What Does a Noise Barrier Cost per Square Metre?
Noise barriers in India are quoted per square metre of barrier face, and the rate swings widely with the material: roughly ₹4,000–₹14,000 per m² (supply) before foundations and installation. The right choice is rarely the cheapest per-m² number — it's the one that delivers the required noise reduction over a 25-year design life.
Noise Barrier Cost by Material
Three materials dominate Indian projects. Absorptive aluminium leads on acoustic performance and life; concrete is cheap but heavy; polycarbonate buys transparency at the expense of absorption.
What the Per-Metre Rate Should Include
A per-m² rate is only comparable when the scope matches. A complete installed noise-barrier price should cover:
- Acoustic panels at the specified STC and NRC
- H-beam steel posts, base plates and fixings
- Foundations / pile caps designed for wind load
- Corrosion protection (galvanising / powder coat) for 25-year life
- Transport, erection and site supervision
Supply vs installed: foundations, posts and erection commonly add 30–60% on top of a supply-only panel rate. Always confirm which you are being quoted.
How Height and Wind Load Change the Price
Two engineering factors quietly drive cost. Barrier height increases both panel area and the wind load the posts and foundations must resist. Wind zone (per IS 875 Part 3, up to ~120 km/h in Category I) dictates post section and foundation size — the structure below the panel can cost as much as the panel itself on tall, exposed runs.
Look at 25-Year Cost, Not Just the Quote
Concrete wins the supply-price line item but loses on installation (heavy foundations, cranes) and on acoustics (reflective, not absorptive). Aluminium absorptive panels on H-beam posts are lightweight, erect fast, resist corrosion for 25 years, and absorb rather than reflect — which is why they usually offer the lowest total cost of ownership on NHAI and metro projects even when the per-m² supply rate is higher.

Frequently Asked Questions
What is the cost of a noise barrier per square metre in India?
Supply rates typically run ₹8,000–14,000/m² for aluminium absorptive barriers, ₹6,000–10,000/m² for polycarbonate transparent barriers, and ₹4,000–8,000/m² for concrete. Foundations and installation usually add 30–60% on top.
Which noise barrier material is most cost-effective?
For most highway and metro projects, aluminium absorptive panels on H-beam posts offer the lowest 25-year total cost of ownership — lightweight, fast to erect, corrosion-resistant, and genuinely absorptive (NRC 0.85–0.95) rather than reflective.
Does the noise barrier price include installation?
Not always. Many quotes are supply-only. A complete installed price also covers steel posts, wind-designed foundations, corrosion protection, transport and erection — commonly 30–60% above the panel rate.
How much noise reduction does a barrier give?
A well-designed 3–5 m barrier typically delivers 8–15 dB(A) insertion loss at nearby receptors, depending on height, material absorption (NRC) and the geometry between source and receiver.
What standards apply to noise barriers in India?
Key references are IRC:SP:66, MoRTH Section 800, NHAI technical specifications, and IS 875 Part 3 for wind load. Environmental limits are set by the CPCB under the Noise Pollution Rules, 2000.
