Acoustic Wallcoverings and Panels for Open-Plan Offices

Open-plan office acoustics is one of the most reliable ways for an otherwise excellent interior to fail in occupant satisfaction. The visual language reads as modern, the lighting is well designed, the furniture is specified at premium grade — and the room sounds like a swimming pool changing room. Phone calls bounce. Conversations carry across half the floor plate. Concentration becomes a low-grade endurance task. The post-occupancy survey shows acoustic complaint as the single largest dissatisfier, year after year, in study after study.

The acoustic problem in open-plan space is a hard-surface problem. Concrete soffits, glazed elevations, painted drywall, and tile or polished-concrete floors are all acoustically reflective. Sound energy enters the room and bounces multiple times before being absorbed. Reverberation time extends, and the room becomes acoustically uncomfortable even when sound levels are not particularly high.

At Goodrich, acoustic wallcoverings and panels are one of the most-specified categories of our commercial portfolio for exactly this reason. This article sets out how acoustic wall and ceiling specification works in commercial open-plan space, where it earns its place in the project budget, and the selection criteria we use across our co-working, corporate office, and education work.

The Physics, Briefly

Sound energy in an enclosed space dissipates through three mechanisms: absorption (energy converted to heat in the absorbing material), transmission (energy passes through the surface to an adjacent space), and dissipation through openings. For interior acoustic comfort, absorption is the primary lever. The metric is the noise reduction coefficient (NRC), measured 0.0 (perfect reflection) to 1.0 (perfect absorption), averaged across speech frequencies.

For comfortable open-plan office acoustics, the room’s average surface NRC needs to be in the 0.4 to 0.6 range. Painted drywall has an NRC of around 0.05; tile and polished concrete are similar. Acoustic ceiling tiles can deliver 0.7 to 0.9. Acoustic wallcoverings and panels typically deliver 0.5 to 0.95 depending on construction, and are the primary lever when the ceiling is exposed concrete (as it is in most modern industrial-aesthetic open-plan office designs).

The Categories of Acoustic Wall Treatment

Acoustic wallcoverings

Continuous textile or fibre-based wallcovering products engineered for sound absorption. Applied like standard wallcovering but constructed from porous materials with NRC values typically 0.3 to 0.6 depending on backing and substrate. Suitable for full-wall coverage where the design language calls for a continuous decorative surface that also performs acoustically. Pattern and colour range comparable to standard decorative wallcovering.

Acoustic wall panels (Zintra and equivalent)

Modular panels of compressed PET fibre, mineral fibre, or specialist acoustic foam, faced or wrapped in decorative fabric, with NRC values typically 0.65 to 0.95. Applied as discrete panels mounted to walls or ceilings — sometimes geometric, sometimes continuous-pattern, sometimes brand-driven custom shapes. Goodrich specifies the Zintra range across co-working, corporate, and education work for the combination of acoustic performance, design freedom, and ease of installation.

Acoustic ceiling treatments

Ceiling-mounted acoustic panels, suspended baffles, or full acoustic ceiling tile systems. In open-plan offices with exposed services and concrete soffits — the contemporary default — acoustic ceiling treatment is delivered as suspended panels and baffles rather than tile systems, preserving the industrial aesthetic while adding the absorption.

Combined wall-and-ceiling specifications

Most successful open-plan acoustic specifications combine wall and ceiling treatment. The reason is geometric: sound bounces between walls and ceilings repeatedly, and absorbing only one plane leaves the other to continue reflecting. Coordinated specifications across walls, ceilings, and (where possible) furniture upholstery deliver the absorption budget the room needs.

Where Acoustic Treatment Earns Its Place

Co-working and flexible workspace

Co-working operators run open-plan space at higher density than traditional corporate offices. Member-experience scores are directly affected by acoustic comfort; member churn correlates with acoustic dissatisfaction in industry survey data. Acoustic specification is a member-retention investment, not a fit-out aesthetic decision.

Goodrich has supplied acoustic wallcoverings, panels, and complementary specifications across multiple co-working and flexible workspace projects in Singapore. The brief is consistent: hard-surface industrial aesthetic at the visual level, acoustic comfort at the experience level. Reconciling the two requires specification of acoustic absorption into the wall and ceiling planes that read as deliberate design elements rather than as acoustic compromise.

Corporate open-plan offices

Corporate office tenants are increasingly briefing for “library quiet” or “concentration zone” acoustic experience in dedicated areas of an otherwise open-plan floor plate. Acoustic wallcoverings and panels deliver the brief without requiring full enclosure of the zone. Combined with acoustic ceiling clouds and acoustic soft furnishing in the adjacent areas, the specification creates differentiated acoustic experiences within a single open-plan floor.

Meeting rooms and huddle spaces

Glass-walled meeting rooms have become ubiquitous and they have a specific acoustic problem: speech bounces hard inside the glass-and-drywall envelope. Acoustic wallcoverings on the drywall surfaces, combined with ceiling panel treatment, transform the in-room acoustic experience without compromising the daylight and visual transparency the glass walls deliver.

