Meet the studio, understand our process and discover how we move from first conversation to finished space.
Make the Room Sound as Considered as It Looks
A room can look beautifully finished and still be exhausting to use. Glass, marble, porcelain, concrete and high ceilings can turn normal conversation into a wash of reflections; a meeting room can look private while speech travels straight through the partition; a home office can make every video call sound hollow. Bella integrates acoustics into the interior so sound control becomes part of the ceiling, wall, furniture, curtain and layout design instead of an obvious technical add-on.
We develop acoustic interior strategies for homes, offices, meeting rooms, restaurants, hospitality spaces, studios and specialist rooms. Depending on the problem, the solution may focus on reverberation and echo, speech privacy, airborne sound isolation, impact noise, mechanical / HVAC noise or a combination. Our role is to connect the acoustic target to the interior layout, finishes and visual language, while specialist acoustic measurement, engineering and statutory certification are coordinated where the project requires them.
First Identify Which Acoustic Problem You Actually Have
The most expensive acoustic mistake is buying panels before defining the complaint. We start by separating what happens inside the room from what travels into or out of it.
This is primarily a room-acoustics problem. We look at reverberation, hard reflective surfaces, ceiling volume and where people speak. High-absorption ceilings, wall panels, baffles, curtains, rugs and upholstered elements can reduce reflected sound without rebuilding the room.
This is a sound-isolation and speech-privacy problem, not simply an absorption problem. We review the full partition, glass, door seals, ceiling void, penetrations and flanking paths. Adding felt panels inside the meeting room may improve clarity but will not automatically stop speech passing through the enclosure.
Open-plan acoustics depend on more than reverberation. Workstation layout, ceiling absorption, screens, distance between teams, speech intelligibility and background / masking sound all affect distraction. We zone collaborative and focus activity rather than expecting one product to solve the whole floor.
We review room orientation, listening / microphone position, early reflections, low-frequency behaviour and the balance between absorption and diffusion. Studio-style rules of thumb can be useful starting points, but measurement and listening should refine the final treatment.
Hospitality spaces often combine hard floors, glass, stone, timber and many simultaneous voices. We use ceiling and wall absorption, upholstered seating, curtains and zoning to control buildup while preserving the lively atmosphere—the goal is not to make the dining room acoustically dead.
Acoustic finishes cannot correct every mechanical source. Diffuser velocity, duct noise, fan vibration, equipment isolation and transfer paths may need MEP / acoustic engineering. We coordinate the interior ceiling and enclosure so the technical solution does not conflict with lighting, access or design intent.
Three Acoustic Layers
A balanced acoustic interior usually needs decisions at more than one layer.
Absorption and diffusion manage what happens after sound is produced inside the room. This is where ceilings, baffles, wall panels, soft finishes and furniture can reduce excessive reverberation and improve clarity.
Walls, doors, glazing, floors, ceilings and penetrations determine how much airborne or impact sound crosses between spaces. Performance depends on the complete assembly and sealing, not one visible finish.
HVAC, equipment, AV and deliberate sound masking can either support or undermine acoustic comfort. We coordinate these systems with the interior so low background noise does not become a hum, hiss or privacy problem.
Different Rooms Need Different Acoustic Priorities
We set the target around the activity, room volume, occupancy and level of privacy required.
Hard floors, glazing and minimalist furniture can make residential rooms unexpectedly reflective. We use visually integrated slats, curtains, rugs, upholstered furniture, discreet panels and layout changes to improve comfort without turning the home into a recording studio.
Open offices need control of speech propagation as well as reverberation. Absorptive ceilings, baffles, screens, pods and intelligent team zoning are combined so collaboration can happen without every conversation travelling across the floor.
Meeting rooms need short, controlled reverberation for clear face-to-face and video communication while the enclosure protects confidential speech. Glass, doors, partitions, ceiling voids and AV all have to be considered together.
Recording and listening rooms need more targeted control of early reflections and low-frequency modes. Broadband absorbers, corner treatment, diffusion, ceiling clouds and speaker / listener positioning are developed around the actual room rather than installed as a decorative grid.
What Acoustic Interior Design Can Include
Bella can develop the interior acoustic strategy and coordinate specialist recommendations. Formal acoustic modeling, laboratory / field testing and engineered sound-isolation design are provided by the relevant acoustic or technical consultant where required.
Define the complaint before selecting a material.
Use distance and adjacency before adding products.
Control lateral reflections while keeping the room visually intentional.
Use the largest available surface without consuming floor area.
Reduce sound transfer where privacy matters.
Use everyday interior elements as part of the acoustic strategy.
Acoustic absorption is not the same as soundproofing. Panels, rugs and baffles primarily control reflections inside the room; meaningful sound isolation between rooms may require changes to the complete wall, ceiling, floor, door, glass and services penetrations.
From Complaint to Measured Improvement
The process becomes more technical as the performance requirement increases.
We establish whether the priority is reverberation, intelligibility, confidentiality, external noise, impact noise, studio response or mechanical noise and identify the rooms / users most affected.
