In this audio, the dominant sound is of a vehicle moving along a road. The steady hum of the engine and the periodic whoosh of passing air give a sense of speed. Suddenly, the rhythmic rumble of tires on asphalt is interrupted by a jarring crunch and a brief, sharp vibration that reverberates through the audio, indicating the vehicle has hit something. This is followed by a momentary decrease in the engine's noise, possibly indicating the driver has eased off the accelerator. The car's shock absorbers can be heard working overtime to absorb the impact, creating a brief, bouncing effect. Then, the regular sound of the vehicle moving smoothly on the road resumes. The whole sequence gives the impression of a car unexpectedly hitting a pothole in the road.
