The Lishui Town Party and Community Service Center in Foshan is not a conventional office. It combines public-facing service counters, staff work areas, training and meeting rooms, reading facilities, exhibition walls and circulation zones in one busy civic environment. Its office acoustic design must therefore support clear communication, appropriate speech privacy and comfortable noise levels across several different activities.
This case analysis examines the completed spaces documented in LEEYIN’s project archive and explains the acoustic priorities visible in the layout. The central lesson is simple: a mixed-use public office needs a zoned acoustic strategy. A training room, service desk, reading room and open lobby should not be assigned the same acoustic target or treated with one generic material.

What Is Office Acoustic Design?
Office acoustic design coordinates absorption, sound insulation, space planning, background noise and building services so people can communicate clearly without unnecessary distraction or loss of privacy. In a public service center, the design must also manage visitors, queues, training events, amplified speech and quiet reading within the same building.
A Civic Office Designed for Continuous Public Use
Public reporting states that the center opened in October 2022 in the Jinfengzhou area of Lishui Town, close to the Guangzhou–Foshan boundary. It was described as Nanhai District’s first town-level Party and Community Service Center and as a hub for coordinating local Party and public-service resources.
The center adopted a “997” service model, extending opening to 9 p.m. and operating seven days a week. Reports also state that its Guangzhou–Foshan service window can process more than 340 administrative matters. These operational facts matter acoustically: longer hours, varied visitor numbers and overlapping activities increase the importance of durable finishes and stable sound quality under changing occupancy.
The wayfinding lobby combines a hard floor, a smooth ceiling, wall displays, loudspeakers and long circulation paths. Such spaces can reflect voices and movement noise over distance. The project photographs do not provide a reverberation measurement, but they show why acoustic control should be integrated with the interior design instead of added only after staff or visitors report problems.
Why One Building Needs Several Acoustic Zones
The center brings together activities with conflicting sound requirements:
- Service counters need easy face-to-face communication but should limit how far personal conversations travel.
- Training and conference rooms need clear speech at every seat, whether the source is a lecturer, microphone or loudspeaker.
- Reading rooms need low disturbance and controlled sound from adjoining public areas.
- Exhibition and circulation zones must handle groups, movement and informal conversation without excessive reverberation.
- Staff offices and consultation rooms may require concentration, confidentiality and separation from public activity.
An effective plan therefore begins with activity mapping. Each zone receives an appropriate target for reverberation, background noise, speech privacy and sound insulation. Adjacencies are then checked so a noisy function does not share an untreated boundary with a quiet or confidential room.
Training Room Acoustic Design: Speech Before Spectacle
The training room is the clearest speech-critical space in the image set. It contains multiple rows of seating, a lectern, desk microphones, wall-mounted loudspeakers and a large front display. The room is likely used for meetings, instruction, presentations and group discussion, all of which depend on intelligible speech.
In a speech room, excessive reverberation causes syllables to overlap. A sound system can make the room louder, but it cannot fully correct a long or uneven decay. The room-acoustic treatment should therefore work before amplification:
- Control the overall reverberation time with sufficient absorption.
- Distribute absorption so one part of the room is not acoustically “dead” while another remains reflective.
- Avoid parallel hard surfaces that can produce flutter echo.
- Coordinate loudspeaker aiming with seating and room geometry.
- Keep HVAC and equipment noise low enough that speech does not need to compete with the background.
Walls and Ceiling as One Acoustic System
The photograph shows a predominantly light ceiling, dark linear edge features and wood-finish wall panels. Their exact construction is not documented. If the wood-finish areas are intended to absorb sound, the panel perforation or slot pattern, backing layer, cavity depth and installation quality would all influence performance. If they are solid decorative panels, absorption would need to come from other surfaces.
Ceiling design is especially valuable in a meeting room because it can provide a large, evenly distributed treatment area. However, lighting tracks, air diffusers, sprinklers, access panels and loudspeakers can interrupt the acoustic field. Coordination should happen before installation so that services do not remove critical treatment area or create unwanted noise.
Public Service Counter Acoustics: Clarity Without Broadcasting
The service desk is where staff and residents exchange information, ask questions and potentially discuss personal matters. The acoustic objective is not silence. It is to make conversation easy at the counter while limiting unnecessary transmission to the next visitor or across the room.
Hard counters, floors, wall panels and ceilings can reinforce speech and increase the distance over which it remains intelligible. In a busy period, multiple voices may combine into a rising background level, causing people to speak more loudly and further increasing noise.
