Acoustic Wall Panels — Buy Sound Absorbing Wall Panels in India

Every room has a noise problem. Open-plan offices buzz with conversation. Conference rooms echo on video calls. School classrooms muddy every word the teacher says. Restaurants are too loud for comfortable dining. Recording studios produce coloured, reverberant recordings that frustrate engineers. Auditoriums lose clarity at the back of the hall.

The solution in every case starts with the same product: acoustic wall panels — engineered surfaces that absorb sound energy, control reverberation, reduce echo, and transform how a space sounds and feels.

Ecotone Acoustic Limited manufactures the full range of acoustic wall panels available in India — grooved wooden slats, perforated wooden panels, wood wool fibre boards, fabric-wrapped panels, CNC PET felt panels, micro-perforated panels, metal acoustic panels, and composite acoustic panels — all under a single roof at our Greater Noida facility. Every panel is independently NRC-tested, fire-rated, and available with complete technical documentation for green building certification, architectural specification, and contractor BOQs.

This page covers every product in our acoustic wall panel range, what each one does, where each one belongs, and how to specify, buy, and install the right solution for your project.

How Acoustic Wall Panels Work

Sound is energy. When a speaker speaks, machinery operates, or music plays, the sound source creates pressure waves that travel outward in all directions. When those waves strike a hard surface — concrete, glass, plasterboard, marble — the vast majority of the energy reflects back into the room. Multiple reflections combine, overlap, and persist, creating the reverberation, echo, and noise buildup that makes spaces acoustically uncomfortable.

Acoustic wall panels interrupt this cycle. They are constructed from materials — fibrous mineral wool, open-cell polyester fibre, natural wood fibre, or resonant panel systems — that do not reflect sound. Instead, they convert the kinetic energy of the sound wave into a negligible amount of heat through friction between air molecules and the panel’s internal structure. The reflected energy returning to the room is dramatically reduced. Reverberation time shortens. Speech clarity improves. Background noise levels fall. The space becomes easier to work, learn, and communicate in.

The key performance metric is NRC — Noise Reduction Coefficient — a number between 0.0 and 1.0 that represents the average proportion of sound absorbed at four standard frequencies (250 Hz, 500 Hz, 1000 Hz, and 2000 Hz). A panel rated NRC 0.90 absorbs 90% of the sound striking it. An unpainted concrete wall has NRC 0.02 — it absorbs almost nothing. Ecotone Acoustic Limited’s acoustic wall panels achieve NRC values from 0.65 to 1.0 depending on product type, thickness, and installation configuration.

Our Acoustic Wall Panel Range — 8 Products, Every Application Covered

1. EchoStop™ Grooved Wooden Slat Panels

2. EchoStop™ Micro Perforated Wooden Panels

For frequency-tuned acoustic control in auditoriums, cinemas, and studios.

Perforated wooden acoustic panels — also called wooden sound slats or acoustic wood panels — use a precision-drilled perforation pattern in the face of a high-density pre-laminated MDF board. The Helmholtz resonator principle governs their performance: hole diameter, spacing, panel depth, and backing depth together determine which frequency bands are absorbed most effectively. This tunability makes perforated panels the preferred specification for acoustic consultants working on spaces with defined frequency targets.

Ecotone Acoustic Limited’s M and T perforation patterns are engineered to deliver effective absorption across low, medium, and high frequency ranges — among the broadest-spectrum wooden panel systems available in India.

Technical specifications:

• Core: High-density pre-laminated MDF / HDF, IS-14587:1998
• Hole diameters: 6 mm / 8 mm / 10 mm standard; ultra micro-perforated at 0.5–0.8 mm diameter
• Panel thickness: 16 mm (wall); 6 mm / 12 mm (ceiling applications)
• Panel sizes: 600×2440 mm (wall); 600×600 mm / 600×1200 mm / 600×2440 mm (ceiling)
• Backing: Black acoustic fleece; cavity infillable with polyester fibre or rockwool
• Installation: GI ‘Z’ clamp and ‘U’ channel grid system; dowel joints between panels
• NRC: 0.75 to 0.95 depending on perforation pattern and cavity specification
• Fire rating: IS/ASTM rated
• Finishes: Pre-laminated in matt or melamine gloss, 50+ options; or mica laminated

Indicative price: ₹600–₹1,200 per sq ft (supply + installation)

4. Fabric-Wrapped Acoustic Panels (EchoStop™ Echo Stop)

Maximum NRC. Unlimited colour. The professional standard for offices, boardrooms, and studios.

