Effective Traffic Noise Reduction with Advanced Noise Barrier Solutions
The long awaited Jalan Tun Razak flyover is finally opened to the public, bringing much needed relief to one of Kuala Lumpur’s most congested corridors.
The 2.8km three lane elevated road stretches from in front of the Royal Selangor Golf Club all the way to the Kampung Pandan roundabout with additional connectivity to the Jalan Bukit Bintang exit and the MEX highway interchange.
What many motorists may not notice is the noise barrier wall installed along the flyover. Pertac Resources was engaged to supply and install this noise barrier as part of the infrastructure project, helping to shield the surrounding community from the traffic noise exposure that a busy flyover often produced.
This newly completed flyover on Jalan Tun Razak is designed not only for smoother traffic flow but also for effective traffic noise mitigation.
For this project, we have installed PerMAP metal noise barrier wall, designed to keep traffic sounds at bay and make the surrounding areas more peaceful.
Why Traffic Noise Reduction Matters in City Areas
Traffic noise is more than just an annoyance, it can affect health and wellbeing. Long term exposure to traffic noise can often lead to stress, poor sleep, and most of the time difficulty in concentrating.
Elevated highways and flyovers often present a unique acoustic challenge compared to ground level roads.
Because the noise source is raised above the natural ground level, sound radiates more freely across a wider area, reaching upper floors of nearby residential and commercial buildings that would otherwise be shielded by terrain or existing structures.
Without mitigation, road traffic noise from a flyover of this scale with thousands of vehicles per day across the three lanes can consistently exceed 70 dB(A) at nearby facades.
A well designed noise barrier along the parapet of the flyover is one of the most effective and practical countermeasures, deflecting and absorbing sound before it propagates into the surrounding neighborhood.
By utilizing well designed noise barriers, it can help with:
- Reducing the impact of vehicle noise on nearby residents and businesses
- Enhance environmental quality along busy roads
- Promote sustainable urban development
PerMAP Metal Noise Barrier Wall: Optimal Acoustic Performance
For infrastructure projects such as highways, flyovers, and LRT/MRT corridors, we typically propose our PerMAP Absorptive Metal Noise Barrier Panels.
The PerMAP system is designed specifically for outdoor road and rail environments, combining a weather resistant outer metal shell with a high density sound absorbing acoustic infill.
This twofold design both blocks sound transmission and reduces reflective noise that can otherwise bounce back toward opposing buildings.
Our PerMAP metal noise barrier wall is engineered to deliver superior noise reduction.
Key benefits include:
- High sound attenuation which effectively minimizes traffic noise for sensitive areas.
- Durability and low maintenance where it is engineered to withstand harsh weather conditions.
- Customizable aesthetics to blend into urban landscapes without compromising design.
Complementary Acoustic Barrier Solutions
For situations where maintaining clear view and aesthetic design is a priority, our PerGLAS® Transparent Noise Barrier Panels offer a high performance acoustic solution without obstructing views.
For diverse project requirements, we also provide Soundblox concrete block walls which are ideal for heavy duty applications with maximum sound insulation performance.
Learn how our PerGlas and Soundblox solutions enhance traffic noise control and deliver robust sound attenuation.
Proven Results for Quieter Cities
The Jalan Tun Razak flyover demonstrates the result of effective noise barrier systems in reducing urban traffic noise. By addressing noise at the source, our solutions create a comfortable environment for city residents while preserving infrastructure aesthetics.
Beyond reducing traffic jams at the Kampung Pandan roundabout during peak hours, the flyover is also intended to eventually link up with the Setiawangsa-Pantai Expressway (SPE), further expanding its role in KL’s highway network and reinforcing the long term need for sustained noise management along the road.