Acoustic design briefRoom dimensions, volume, ceiling, glass, flooring, wall finishes, partitions, doors, services and furniture are reviewed. Existing noise / RT measurements are incorporated where available.
Existing acoustic-condition mapTargets are chosen for the actual use. These may include reverberation time, absorption, partition isolation, speech privacy or specialist room criteria rather than one generic 'quiet room' target.
Acoustic performance briefWe decide where sound should be absorbed, scattered, blocked or separated and integrate those moves into furniture, ceilings, walls and zoning.
Acoustic concept planPanel type, thickness, mounting, air gap, slat / perforation pattern, partition build-up, doors, glazing and interfaces are developed to the level required for pricing and coordination.
Material / system scheduleAcoustic elements are coordinated with lighting, sprinklers, HVAC, AV, access panels and joinery before fabrication and installation.
Coordinated installed treatmentPerformance-critical projects can be measured after installation. Studio / listening rooms may need speaker or treatment tuning; offices may need reverberation / speech testing; isolation problems may require field testing.
Post-installation acoustic reviewAcoustic Metrics You Should Understand
These metrics help specify and verify acoustic design, but none of them alone describes the complete experience of a room.
Noise Reduction Coefficient is a single-number absorption rating measured using ASTM C423. Armstrong defines it from absorption at 250, 500, 1,000 and 2,000 Hz; an NRC above about 0.70 is commonly treated as high-performance absorption. A high-NRC wall panel can reduce reverberation but does not tell you how much sound will pass through the wall behind it.
Sound Transmission Class is derived from laboratory transmission-loss testing such as ASTM E90 and rated through ASTM E413. Higher values indicate greater attenuation of typical airborne building sounds. ASTM cautions that field performance can be lower than laboratory performance because of flanking paths and construction errors.
Reverberation time is the time required for sound to decay by 60 dB. ISO 3382-2:2008 remains current for measurement in ordinary rooms. As a design benchmark—not an Abu Dhabi code requirement—WELL publishes maxima of 0.6 s for conference rooms and 0.5 s for open workspaces.
ISO 3382-3:2022 evaluates open-plan offices using spatial decay of speech and speech intelligibility-related quantities, while ISO 22955:2021 gives acoustic-quality guidance for open offices and was reconfirmed in 2026. Ceiling absorption, screens, layout, distance and background sound all influence distraction and privacy.
For a rectangular studio or critical listening room, placing the listener around 38% of room length is a commonly used starting point to avoid some strong modal positions. It is not an exact optimum for every room; speakers, boundaries, construction and measurement can move the best final position.
Room proportions around 1:1.6:2.6 are often described as a golden acoustic ratio. Professional audio guidance notes that such ratios are secondary to other acoustic controls and are not worth rebuilding a normal room around unless the existing dimensions create serious modal problems. Existing rooms should be measured and treated rather than forced into a mathematical myth.
Two panels that look identical can perform differently because of core density, thickness, mounting cavity and tested frequency response. Specify the actual tested product and installation method instead of choosing a decorative panel only by its front finish.
In continuously cooled UAE interiors, diffuser velocity, duct breakout, fan vibration and equipment noise can affect speech clarity and recording quality. Where mechanical noise is the complaint, the acoustic interior strategy should be coordinated with the MEP / acoustic engineer rather than adding more decorative panels.
Abu Dhabi Codes, Fire Performance & Fit-Out Coordination
Abu Dhabi’s building framework continues to use the Abu Dhabi International Building Code and related building regulations as part of the emirate’s current professional / permitting system. DMT’s BINAA smart library identifies the ADIBC as the code setting minimum safety and construction requirements and continues to reference it in current professional qualification material. Acoustic changes that alter partitions, ceilings, doors or services therefore need to be coordinated within the applicable building and fit-out process.
The UAE Fire and Life Safety Code is the Civil Defence reference framework. Fixed wall and ceiling acoustic finishes, suspension systems, penetrations and assemblies can require documented fire performance depending on the occupancy and application. Product marketing terms such as 'fire-retardant' are not a substitute for the project consultant / authority confirming the required test classification and approved installation.
Acoustic Materials Can Be Part of the Interior Language
Colour selection should follow the interior concept, but acoustic material performance comes from the complete tested build-up. A felt colour or timber stain does not tell you the NRC, fire class or frequency response.
The HEX palettes below are conceptual Bella directions based on the supplied project research. They are not manufacturer fabric, powder-coat or veneer codes; final products should be selected from actual supplier samples.
Acoustic Cost & Programme
Current 2026 UAE pricing spans from small modular absorbers to engineered partitions and acoustic pods. Workspace UAE currently lists PET acoustic wall modules from about AED 12 to AED 152 per piece, fabric-wrapped desk panels around AED 150–230, movable acoustic partitions around AED 450–1,160 and enclosed acoustic pods from roughly AED 50,251 to AED 99,778. ebarza currently lists full-length fire-retardant slat acoustic panels around AED 1,015–1,175 per panel depending on size and finish. These are current retail / supplier references—not Bella quotations and not installed room prices.