Fabric-Wrapped Acoustic Panels deliver the highest NRC values available from any wall-mounted acoustic panel format. A high-density glass wool or rockwool core — a minimum of 48 kg/m³ for glass wool — is wrapped in acoustically transparent fabric stretched over a rigid timber or aluminium frame. The fabric allows sound to pass through freely; the absorptive core converts that sound into heat. The result: NRC 0.95 at 25 mm, up to NRC 1.0 at 50 mm or above, tested to ASTM E1050 / ISO 10534-2.

The design versatility is equally exceptional. With 100+ fabric colours, textures, and patterns, plus full-colour graphic image printing, fabric-wrapped panels can be specified to match any corporate brand palette, biophilic design scheme, or hospitality aesthetic.

Technical specifications:

• Core: High-density glass wool (min. 48 kg/m³) or rockwool; 25 mm / 50 mm / 75 mm thickness
• Standard size: 1200×600 mm; custom sizes and shapes available (rectangular, square, circular, hexagonal)

5. Groovphonic™ Composite Acoustic Panels

Acoustic performance meets impact resistance — for auditoriums, school halls, and commercial spaces.

Groovphonic™ Composite Acoustic Panels bond a grooved and perforated timber face with a polyester fibre acoustic pad core using rubber-based adhesive, creating a single integrated panel that is more structurally robust than standard grooved slat panels. All joints use dowel connections; edges are tapered-cut to produce a V-joint finish. The construction delivers both acoustic absorption and the structural durability required for walls that will experience physical contact.

Technical specifications:

• Total panel thickness: 25 mm
• Groove size: 3.2 mm at 28/62 mm centres (or per architect/acoustic design)
• Core: Polyester fibre acoustic pad, rubber-bonded to perforated wooden face

6. EchoStop™ CNC PET Felt Acoustic Panels

Eco-friendly. Any shape. Any colour. The designer’s acoustic panel.

CNC PET Felt Acoustic Panels are manufactured from post-consumer recycled PET fibres — reclaimed from plastic bottles — compressed into rigid, self-supporting panels. They are Ecotone Acoustic Limited’s most visually versatile acoustic wall panel: available in 30+ solid colours, and precision CNC or laser-cut into any geometric, organic, or custom shape, they function simultaneously as acoustic treatment and decorative wall art.

Each standard 9 mm PET panel uses approximately 60–90 recycled 500 ml plastic bottles per square metre, making them the most sustainable panel option in the range with genuine life-cycle environmental credentials.

Technical specifications:

• Material: Post-consumer recycled PET polyester fibre
• Available thicknesses: 9 mm, 12 mm, 15 mm
• NRC: 0.65–0.85 at standard thickness; 0.80–0.95 at 25 mm+ with air gap

• Low-VOC, formaldehyde-free, humidity-resistant, fully recyclable
• Lightweight: suitable for wall and ceiling installation without heavy fixing requirements

Indicative price: ₹200–₹500 per sq ft (supply + installation; standard shapes)

Best for: Co-working spaces, creative agencies, schools, children’s learning environments, cafes, restaurants, retail environments, and any project where acoustic treatment must also function as a colour-coordinated design feature or brand expression.

7. Micro-Perforated Acoustic Panels

Near-invisible perforation. Seamless aesthetics. Premium acoustic performance.

Micro-perforated acoustic panels take the principle of the perforated panel to its visual extreme: perforation holes of 0.5–0.8 mm diameter — approximately 140,000 holes per square metre — are so fine that they are virtually invisible at normal viewing distances. The surface reads as a clean, uninterrupted flat panel. The acoustic performance is the result of Helmholtz resonance principles acting at micro-scale, with the cavity behind the panel contributing significantly to the frequency response.

