Noise Barrier Manufacturer in India | Ecotone
Quick Answer: Ecotone Packsound is a noise barrier manufacturer based in Greater Noida, India, building metallic, polycarbonate, and mobile noise barrier panels for highways, railways, DG sets, and factories. Panels deliver STC 30 to 40 and NRC up to 0.95, cut traffic and machine noise by 10 to 20 dB at the receiver, and are engineered for engineers, contractors, NHAI project consultants, and facility managers who need CPCB-compliant, IRC-referenced noise control on live sites.
What Is a Noise Barrier?
A noise barrier is a solid, sound-blocking wall or panel system placed between a noise source, such as a highway, railway line, or DG set, and the people it affects, so that sound energy is reflected or absorbed instead of reaching homes, hospitals, and schools. It works on a simple physics principle: sound cannot pass through a dense, continuous mass without losing most of its energy, and a barrier tall and long enough to break the direct line of sight between source and receiver can cut perceived noise by roughly half. In India, noise barriers are most visible along elevated highway stretches, metro corridors, and around DG rooms in commercial buildings, where the Central Pollution Control Board enforces ambient noise limits under the Noise Pollution (Regulation and Control) Rules, 2000.

Ecotone Packsound, Noise Barrier Manufacturer for Highway, Rail, and Industrial Projects
Ecotone Packsound is a noise barrier manufacturer in India serving highway EPC contractors, NHAI-empanelled consultants, metro rail agencies, factory owners, and residential societies located near arterial roads. If you are specifying a noise barrier on highway medians, boundary walls near a genset yard, or a temporary noise barrier for a construction site, this page is built for that decision: it covers material selection, real acoustic performance data, installation sequencing, and the gap between marketing claims and site reality, based on projects we have executed, not just catalogue promises.
What Does a Noise Barrier Actually Reduce, and By How Much?
A well-designed noise barrier panel typically reduces perceived noise by 10 to 15 dB at the nearest receiver, which the human ear experiences as roughly a 50 percent drop in loudness. Reduction depends on three site factors more than on the panel brand: barrier height relative to the sightline, barrier length beyond the protected zone, and the gap between panel base and ground. A barrier with even a 50 mm ground gap can lose 3 to 5 dB of its rated performance, which is the single most common installation error we see on Indian highway sites.

Why Choose Ecotone as Your Noise Barrier Manufacturer?
Most noise barrier manufacturer pages list features. What actually decides whether a barrier performs on site is the sequence most vendors skip: a baseline dB reading before fabrication, panel selection matched to whether the dominant noise is low-frequency traffic rumble or high-frequency machine whine, and a joint-sealing detail at every panel-to-panel and panel-to-ground junction. We have corrected barriers on live highway stretches where the panel spec was correct on paper but the ground gap alone was erasing 4 dB of rated performance. That is the gap between a noise barrier panel that looks right in a brochure and one that measurably works after handover.
- Decades of acoustic engineering experience across highway, rail, and industrial noise control
- In-house acoustic modeling before panel fabrication, not after
- Metallic, polycarbonate, and mobile noise barrier ranges under one manufacturer
- Nationwide project delivery and site support across India
Frequently Asked Questions:
No. They reduce it by 10-15 dB, not to complete silence.
Metallic panels with acoustic core suit highways; polycarbonate suits visibility-critical stretches.
Height depends on sightline between traffic source and nearest receiver.
Reduction is highest on the shielded side, lower on the source side.
STC 30 to 40 is typical for highway and industrial applications.
Quality galvanized or coated panels typically last 15-20 years outdoors.
Yes, even a small gap can leak significant sound underneath.
They give lower but useful reduction for temporary construction sites.
CPCB sets 55 dB day and 45 dB night for residential zones.
Facility managers, EPC contractors, and factory owners near DG sets.
