Most industrial sites weren't built with sound in mind. They were built for output — for throughput, square footage, machine placement. Noise was just something that came with the territory. That's changing fast. Regulators are tightening permissible exposure limits, residential zoning boards are pushing back on plants near housing, and the old approach of "deal with complaints as they come" doesn't hold up anymore. Architectural acoustics has moved from an afterthought to something facility teams have to plan for upfront.
At SomNandi Industries, we've watched this shift happen across dozens of projects. A plant manager calls because workers can't hear each other over the line noise, or because a new residential block went up next door and now there's a compliance notice on the desk. The fix usually isn't "build a wall." It's something more specific to the space — and increasingly, it has to be something that doesn't waste material or energy getting there.
Here's the thing about noise compliance: it's not just a legal box to check. Good architectural acoustics work actually solves a people problem first. Workers in loud environments get tired faster, lose focus, and tend not to stick around. Hearing damage claims and turnover both cost more than most companies expect. So when we talk about architectural acoustics, we're really talking about two problems at once — meeting the regulation, and keeping people functional on the floor.
The harder part is doing this sustainably. Old-school soundproofing leaned on dense, heavy materials — thick mineral wool blankets, solid masonry, lead-lined panels in extreme cases. Effective, sure, but resource-intensive to produce and a nightmare to retrofit into an existing building. Facilities today need something lighter: modular where possible, recyclable where it matters, and not wasteful in how it's made or installed.
Engineering Quiet Without Compromise
SomNandi Industries treats every project as a trade-off between performance and footprint — not performance versus footprint, but finding where they overlap. Below is how each of our core products fits into that.
Work Pod
The Work Pod is a self-contained booth, basically — built for offices and plant control rooms where someone needs quiet without tearing down a wall. Sound-absorbing panels, insulated glass, sealed doors that keep noise from leaking either direction. Ventilation's built in so it doesn't feel stuffy after twenty minutes, and there's lighting and power points for whatever equipment people bring in. We make these in 2-seater, 4-seater, and 6-seater sizes. Installation is fast, and because the pod can be moved later, it skips the waste that comes with building (and eventually demolishing) permanent partitions. For a plant floor that just needs one quiet corner, this is usually the cleanest answer.
Sliding Partition
Sliding Partitions solve a different problem: space that needs to change shape depending on the day. These are top-hung systems — panels glide on an overhead track, and a lot of our installs skip floor tracks altogether so the finish stays seamless. One person can open or close the whole thing. The cores are solid, joints are sealed, and the acoustic separation holds up well enough to keep a noisy machine bay from bleeding into an office space next door. Finishes come in wood, laminate, glass, or fabric. What makes this sustainable in practice is simple: you're not rebuilding walls every time the layout needs to change. You're just sliding them.
Acoustic Hanging Baffles
Tall, open spaces — warehouses, big factory floors — have a reverberation problem that ceiling tiles alone don't fix. Acoustic Hanging Baffles are vertical panels suspended from the ceiling, absorbing sound from both faces instead of just one. That dual exposure catches a lot of the diagonal and horizontal echo that wall panels miss entirely. The cores are rigid, finishes resist dust and moisture, and because nothing structural needs to change to install them, baffles end up being one of the lowest-waste retrofit options we offer. Workers hear instructions better, alarms cut through, and none of that required touching the building itself.
Acoustic Clouds
Acoustic Clouds are the horizontal cousin to baffles — suspended ceiling panels, but absorbing from above and below at once. NRC ratings run 0.70 to 1.00 depending on spec, and they come in custom shapes (rectangles, hexagons, actual cloud forms) up to 1200 x 2400 mm. Materials are lightweight — PET, mineral wool, acoustic foam — and we offer recycled PET and low-VOC options for teams that need that on record. These work especially well over packaging lines, assembly floors, or admin areas inside a larger industrial site, where a full ceiling treatment would be overkill.
Auditorium Acoustic
Bigger industrial campuses usually have a training hall or briefing room somewhere, and those spaces need their own acoustic plan. We've been doing this for over 25 years — fabric-wrapped panels, perforated wood, ceiling clouds and baffles for reverberation, diffusers to spread sound evenly, and stage-specific treatment where presentations or live audio matter. HVAC and fan noise gets handled through vibration isolation and louvers. Before anything's installed, we model the space using EASE, CAD, or BIM so there are no surprises once the room is built out. We've completed over 100 of these projects across India, and we hold ISO 9001 and ISO 14001 certification — which matters when a client's compliance team asks for paperwork.
Sustainability as a Design Principle, Not an Afterthought
What connects all five of these — Work Pod, Sliding Partition, Acoustic Hanging Baffle, Acoustic Cloud, Auditorium Acoustics — is that none of them treat sustainability and compliance as competing goals. They're built to last, which cuts down on replacement waste, and most of them install without touching the building's existing structure.
Regulations aren't getting looser. They're getting stricter, and the facilities that handle that well are the ones that planned for sound early instead of scrambling after a complaint letter shows up. We keep investing in materials and methods because the bar keeps moving, and we'd rather our clients stay ahead of it than catch up to it.
If you're planning a new build, or just looking at an existing site that's gotten too loud, the cheapest fix is almost always the earliest one. Bring architectural acoustics into the design conversation before construction starts, not after. It saves money down the line too — materials and layouts chosen properly the first time don't need constant patching. SomNandi works alongside industrial teams from that first site visit through final commissioning, and we'd rather be involved early than called in for a rescue.