Always ask whether an acoustic quotation is for absorption, sound isolation or both. Also check whether the price includes survey / testing, substrate preparation, suspension, edge trims, electrical / sprinkler relocation, fire stopping, access equipment, night work, VAT and post-installation testing.

Acoustic Interior Design Questions, Answered Properly
These answers separate room acoustics, sound isolation and common rules of thumb so you can choose the right intervention instead of simply buying more panels.
Acoustic design is the deliberate control of how sound is produced, reflected, absorbed, transmitted and perceived in a space. In interiors, it can include room shape, finishes, ceilings, partitions, doors, glazing, furniture, HVAC noise and specialist acoustic products.
Start with the room's use and complaint, then measure or assess dimensions, surfaces, noise sources and required privacy. Set a performance target, develop the layout, add absorption / diffusion where needed, improve isolation where sound transfer matters, coordinate MEP and then test or tune performance if the room is critical.
The core principles are absorption, reflection / diffusion, sound isolation and background-noise control. Absorption reduces reflected energy; diffusion scatters reflections; isolation limits transfer through the enclosure; and background / masking sound influences privacy and intelligibility. Good design balances them instead of maximising only one.
Building acoustics looks beyond one room to the complete structure: separation between occupancies, façade noise, floor impact noise, plant / mechanical noise, partitions, doors, glazing, flanking paths and room acoustics. Interior acoustic design is one layer within that broader building-acoustics strategy.
Useful categories include room acoustics, building acoustics / sound insulation, electroacoustics / audio-system design and environmental / noise-control acoustics. Projects such as studios or theatres often combine all four.
In architecture, acoustics describes how the built form and materials affect sound. Wall and floor construction influence transmission, while room geometry and interior surfaces influence reflections, reverberation and clarity. Mechanical systems and façade design can introduce or block additional noise.
Acoustic treatment changes the sound inside a room—typically by absorbing or diffusing reflections. Soundproofing / sound isolation reduces sound passing between spaces. A wall covered with high-NRC felt may sound less echoey yet still transmit speech if the wall, door or ceiling void is weak.
NRC means Noise Reduction Coefficient. ASTM C423 is the current test method used for sound absorption, and Armstrong defines NRC as an average absorption rating across 250, 500, 1,000 and 2,000 Hz. Higher NRC generally means more absorption; it does not measure how much sound a wall blocks.
STC means Sound Transmission Class. It is a single-number rating used to compare airborne sound isolation of walls and floor-ceiling assemblies. ASTM E90 provides the laboratory transmission-loss test and ASTM E413 provides the rating method. Installed performance can be lower because sound can flank around the tested assembly.
RT60 is the time required for sound to decay by 60 dB after the source stops. It is a key way to describe reverberation. ISO 3382-2 remains the standard reference for measuring reverberation time in ordinary rooms. The preferred value depends on volume and use rather than one universal number.
A room proportion around 1:1.6:2.6 is often called the acoustic golden ratio, but it does not guarantee perfect sound. Professional audio guidance notes that room ratios are secondary to speaker / listener position and acoustic control in most real rooms. Avoid obviously problematic cubic dimensions, then measure and treat the actual space.
It is a common starting guideline for placing the main listening position around 38% of the length of a rectangular room from the front wall. It aims to avoid some strong low-frequency peaks / nulls. It is not a universal optimum and should be refined using measurements or listening tests.
A professional fabric-wrapped absorber commonly uses a porous acoustic core such as mineral wool / fibreglass or tested PET, an acoustically transparent facing and a frame / mounting method that preserves the intended thickness and air gap. Commercial projects should use tested products with the required fire documentation rather than improvised combustible foam or fabric assemblies.
Treat panels as part of the composition: align them with joinery bays, artwork grids, desk zones or ceiling geometry; mix felt with timber slats; coordinate panel colours with upholstery; or use sculpted tiles as a feature wall. Placement should still follow the acoustic problem—decorative symmetry alone may miss the important reflection areas.
Current UAE supplier prices range widely. Workspace lists small PET wall modules from roughly AED 12–152 each and fabric-wrapped desk panels around AED 150–230. ebarza lists full-length decorative acoustic slat panels around AED 1,015–1,175 each. Installed commercial wall / ceiling systems cost more because framing, suspension, access, labour and coordination are added.
A current 2026 Dubai office guide places double-layer acoustic gypsum partitions around AED 150–220/m², double-glazed acoustic partitions around AED 550–900/m² and acoustic door sets around AED 4,000–8,000. These are third-party planning references; final cost depends on target performance, slab-to-slab construction, seals, penetrations and site conditions.
The required evidence depends on the occupancy, product, installation and approval route. UAE Fire and Life Safety requirements apply to relevant interior finishes and assemblies, so fixed wall / ceiling products should be selected with appropriate fire-performance documentation and confirmed by the project's consultant / authority. A supplier's 'fire-retardant' label alone is not a project approval.
