The Actros was wired up using a pair of DPA 4060s in the cabin, a DPA 4061 and a Sennheiser MKH8040 on the engine, and a second Sennheiser MKH8040 on the exhaust. These mics were plugged into the Sound Devices Mixpre-6 and 633 recorders. Each perspective sounds different and can be layered for creative vehicle sound design. The recordings cover more than 32 minutes of driving on country roads and on motorway. There are two engine starts and stops, idling, accelerating, decelerating, driving slowly and driving fast.
The cabin DPAs sound muffled, as you would expect from a truck with good sound insulation. This perspective includes occasional indicator clicks and power seat movement. The engine perspectives sound meaty and occasionally bright, including a good deal of creaks and other metal rattles caused by the elements that connected the tractor unit to the trailer. The exhaust perspective is a little more muffled and bassy, exactly as you would expect. These 3 perspective also include the typical high speed hum associated with long-haul trucks.
