
Autos = 1,500 per hour
Speed = 60 km/h
Speed= 60 km/h
Medium trucks = 150 per hour
Heavy trucks =0
Observer-roadway distance = 40.0 m
Line-of-sight distance = 40.0 m
Barrier position = 3.0 m
Break in line-of-sight distance = 6.0 m
Angle subtended = 170°
Answer: L10 = 51 dBA
