Zhaoqing Library’s Party-Building Exhibition Hall combines public reading, focused study, cultural display and multimedia communication in one open interior. The project required more than a visually unified fit-out: it needed a practical library acoustic design strategy that could moderate sound build-up without weakening the strong red-and-white exhibition identity.
The completed space uses the ceiling field, shelving, low partitions, furniture and spatial zoning as a coordinated interior system. Black linear ceiling slats visually connect the reading and exhibition areas, while the ceiling zone provides the most continuous location for acoustic absorption above hard floors and active visitor routes.
This case study is based on the supplied completion photographs. Exact room dimensions, absorber specifications, measured reverberation time and product model numbers were not supplied, so no unverified performance value is claimed.

The Design Brief: One Interior, Several Sound Expectations
A modern public library is not acoustically uniform. Visitors may read silently at a desk, discuss material in small groups, watch a video, move through an exhibition or pause beside an illuminated display. Each activity produces a different sound pattern and a different expectation of privacy.
The acoustic objective was therefore not to make every part of the hall silent. It was to create a controlled soundscape: quieter study positions should feel settled, conversation should not dominate the open floor, and exhibition or media content should remain locally intelligible.
This principle is consistent with current library-planning guidance. The State Library of New South Wales describes contemporary libraries as multi-use environments that must balance communication, privacy, sound isolation, background noise and the control of accumulated noise. Designing Libraries likewise emphasizes that good acoustics support communication where it is needed while reducing disruption in concentration zones.
Why the Space Needed Integrated Sound Absorption
The photographs show several features that can increase reflections if they are not acoustically balanced:
- A large, visually connected floor plate allows speech to travel between activity zones.
- Grey hard flooring is durable and easy to maintain, but it reflects footsteps, chair movement and conversation.
- Display walls, columns, tables and glazed openings add more sound-reflective surfaces.
- Reading, exhibition and multimedia functions may operate at the same time.
- The architectural ceiling includes lighting, air distribution and access requirements, limiting where visible treatment can be added.
These conditions make the ceiling plane especially valuable. In a library, sound absorption is most effective when it is distributed across the occupied area instead of concentrated in one decorative feature. A continuous overhead treatment can intercept energy from speech and movement before repeated reflections spread it through the open plan.
Ceiling-Led Library Acoustic Design
The black linear slatted ceiling is the dominant unifying element across the project. Its regular rhythm reduces visual clutter, complements the white structural beams and creates a consistent background for linear lights, downlights and decorative fixtures.
From an acoustic-design perspective, an open slatted ceiling can also serve as the visible face of an absorptive build-up. In this type of assembly, sound passes through the open joints and is attenuated by a porous acoustic layer installed above or behind the slats. The air cavity can further support absorption when its depth and backing are correctly specified.
For a comparable library ceiling, the technical specification should confirm:
- the acoustic absorber type, thickness, density and tested performance;
- the percentage and spacing of open joints between slats;
- the depth of the ceiling cavity;
- a dark, acoustically transparent backing that preserves the black visual field;
- continuity around lights, diffusers, access panels and structural edges;
- fire performance, indoor-air requirements and maintenance access.
The supplied project photographs confirm the linear ceiling geometry and coordinated services, but they do not identify the concealed absorber or its laboratory rating. The case therefore documents the design logic without assigning an unsupported product specification.
Quiet Reading and Study Zones
The dedicated study area places repeated desk positions beneath an evenly organized ceiling and lighting grid. Tables, chairs and shelving establish a clear behavioral cue: this is a concentration zone rather than a circulation or presentation zone.
Acoustically, the most useful design move is to control the space above the desks. Distributed ceiling absorption reduces the persistence of chair noise, page handling and low-level conversation. It can also limit the distance over which speech remains distracting, provided that the ceiling system, room geometry and background sound are designed together.
The study layout supports acoustic comfort in three additional ways:
- Consistent workstation spacing avoids crowding users into a single noisy cluster.
- Shelving around the perimeter breaks up large uninterrupted wall planes and creates a visual buffer.
- A distinct furniture language separates focused work from exhibition circulation without relying on full-height walls.
Zoning the Reading, Media and Exhibition Functions
Acoustic zoning begins with adjacency. Activities that tolerate speech and movement should be grouped together, while focused reading positions should sit away from doors, display narration, gathering points and main circulation routes.
In the Zhaoqing Library hall, furniture and display architecture help establish these transitions. Low sculpted dividers define seating pockets without closing the interior. Tall illuminated shelving forms stronger edges. The media wall creates a recognizable destination so its sound source can be managed locally instead of becoming ambient sound for the entire room.
These elements should not be treated as substitutes for tested sound isolation. Open shelving and low dividers can interrupt sightlines and influence sound paths, but they do not create the isolation of a sealed wall and door. Their greatest value is behavioral and spatial: they tell users where different activities belong and increase distance between incompatible uses.
Exhibition Acoustics Without Losing the Visual Story
The red-and-white exhibition sequence is designed as a strong narrative environment. Graphic panels, illuminated timelines and feature ceilings create visual focus around historical content. Conventional add-on acoustic panels could easily compete with this display language.