Technical specifications:

• Core: 16 mm MDF / ply / fire-rated ply / WPC board
• Perforation: 0.6–0.8 mm diameter holes at 02 mm c/c; approximately 140,000 holes/m²
• Surface: 0.5 mm mica laminate in desired shade (50+ colours available)
• Backing: Black acoustic fleece
• Installation: GI ‘Z’ clamp and ‘U’ channel grid (50×32 mm); cavity filled with rockwool 60 kg/m³ (IS 8183)
• NRC: Up to 0.85 with full cavity specification
• Sizes: 600×600 mm / 600×1200 mm / 600×2420 mm
• Dowel joints between all panels — no sagging

Best for: Museums, art galleries, premium residential interiors, luxury hotel corridors, executive office suites, and any space where sound control is required but visible perforation is aesthetically unacceptable.

8. Metal Perforated Acoustic Panels (AcoMetal™)

Industrial-grade acoustic absorption. Cleanable, moisture-resistant, built to last.

Metal Perforated Acoustic Panels provide acoustic absorption with the durability, cleanability, and moisture resistance that fabric or wood-based panels cannot deliver in demanding environments. Ecotone Acoustic Limited’s AcoMetal™ panels use a modular wall or ceiling unit consisting of a metal or aluminium frame surrounding a perforated metal skin — 22-gauge perforated galvanised steel, typically — with an encapsulated acoustic fiberglass fill sealed in black heat-sealed polywrap. Sound enters through the perforations and is absorbed by the fiberglass fill, with a portion converted from sound energy to heat.

Technical specifications:

• Face: 22-gauge perforated galvanised steel or aluminium; powder-coated in RAL colours
• Core: Acoustic fiberglass fill, encapsulated in black heat-sealed polywrap
• Backing: Flush or stand-off mounting options
• NRC: 0.55–0.85 depending on perforation density and panel configuration
• Fire rating: Class A (inherently non-combustible metal face)
• Humidity resistance: Fully moisture-resistant — suitable for swimming pools, wet areas, industrial spaces
• Customisation: Perforation patterns, panel sizes, powder coat colours, and mounting options

Best for: Gymnasiums and sports halls, swimming pool enclosures, pump rooms, industrial fabrication facilities, commercial kitchens and canteens, healthcare facilities, transit hubs, and any space requiring an acoustic surface that can be washed, hosed down, or exposed to moisture and temperature variation.

How Much Wall Coverage Do You Need?

Coverage area is the most common acoustic wall panel specification mistake in India. Undertreating the wall area — installing too few panels, or placing them only as feature elements — leaves the acoustic problem partially unsolved even after a complete installation.

Use these coverage benchmarks as a starting point, always confirmed by an acoustic model for your specific room dimensions and target RT60:

Corporate offices (open-plan): 20–30% of total wall area with NRC ≥ 0.75, combined with acoustic ceiling treatment (baffles or clouds), achieves the RT60 target of 0.4–0.6 seconds specified for office speech environments.

Conference rooms and boardrooms: 25–35% of wall area with NRC ≥ 0.85 at primary reflection surfaces (rear wall, side walls adjacent to the meeting table). Fabric-wrapped or WFF wood wool panels are the standard specification for this application.

School classrooms: 30–40% of wall area, NRC ≥ 0.75, combined with acoustic ceiling tiles or panels. Wood wool (VOC-free, Class A fire rated) is the recommended specification for Indian school environments.

Auditoriums and performing arts venues: 35–50% of wall area depending on room volume and target RT60. Perforated wooden panels or Groovphonic™ composite panels on side and rear walls, with fabric-wrapped panels at first-reflection points.

Recording studios and broadcast rooms: 40–60% of wall area, NRC ≥ 0.90. Fabric-wrapped panels (50–75 mm core) at all primary surfaces; grooved wooden slats or composite panels where diffusion is needed alongside absorption.

Restaurants and hospitality spaces: 20–30% of wall area, NRC ≥ 0.75. Grooved wooden slat panels are the dominant specification for hospitality — they deliver real absorption while reading as premium timber cladding, not as acoustic treatment.

Industrial facilities and canteens: Wall panels are secondary to ceiling treatment in industrial environments. Where wall panels are specified — alongside acoustic hanging baffles and ceiling clouds — WFF wood wool or metal perforated panels are appropriate for their durability and broadband performance.

