Metal, Transparent Polycarbonate, Temporary & Concrete Noise Barriers for Highways, Railways, Plants & Construction Sites
Summary: A noise barrier is a solid wall placed between a noise source and the people it affects, blocking the direct sound path. This page is written for highway and railway contractors, plant managers and EHS teams who need a noise barrier designed for their site and built to CPCB and state pollution control norms.
We start every project with a site assessment, then design, fabricate and install the barrier system ourselves, end to end.
- Metal, polycarbonate, temporary and concrete barriers
- Proven on elevated railway corridors
- ISO certified manufacturer · 150+ projects delivered
SomNandi Industries designs, fabricates and installs noise barriers in India for highway corridors, railway flyovers, plant boundaries, construction sites and residential zones. Our range covers metal noise barrier panels, transparent polycarbonate noise barriers, temporary construction noise barriers and concrete sound barrier walls, each designed around your site rather than pulled from a generic catalogue and built to meet CPCB and state pollution control norms.
Why Highway, Railway and Boundary Noise Needs an Engineered Noise Barrier
When noise from a highway, railway, plant or construction site creeps past acceptable levels, and a highway noise barrier or boundary wall is the only practical fix, the people affected are usually beyond your fence: residents, schools and hospitals nearby. Complaints, stop-work notices and compliance problems follow.
A properly designed barrier blocks the direct path between the source and these receivers. To work, it has to be high enough, long enough and continuous, with no gaps, and it has to stand up to wind, weather and vibration for years.
What Is a Noise Barrier?
A noise barrier, also called a sound barrier wall or acoustic barrier, is a solid structure that breaks the line of sight between a noise source and a receiver. SomNandi manufactures four types: metal noise barriers with high sound transmission loss and corrosion-resistant coatings for boundaries and perimeters; polycarbonate noise barriers that are transparent, lightweight and UV-resistant for railway bridges and flyovers; temporary noise barriers that go up fast with no foundation for construction sites and events; and concrete noise barrier walls for permanent, high-mass attenuation on highways and industrial boundaries.
Metal vs Concrete vs Polycarbonate Noise Barriers: What Actually Changes?
Short answer: Metal is lighter and quick to install along boundaries; concrete gives the most mass for heavy traffic or industrial noise; polycarbonate keeps the view open and adds little load to bridges; temporary barriers are reusable and need no foundation.
The right choice depends on the noise source, the site, the structure the barrier is mounted on, and how long it needs to stay. Many projects combine types along one route.
How Does a Noise Barrier Reduce Noise?
Short answer: By blocking the direct sound path, so noise has to bend over and around the barrier to reach the receiver, losing energy as it does.
Performance depends on height, length, continuity and the barrier’s mass. Gaps at the base or between panels let sound leak straight through. The achievable reduction depends on the barrier type and site conditions, which is why we work it out during the site assessment instead of promising a number upfront.
Engineering Design and Construction Approach
Every SomNandi noise barrier project starts with a site assessment, not a sales pitch. From there we design the barrier type, height and alignment; engineer foundations around your site’s soil and wind conditions for permanent barriers; fabricate the panels; and install them with our own team. Where a barrier alone will not solve the problem, we pair it with acoustic enclosures, acoustic louvers or sound attenuators at the source.
Field Notes: Where Noise Barrier Projects Go Wrong
Most underperforming barriers are too short, end too early, or have gaps at the base and between panels, so sound simply goes around or under them. The other common issue is foundations or fixings not designed for local wind load or bridge vibration, which leads to damage and loosened panels within a few seasons.
Technical Specifications Overview
| Barrier Type | Typical Use | Performance Advantage |
|---|---|---|
| Metal Noise Barriers | Plant boundaries, highway corridors, industrial perimeters | High transmission loss, corrosion-resistant, low maintenance |
| Polycarbonate Barriers | Railway bridges, flyovers, view-sensitive sites | Transparent, lightweight, UV and weather resistant |
| Temporary Barriers | Construction sites, short-term events | Fast to install and remove, reusable, no foundation |
| Concrete Barrier Walls | Highways, industrial boundaries, residential edges | Highest mass attenuation, decades of life |
| Foundations | Designed for soil and wind conditions | Long-term structural stability |
| Compliance | CPCB and state pollution control norms | Meets regulatory requirements |

Specifications, Benefits, Applications and Installation Process for Noise Barriers
Compliance With CPCB Noise Standards
Under the Noise Pollution (Regulation and Control) Rules, 2000, CPCB ambient noise limits are 75 dB(A) by day and 70 dB(A) by night in industrial areas, 65 and 55 dB(A) in commercial areas, 55 and 45 dB(A) in residential areas, and 50 and 40 dB(A) in silence zones around hospitals, schools and courts. Day time is 6 a.m. to 10 p.m. SomNandi designs every noise barrier against the limit that applies at the nearest receiver, in line with CPCB and state pollution control norms.

Frequently Asked Questions
It depends on your site. Metal is lighter and faster to install along boundaries; concrete gives more mass and better reduction for heavy traffic or industrial noise.
Yes. They are built for vibration resistance and weather durability while staying light enough to mount on bridge structures.
Usually within days. No foundation work is needed, and the same barriers can be relocated when the project ends.
Yes. We design foundations around your site's soil conditions and wind load.
It depends on the barrier type, height and site conditions. We calculate it during the site assessment rather than promising a figure upfront.
Often, yes. Pairing a barrier with enclosures, louvers or attenuators at the source usually gives better overall control.
Yes. We cover industrial plants, highways, railway corridors and construction sites.