Education and lecture spaces

Classrooms, lecture theatres, and library reading rooms all benefit from acoustic wall treatment. The brief differs from office: speech intelligibility from instructor to learner, with controlled reverberation that supports both lecture-format and discussion-format learning, drives the specification. Education projects are a major proportion of our acoustic specification work — we have supplied acoustic wallcoverings, fabric wall panels, and acoustic ceiling treatment to international schools, polytechnics, and universities across Singapore and the region.

Hospitality public areas

Hotel lobbies, hospitality F&B spaces, and conference centre public areas all have acoustic comfort briefs. Hospitality acoustic specification typically uses acoustic wallcovering more than panel because the visual brief calls for continuous decorative surfaces; panel-led specifications appear in more contemporary hospitality where the panel itself is a design element.

Healthcare consultation and waiting

Healthcare interiors require acoustic privacy (consultation rooms, treatment rooms) and acoustic comfort (waiting areas, corridors). The specification combines acoustic wall and ceiling treatment with attention to sound transmission between rooms — the latter typically managed at the partition level rather than the surface treatment level.

The Specification Framework

1. Identify the target reverberation time

For open-plan office, the target is typically 0.5 to 0.8 seconds at mid-frequencies. For lecture and education space, 0.6 to 1.0 seconds. For hospitality lobbies, 0.8 to 1.2 seconds (some reverberation reads as appropriately atmospheric in hospitality). For library and concentration spaces, below 0.5 seconds. The target drives the absorption budget.

2. Calculate the absorption budget

For a given room volume and surface area, the reverberation target translates to a total absorption requirement (sabines). The current room (with all hard surfaces) provides a baseline; the gap is what acoustic specification needs to close. Acoustic engineers typically run this calculation; for projects without acoustic consultants, conservative rules of thumb work for most office and education spaces.

3. Distribute the absorption across surfaces

The absorption budget is distributed across walls, ceilings, and furniture. The right distribution depends on the room geometry, the surfaces available for treatment, and the design language. Successful specifications generally treat both wall and ceiling planes; treating only one rarely delivers the calculated reverberation reduction.

4. Match the design language

Acoustic wallcoverings and panels are available in a wide range of patterns, colours, and panel geometries. The specification should read as a deliberate design element — not as a remedial intervention. The Zintra range, for example, offers panel geometries from straight edge through angled and contoured shapes; the panels can be installed as continuous walls, dispersed feature elements, or geometric ceiling clouds.

5. Coordinate with mechanical, lighting, and services

Acoustic ceiling specifications interact with lighting layouts, sprinkler positions, HVAC outlets, and access requirements. The acoustic specification needs to be coordinated with the M&E coordination drawings — ideally early in design rather than late.

Common Specification Mistakes

• Specifying only walls or only ceilings. Single-plane specifications consistently underperform calculated reverberation reduction. Both planes need treatment.
• Confusing acoustic absorption with sound transmission. Absorption controls reverberation within a room; transmission controls sound passing between rooms. The specifications are different and the products are different. Absorption material on a partition does not stop speech transmission to the adjacent meeting room.
• Choosing acoustic products on look alone. The decorative range across acoustic products is wide. NRC performance varies. Specifying for visual fit without checking acoustic performance produces a beautifully appointed room that still does not perform.
• Treating acoustic specification as value-engineering optional. Acoustic comfort is consistently the largest occupant satisfaction dissatisfier in open-plan office surveys. Removing acoustic specification at value-engineering stage is the mistake we see most often regretted post-occupancy.

Acoustic in the Larger Specification

The strongest acoustic specifications coordinate with adjacent material decisions. Carpet tile and broadloom flooring contributes absorption (NRC 0.20 to 0.45). Soft furnishing fabric, particularly acoustic-grade upholstery and fabric-wrapped panels, contributes absorption. Curtains and drapery contribute absorption. The total acoustic budget across all soft surfaces in a room is what delivers the comfort experience — acoustic wallcovering and panels are typically the largest single contributor but rarely the only contributor.

Coordinating the specification across carpet, fabric, and acoustic wall treatment delivers the integrated acoustic experience that single-element specifications cannot. The Goodrich product range is engineered to support this integrated specification, and our project teams scope acoustic projects across the full surface palette rather than treating wall acoustics as a standalone line item.

How to Specify with Goodrich

The shortest path to a confident acoustic specification is a coordinated brief: room dimensions, surface schedule, acoustic target, design language, and project programme. We develop sample boards spanning acoustic wallcoverings, Zintra panel options, complementary fabric upholstery, and carpet specifications, work through the absorption budget with the design team, and quote on a supply-and-install basis. For multi-phase rollouts across co-working operators, corporate occupier portfolios, or education campuses, the same scoping process scales — coordinated specifications across phases ensure visual consistency and operational simplicity.
