| 摘要： | Noise from vehicles passing over rumble strips is a major source of complaints from residents living adjacent to highways in Washington state. This project evaluated wayside noise levels from various centerline rumble strip designs to determine overall sound levels and 1/3-octave band frequencies. Results suggest that some designs have lower exterior sound levels and sufficient interior sound levels. However, the effects of specific design variables on exterior noise levels were inconclusive and suggest that interactions among variables contribute to exterior sound levels. |
