Traffic Noise FAQ Section
Q: How much does traffic noise typically decrease with your barriers?
A: Our barriers can reduce traffic noise by 10-15 decibels on average. The exact reduction depends on factors like barrier height, distance from the road, and installation angle. For highways with constant heavy traffic, we recommend our commercial-grade barriers which provide the highest noise reduction.
Q: What's the best height for traffic noise barriers?
A: For most residential applications near busy roads, 8-foot barriers provide optimal noise reduction. Taller 10-foot barriers are recommended for properties located downhill from roadways or in areas with significant truck traffic. Our engineers can assess your specific situation to recommend the ideal height.
Q: How do these barriers handle different types of traffic noise?
A: Our barriers are designed to mitigate various traffic noise sources: engine sounds (low-frequency), tire noise (mid-frequency), and horn/brake sounds (high-frequency). The multi-layer construction combines mass, absorption, and diffusion to address all frequency ranges effectively.
Installation Guidelines
Proper installation is crucial for optimal noise reduction performance. Here are key considerations:
- Barriers should be placed as close to the noise source as possible
- Maintain a minimum 4-inch gap between panels and ground to prevent moisture damage
- Concrete footings should extend below frost line for stability
- Angled panels (5-10 degrees) can improve sound deflection in certain situations
- Consider existing landscaping and drainage when planning installation