Applications: Where Acoustic Wall Panels Make the Biggest Difference

Corporate Offices and Open-Plan Workspaces

Open-plan offices are among India’s most acoustically challenging commercial environments. Hard ceilings, glass partitions, polished floors, and high occupancy create reverberation times of 1.0–1.5 seconds or more in untreated spaces — far above the 0.4–0.6 second target for speech-focused office environments. EchoStop™ grooved wooden slat panels on perimeter walls and feature walls, combined with acoustic ceiling clouds or hanging baffles overhead, is the most effective acoustic treatment combination for open-plan Indian offices — as demonstrated in Ecotone Acoustic Limited’s 12,000 sq ft Gurugram office project, where this combination achieved an 8 dB ambient noise reduction measured post-installation.

For conference rooms and boardrooms within the same floor plate, fabric-wrapped panels at NRC 0.95–1.0 on the rear and side walls — combined with an acoustic ceiling cloud above the meeting table — achieve the 0.4–0.6 second RT60 target that WELL Building Standard v2 and LEED India require for enclosed meeting spaces.

Auditoriums, Cinemas, and Performing Arts Venues

Ecotone Acoustic Limited has delivered acoustic wall treatments for some of India’s most acoustically demanding performance spaces — including the BAPS Swaminarayan Mandir auditorium in Ahmedabad and a 450-seat school auditorium achieving optimal RT60 as per IS:4954 — and across six multiplex cinema halls achieving NRC 0.90+ within each auditorium.

For auditoriums, the specification typically combines EchoStop™ perforated wooden panels or Groovphonic™ composite panels on side walls (delivering absorption with some diffusion — critical for natural sound character), with fabric-wrapped panels at first-reflection points where maximum absorption is needed, and WFF wood wool on the rear wall for broadband bass and mid-frequency control.

Hotels, Restaurants, and Hospitality Spaces

EchoStop™ grooved wooden slat panels — available in natural timber finishes including teak, mahogany, maple, walnut, and beech — align naturally with premium hospitality interior design. They deliver real acoustic performance (NRC 0.75–1.0 with appropriate backing) while reading as a design feature rather than an acoustic intervention. Ecotone Acoustic Limited has supplied acoustic wall panels for Hyatt Regency Bhikaji Cama Place, Crowne Plaza Gurgaon, and multiple five-star hospitality projects across India.

For restaurants specifically, treating 20–25% of wall area with EchoStop™ grooved slats — combined with acoustic treatment at ceiling level — reduces the ambient noise cycle that forces diners to raise their voices and progressively increases the perceived noise level for everyone in the space.

Educational Institutions

Poor classroom acoustics measurably impair learning outcomes — particularly for children with hearing difficulties, English as a second language, or attention challenges. WFF wood wool panels are the recommended specification for Indian school environments: they are VOC-free, meet ASTM Class A fire rating, achieve NRC 0.90 tested to international standards, and withstand the robust daily use of school environments. For school assembly halls, gymnasiums, and libraries, Ecotone Acoustic Limited specifies WFF panels on upper walls combined with acoustic hanging baffles in high-volume spaces.

Healthcare Facilities

Hospital environments require acoustic wall panels that are infection-control compliant — wipeable, non-porous, and resistant to cleaning agents. Metal perforated panels (AcoMetal™) meet these requirements in clinical areas, operating theatres, and wet zones. Fabric-wrapped panels are appropriate for administrative zones, waiting areas, and staff offices where clinical hygiene standards are lower. Ecotone Acoustic Limited provides NBC 2016-compliant acoustic specifications for all healthcare applications.

Recording Studios and Broadcast Facilities

Recording studios require the highest acoustic precision available. Fabric-wrapped panels at NRC 1.0 (75 mm glass wool core) are specified at all primary reflection surfaces; micro-perforated panels provide a flat, cleanable surface where a hard finish is preferred for specific monitoring positions; EchoStop™ grooved wooden slat panels add visual character and diffusion to the live room. Ecotone Acoustic Limited designs complete studio acoustic environments integrating all three panel types with bass trap treatment and mechanical isolation.

Installation: What the Process Looks Like

All Ecotone Acoustic Limited acoustic wall panels are installed by our own professional installation teams — not subcontracted — ensuring that the acoustic performance of the specified panel is realised in the installed system, not just on the data sheet.

