How Much Does an Acoustic Enclosure Cost in India?
The honest answer is: it depends — but not as vaguely as most vendors make it sound. A DG-set acoustic enclosure in India can cost anywhere from about ₹50,000 for a small canopy to ₹15,00,000+ for a large walk-in acoustic room, and the difference comes down to a handful of measurable factors: generator size, the noise reduction (insertion loss) you need, panel construction, and whether installation is included.
This guide breaks the price down the way an engineer would, so you can sanity-check any quotation you receive and budget with confidence rather than guessing.
What Actually Drives Acoustic Enclosure Price
Five variables move the number more than anything else. Understand these and you can read any quote critically:
- Insertion loss required — the gap between the DG set's raw noise (~95–105 dB(A)) and your target (75 dB(A) at 1 m for CPCB) sets the panel spec. A 25 dB(A) enclosure is far cheaper than a 35 dB(A) one.
- Panel construction — STC rating, sheet gauge, and rockwool density (48–100 kg/m³) directly change material cost per m².
- Enclosure type — a factory-built canopy that ships as a kit costs far less than a site-built acoustic room.
- Ventilation & attenuation — acoustic louvers, attenuators and forced ventilation add cost but are non-negotiable for compliance.
- Supply-only vs turnkey — installation, foundations, and post-commissioning noise testing can add 15–30% to a supply-only price.
Canopy vs Acoustic Room: Two Very Different Budgets
The single biggest fork in the price is the enclosure type. A weatherproof acoustic canopy wraps the DG set closely and ships as a bolt-together kit. An acoustic room treats an entire DG hall with wall linings, acoustic doors and ventilation — more capacity, more cost.
Acoustic canopy
- Typical range ₹50,000 – ₹3,00,000
- Factory-built, quick to install
- Best for outdoor / standby DG sets
- Weatherproof, compact footprint
Acoustic room
- Typical range ₹2,00,000 – ₹15,00,000
- Site-built wall & ceiling treatment
- Best for large / indoor DG halls
- Higher insertion loss, walk-in access
Indicative Price by DG Rating
As a rough budgeting guide, canopy prices scale with generator size. Treat these as ball-park supply figures for a CPCB-compliant enclosure — a firm number always needs the exact kVA, site zone and target level.
What Should Be Included — and the Hidden Costs
A price is only comparable if the scope is the same. Before comparing two quotes, confirm each includes:
- Acoustic panels at the specified STC and rockwool density
- Acoustically treated intake and exhaust ventilation (louvers + attenuators)
- Acoustic access door(s) with neoprene gaskets
- Exhaust silencer / residential-grade muffler where required
- Installation, sealing and a post-commissioning noise test report
The cheapest quote is rarely the cheapest enclosure: a unit that fails the CPCB test at commissioning costs far more to rework than one specified correctly the first time.
How KBG Group Prices an Enclosure
KBG Group is an ISO 9001:2015 certified acoustic enclosure manufacturer with 150+ installations across India. We quote against a measured target — your DG rating, the site's zone limit, and the required insertion loss — and deliver turnkey supply, installation and compliance testing, so the number you approve is the number that passes inspection.
Send us the details and we'll size the enclosure and share a firm quotation at no cost.
Frequently Asked Questions
What is the price of a DG-set acoustic enclosure in India?
Canopy-type acoustic enclosures typically range from ₹50,000 to ₹3,00,000, while walk-in acoustic rooms range from ₹2,00,000 to ₹15,00,000+, depending on generator kVA, required insertion loss, panel specification, and whether installation is included.
What determines the cost of an acoustic enclosure?
The main cost drivers are the required insertion loss (25–35 dB(A)), panel construction (STC rating, sheet gauge, rockwool density), enclosure type (canopy vs room), acoustic ventilation, and whether the quote is supply-only or turnkey with installation and noise testing.
Is a canopy or an acoustic room cheaper?
A factory-built acoustic canopy is significantly cheaper and faster to install, suited to outdoor and standby DG sets. An acoustic room costs more but offers higher insertion loss and walk-in access, suited to large or indoor DG halls.
Does the price include CPCB compliance testing?
It should. A complete turnkey quotation from KBG Group includes installation and a post-commissioning noise test confirming the enclosure meets the CPCB limit of 75 dB(A) at 1 metre. Always confirm this is in scope before comparing prices.
How do I get an accurate acoustic enclosure quotation?
Share your DG set kVA, the site zone (industrial/commercial/residential), and the target noise level. KBG Group will size the enclosure to the required insertion loss and provide a firm, itemised quotation at no cost.
