10-24. Determine the L₁0 noise level for the following highway traffic situation:
Autos = 2,000 per hour
Speed= 70 km/h
Speed= 70 km/h
Medium trucks = 200 per hour
Heavy trucks = 0
Observer-roadway distance = 60.0 m
Line-of-sight distance = 60.0 m
Barrier position = 5.0 m
1.0 m
Break in line-of-sight distance
Angle subtended = 160°
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

In preparation for a public hearing on a proposed interstate bypass at Non- troppo, Michigan (Figure P-10-25a), the County Road Commission has re- quested that you prepare an estimate of the potential for violation of FHA noise standards 75 m from the interstate. The city engineer has supplied sketch maps (see Figure P-10-25b) and data summary for your use.