Standard installation sequence for grooved slat and perforated panels:

1. Surface preparation: Substrate wall cleaned, plumbed, and verified flat. Electrical outlets and service penetrations marked and accommodated in layout plan.
2. GI grid installation: ‘U’ channel grid (50×32 mm) fixed to wall at 600×900 mm grid spacing using stainless steel screws.
3. Cavity infill: Rockwool or polyester fibre placed between grid members at specified density. This step is non-optional — the acoustic consultant’s cavity depth and infill density specification is a functional part of the acoustic system.
4. Acoustic fleece: Black acoustic fleece applied across grid face or bonded to panel reverse before installation.
5. Panel installation: Panels mounted on GI ‘Z’ clamps; dowel joints between adjacent panels ensure flat, gap-free surface with no sagging.
6. Finishing: Edge panels cut to size; V-joint edge detail applied where specified; electrical faceplates and service penetrations completed.

Critical specification warning: Grooved and perforated wooden panels installed without acoustic backing and cavity infill deliver NRC 0.10–0.20 — comparable to a plain timber wall. The backing is a functional acoustic component, not a cost line that can be value-engineered away. Ecotone Acoustic Limited’s installation methodology includes verification of backing installation before panel fixing begins — a quality control step that contractor-only installation frequently skips.

Frequently Asked Questions

What is the difference between acoustic wall panels and soundproofing?
Acoustic wall panels reduce reverberation, echo, and noise buildup within a room by absorbing sound energy. They do not prevent sound from passing between rooms — that requires soundproofing (STC-rated walls, partitions, and doors). Most spaces need both: acoustic treatment inside and isolation at the boundary. Ecotone Acoustic Limited supplies both — see our soundproof partition range and STC-rated wall systems.

What NRC rating should I specify for a corporate office?
For open-plan offices, NRC ≥ 0.75 for wall panels is the minimum meaningful specification. For conference rooms and boardrooms, NRC ≥ 0.85 is recommended on primary reflection surfaces (rear wall, side walls). Ecotone Acoustic Limited’s acoustic consultants calculate the precise NRC and coverage area required for your specific room volume and RT60 target.

Can acoustic wall panels be used on ceilings as well?
Yes. EchoStop™ grooved wooden slats, perforated panels, fabric-wrapped panels, and WFF wood wool tiles are all available in ceiling configurations — direct-fix to substrate ceiling or suspended in grid systems. For exposed ceiling applications in open-plan spaces, acoustic hanging baffles and PerfoAudile™ acoustic clouds are the preferred ceiling treatment. Combining wall and ceiling acoustic treatment always delivers better results than treating either surface alone.

Are Ecotone Acoustic Limited’s panels fire rated for auditoriums and public buildings?
Yes. All commercial panels in our range carry appropriate fire safety ratings: ASTM D-876 Class A for WFF and fabric-wrapped panels; IS/ASTM fire classification for grooved and perforated wooden panels (chemically fire-retardant treated); inherently non-combustible AcoMetal™ metal panels. Fire certification documents are provided with every project specification.

Do acoustic wall panels qualify for LEED India or GRIHA certification credits?
Yes. Ecotone Acoustic Limited’s panels contribute to multiple LEED v4.1 and GRIHA credit categories: Indoor Environmental Quality (Acoustic Performance), Materials and Resources (recycled content — certified 35% recycled glass), and Low-Emitting Materials (VOC-free construction). Full documentation — NRC test certificates, recycled content certificates, VOC-free declarations, and fire rating certificates — is provided for green building credit submissions.

How long does an acoustic wall panel installation take?
A single conference room (30–50 sq m of panel area) typically takes 2–3 days. A full open-plan office floor (500–1,000 sq m) takes 2–4 weeks depending on access, ceiling height, and panel layout complexity. Ecotone Acoustic Limited’s installation teams work in sections to minimise disruption to operational spaces.

Can panels be customised with our brand colours or graphics?
Yes. Fabric-wrapped panels are available with full-colour graphic and photographic printing on the fabric face. CNC PET felt panels are available in 30+ colours with unlimited CNC-cut shapes including brand logo cut-outs and custom geometries. EchoStop™ grooved slat panels are available in 50+ pre-laminated finishes. Ecotone Acoustic Limited’s design team works directly with architects and interior designers to match panel specifications to the project’s visual identity.
