The audio begins with the distinct sound of a key turning in the ignition. The listener can then hear the deep rumble of a 2007 Dodge Diesel Truck's engine coming to life. It starts with a low growl, a signature characteristic of a diesel engine, which gradually builds up to a full-throated roar. The audio provides the listener the experience of being right in the truck's cab, providing a realistic and immersive experience. The soundscape is pure and raw, with the engine's powerful vibration adding a layer of depth to the acoustic experience. This sound effect, or SFX, is reminiscent of the grit and power associated with diesel trucks, capturing the essence of a start-up that is unique to this type of vehicle.
