Rumble strip sound volume comparisons

  • Car on bare pavement video clip, no narration (YouTube)
    Video shows a car approaching on a paved highway. The highway has centerline and edgeline rumble strips. A bird chirps at the start. The only audio is the sound of the car passing by and the sound from the wind. As the car heads into the distance, the vehicle sound softens. Video ends.
  • Car on sinusoidal rumble video clip, no narration (YouTube)
    Video shows a car approaching on a paved highway. The highway has centerline and edgeline sinusoidal rumble strips. The only audio is the sound of the car passing by. As the car gets closer, it passes over the centerline sinusoidal rumble strips. The sound this produces is a soft, staccato rumble. There is little, if any noise volume increase while the car drives on the sinusoidal rumble strips. As the car heads into the distance, the vehicle sound softens. Video ends.
  • Car on standard rumble video clip, no narration (YouTube)
    Video shows a car approaching on a paved highway. The highway has standard design, centerline and edgeline rumble strips. The only audio is the sound of the car passing by. As the car gets closer, it passes over the centerline standard rumble strips. The sound this produces is an easily-heard, staccato rumble. The noise volume seems louder than when the car passed over the sinusoidal rumble strips. As the car heads into the distance, the vehicle sound softens. Video ends.
