Highway Acoustic Noise/Sound Barrier Wall
Noise is unwanted sound that can disturb daily life and affect the surrounding environment. These barriers are structures designed to reduce this noise, particularly along busy highways. At Utkarsh India, our noise barriers help block or absorb traffic noise, protecting nearby communities and creating a quieter, safer environment.
Transparent or reflective highway acoustic barriers offer several benefits, particularly for urban and highway applications. They protect nearby communities from high traffic noise while maintaining safety and clear visibility, preserving the natural landscape and ensuring infrastructure blends seamlessly with its surroundings. Their lightweight and efficient design makes them ideal for bridges or extensions over concrete walls without adding extra structural load. Additionally, they provide a cost-effective alternative to full concrete barriers, combining performance with aesthetic appeal.
At Utkarsh India, we design highway noise barrier solutions to suit the material type, project scale, and environmental needs, delivering durable, high-performance solutions that create quieter, safer, and more comfortable surroundings.
Types of Noise Barrier
Reflective Noise Barriers
A Reflective Noise Barrier is a sound control structure designed to deflect and redirect noise away from residential or sensitive areas instead of absorbing it. Made from durable materials like solid or multiwall polycarbonate sheets, these barriers are highly effective along highways, bridges, and urban roads where maintaining visibility and aesthetics is important. Their smooth, transparent surface reflects sound waves back toward the traffic source while allowing natural light and clear visibility, making them a practical and visually appealing solution for modern infrastructure projects.
Features of Reflective Noise Barriers
Panel Thickness: Available in a different range from 8mm to 20mm, allowing flexibility based on noise levels and project requirements.
Sound Transmission Class: Measures how well the barrier is effective in sound control with ratings between 18 dB to 26 dB.
Airborne Sound Insulation: Indicates how much sound is absorbed rather than reflected; range from 18dB to 30 dB, ensuring quieter surroundings for the nearby area.
Absorptive Barrier
Absorptive Noise Barriers are specially constructed using rockwool or glasswool insulation layered between metal sheets. These materials effectively absorb and dampen sound waves, preventing them from reflecting back into the environment. The application of this product is based on the material composition or specific project requirements, ensuring customised acoustic performance for each installation.
Features of Absorptive Noise Barrier
Panel Thickness: range from 100mm to 150mm, providing strong sound absorption and structural stability based on project needs.
Sound Transmission Class: Ability to block sound; ranges between 20 dB and 45 dB, ensuring a significant reduction in noise transmission.
Airborne Sound Insulation: It measures how efficiently the barrier absorbs airborne noise; it ranges from 18dB to 45dB, creating a comfortable environment near highways and urban zones.

FAQs
Highway noise barriers, also known as sound barrier walls, acoustic barriers, or noise walls, are exterior structures designed to shield nearby residential or commercial areas from excessive traffic noise.
Yes, transparent highway noise barriers made from polycarbonate or acrylic materials are effective and aesthetically appealing. They maintain visibility and natural light while reducing traffic noise levels efficiently.
Common materials used in highway acoustic barriers include metal sheets, aluminium, polycarbonate panels, concrete, and rockwool insulation. These materials are selected based on sound absorption capacity, durability, and project requirements.
The height of a highway noise barrier wall generally ranges between 3 to 6 meters, depending on the road design, traffic intensity, and the required level of sound reduction for the surrounding area.
The primary function of a highway noise barrier is to reduce the transmission of traffic noise from busy roads into nearby residential, commercial, or sensitive zones such as schools and hospitals.
Noise barrier walls are typically installed along highways, expressways, flyovers, railways, and industrial zones to protect nearby communities from continuous noise exposure.
Reflective noise barriers redirect sound waves away from populated areas, while absorptive noise barriers absorb sound energy to minimize reflection. Both types are used depending on the project’s acoustic and environmental needs.
The design of sound barrier walls involves factors like material density, barrier height, panel thickness, and placement angle. These parameters ensure maximum noise reduction and durability in varying environmental conditions.
Utkarsh India offers high-quality highway acoustic barriers engineered for long-term performance, weather resistance, and aesthetic appeal. Our customized designs ensure effective noise control for highways, bridges, and urban infrastructures across India.