The project demonstrates a more integrated approach: keep the visible storytelling surfaces available for graphics and place the primary sound-control function in the ceiling and supporting interior elements. This allows the display walls to remain legible while the overhead field contributes to acoustic control.
Where an exhibition includes narration or video, loudspeakers should be selected and aimed for short listening distances. Directional coverage, sensible level limits and local user controls reduce spill into adjacent reading areas. If multiple programs operate simultaneously, the commissioning process should check actual playback content—not only test tones—because speech and music create different distraction patterns.
Coordinating Acoustics With Lighting, HVAC and Fire Services
The ceiling photographs show a dense technical layer: rectangular linear luminaires, recessed downlights, decorative star-shaped lights and mechanical outlets share the same architectural zone. Good acoustic performance depends on coordinating these components before installation.
Key details include:
- aligning lights with the slat module to avoid irregular cuts;
- maintaining absorber continuity around luminaires and ventilation terminals;
- preventing visible gaps in the black backing;
- providing removable sections for valves, dampers, wiring and future maintenance;
- controlling vibration or airflow noise from mechanical equipment;
- coordinating sprinklers, detectors and emergency devices with applicable codes;
- protecting acoustic materials from dust, damage and overspray during construction.
This is where a design-and-installation workflow adds value. When acoustic, interior, electrical, mechanical and exhibition trades resolve penetrations together, the finished ceiling reads as one intentional system rather than a collection of later modifications.
Installation Quality: Details That Determine the Finished Result
A linear ceiling magnifies small alignment errors. Uneven joint widths, wandering light lines or inconsistent perimeter gaps remain visible across a long room. The same defects can also create discontinuities in the concealed acoustic layer.
A robust installation sequence should therefore include:
- Survey the structural soffit and confirm finished ceiling levels.
- Coordinate the reflected ceiling plan with all service trades.
- Set out primary control lines through the longest visible axes.
- Install and protect the specified acoustic backing or absorber.
- Complete slats, trims and access panels with consistent spacing.
- Inspect penetrations, perimeter conditions and black-background continuity.
- Clean the ceiling and test lighting, ventilation and media equipment.
- Conduct acoustic and operational checks under realistic use conditions.
Mock-ups are particularly useful around light fixtures, columns, changes in ceiling height and exhibition thresholds. They allow the design team to approve the visual rhythm and confirm that the acoustic layer remains continuous before full production.
Performance Verification and Handover
Completion photography can demonstrate workmanship and integration, but it cannot prove acoustic performance. A proper handover should combine objective checks with user experience.
Depending on the project brief, verification may include:
- background-noise measurements with building services operating;
- reverberation-time measurements in representative occupied zones;
- checks of speech level and spatial decay across open reading areas;
- media playback tests at normal operating levels;
- listening checks for flutter echo or localized reflections;
- staff and user feedback after the space enters service.
ISO 3382-3:2022 provides measurement methods for spatial sound distribution in open-plan offices. It is not a library compliance standard, but its treatment of speech decay and distraction distance can inform a measurement strategy for comparable open shared interiors. Project-specific targets should always be set by the acoustic consultant and agreed with the client before testing.
Project Outcome
The completed Zhaoqing Library Party-Building Exhibition Hall presents a coherent public interior in which reading, study, multimedia and historical display share one architectural language. The linear ceiling establishes visual continuity, the furniture and shelving clarify activity zones, and technical services are integrated without overwhelming the exhibition experience.
The central lesson is straightforward: library sound absorption works best when it is planned as part of the interior architecture. Treating the ceiling, zoning, furniture, building services and media systems as one coordinated design reduces the need for visually disruptive corrections after opening.
No measured acoustic values were supplied for publication, so the outcome is described in terms of visible completion, functional organization and design integration rather than quantified performance.

FAQs: Library Acoustic Design
What is library acoustic design?
Library acoustic design is the coordinated control of reverberation, background noise, sound transfer and activity zoning so that reading, study, conversation, media and public programs can coexist with less disruption.
Where should sound absorption be placed in an open library?
The ceiling is often the largest uninterrupted treatment area, especially when the floor must remain durable and easy to maintain. Additional absorption may be distributed on walls, screens or furniture where it supports the room layout and design intent.
Can a linear slatted ceiling improve library acoustics?
Yes, when it is designed as a complete acoustic assembly. Open joints can allow sound to reach a tested porous absorber behind the slats. Slat spacing, backing, cavity depth, absorber specification and service penetrations all affect the result.
How should quiet and active library zones be separated?
Start with distance and adjacency, place circulation and media uses away from focused study, and reinforce the plan with shelving, partitions and furniture. Enclosed rooms with suitable walls, doors and seals are needed where true sound isolation is required.
What should be checked at acoustic handover?
Check background noise, reverberation, speech spread, media spill, mechanical noise and localized reflections under realistic operating conditions. Document measurement positions, occupancy conditions and equipment settings so the results can be interpreted correctly.
