What Acoustic Panels Actually Do
Acoustic panels absorb sound energy that would otherwise reflect off hard surfaces, reducing echo (reverberation) and overall noise buildup in a room. They don't block sound from entering or leaving a room (that's soundproofing, a different problem) — they improve the sound quality within the room.
Types of Acoustic Panels
- Fabric-wrapped acoustic panels: The most common choice for offices — foam or mineral wool core wrapped in fabric, available in many colours to match interior branding
- PET felt panels: Made from recycled polyester felt, often used for a more textured, design-forward look in modern offices and studios
- Perforated wood/timber acoustic panels: Combine acoustic absorption with a premium, warm aesthetic — popular in corporate boardrooms and reception areas
- Foam acoustic panels (studio-grade): Higher absorption for recording studios and auditoriums where sound accuracy matters more than aesthetics
- Baffles and ceiling clouds: Suspended panels used where wall space is limited or ceiling treatment is more effective (common in open-plan offices)
Where Each Type Makes Sense
| Space | Recommended Panel Type |
|---|---|
| Open-plan office | Ceiling baffles/clouds + fabric wall panels near noisy zones |
| Meeting/conference rooms | Fabric-wrapped or perforated wood panels for speech clarity |
| Recording studios | Foam acoustic panels + bass traps in corners |
| Auditoriums | Fabric-wrapped panels combined with diffusers for even sound distribution |
| Reception/lobby | Perforated wood panels for acoustic control without sacrificing design |
Cost in Bangalore
- Basic fabric-wrapped panels: ₹250–450 per sq. ft, supplied and installed
- PET felt panels: ₹350–600 per sq. ft
- Perforated wood panels: ₹500–900 per sq. ft, given the premium material
- Studio-grade foam treatment: ₹150–350 per sq. ft (foam is cheaper per sq. ft than fabric-wrapped, but studios often need more coverage)
A typical mid-sized meeting room (say, 300 sq. ft of wall treatment) runs roughly ₹75,000–1,35,000 depending on panel type and coverage.
How Much Coverage Do You Actually Need?
This is where a lot of businesses either overspend or under-treat. As a rough guide:
- Light echo/noise issues: 15–25% wall coverage, focused on the surfaces directly opposite hard, reflective walls
- Moderate issues (open-plan offices, meeting rooms with glass walls): 25–40% coverage across walls and/or ceiling
- Studios and auditoriums: Often need 40–60%+ coverage plus corner bass trapping for accurate sound
A proper acoustic assessment (measuring the room and identifying reflection points) gives a far more accurate answer than a blanket percentage — this should be part of any vendor's process before quoting.
Placement Matters More Than Quantity
Panels placed at "first reflection points" (where sound first bounces before reaching your ears) are far more effective than the same panels spread thinly and randomly across a wall. A good acoustic panel installer maps these points before recommending placement, rather than just filling wall space.