A public service counter strategy can include:
- absorptive ceiling treatment above the counter and waiting area;
- wall absorption away from reach or protected by durable finishes;
- sufficient spacing or partial screening between consultation positions;
- queue layout that keeps waiting visitors away from active conversations;
- local sound masking only where appropriate and professionally commissioned;
- enclosed rooms for sensitive or extended consultations;
- quiet printers, ventilation outlets and electronic equipment.
Speech privacy cannot be guaranteed by decorative absorption alone. Absorption reduces reflected sound, while privacy also depends on distance, barriers, background sound, room separation and staff operating procedures.
Open Public Areas: Controlling Reverberant Build-Up
The second-floor photograph, timestamped July 1, 2022, documents the interior during completion work. It shows a broad open area with a hard continuous floor, a largely smooth ceiling and several connected activity zones. In a space like this, sound can travel around partitions and along circulation routes unless absorptive surfaces and spatial breaks are deliberately introduced.
The acoustic design should consider both the total absorption and its location. A highly absorptive feature in one corner will not necessarily control a long path elsewhere. Treatment is more effective when it is distributed across the ceiling, selected walls or freestanding elements near the sources and paths that matter.
Reverberation Control Is Not Soundproofing
These terms are often confused:
| Acoustic task | Main purpose | Typical approach |
|---|---|---|
| Reverberation control | Reduce reflected sound inside the same space | Absorptive ceilings, wall panels, baffles and furnishings |
| Speech privacy | Reduce the intelligibility of conversations at unintended positions | Distance, barriers, zoning, absorption, masking and enclosed rooms |
| Sound insulation | Reduce transmission between separate rooms | Massive or multilayer partitions, sealed doors, ceilings, glazing and junctions |
| Noise control | Reduce equipment or services sound | Quieter equipment, isolation, duct attenuation and airflow design |
A successful office acoustic design combines these tasks instead of expecting one acoustic panel to perform all of them.
Exhibition and Circulation Areas: Acoustic Finishes That Support the Interior
The curved display wall and integrated lighting create a strong civic identity. From an acoustic perspective, curved and angled surfaces can redirect reflections, but shape alone does not guarantee absorption or eliminate echo. The finish, panel joints, backing construction and surrounding surfaces determine how the wall behaves.
Exhibition corridors also have practical durability requirements. Materials may be touched, cleaned and exposed to high traffic. Acoustic finishes in public areas should therefore be selected for:
- verified absorption within the completed assembly;
- fire performance appropriate to the building and location;
- emissions and indoor-air documentation;
- resistance to impact, cleaning and surface wear;
- integration with signage, lighting, doors and access panels;
- repairability and color consistency.
The photograph supports a visual observation—continuous wood-finish panels with integrated exhibition graphics—but not a product-performance claim.
Reading Room Acoustics: Protecting a Quiet Activity
The reading room combines full-height bookshelves, a timber-finish ceiling, integrated lighting and tiered bench seating with cushions. Books and irregular shelf contents can scatter sound, while cushions add limited local absorption. These features can help the room feel less reflective than an empty hard box, but they are not a substitute for a verified acoustic ceiling or wall system when a specific target is required.
The primary design challenge is often noise entering from adjacent public areas. Useful measures include:
- locating the room away from service counters and major circulation paths;
- using a door and surrounding partition with suitable sound insulation;
- sealing perimeter gaps and service penetrations;
- controlling mechanical noise from grilles and fan-coil units;
- adding distributed absorption to reduce movement and conversation noise inside the room;
- avoiding loud equipment directly beside reading seats.
The best reading-room acoustic design controls both internal reverberation and external intrusion.
Cultural Rooms and Feature Ceilings
Feature ceilings can carry architecture, lighting and identity while still contributing to room acoustics. The oath-room photograph shows a sculpted circular ceiling with an illuminated emblem, surrounding light slots, air grilles and adjacent wood-finish walls.
Complex ceiling geometry needs early coordination. Acoustic treatment must not obstruct lighting or ventilation, and service openings should not create rattles or bypass sound-insulating construction. Where speech or group recitation occurs, the design should also prevent strong late reflections from the curved ceiling and surrounding walls.
Enclosed Offices and Consultation Rooms: Isolation at the Boundaries
Absorption improves conditions within a room, but private offices and consultation spaces need sound insulation at their boundaries. Weak points commonly include:
- lightweight partitions that stop at a suspended ceiling instead of the structural soffit;
- unsealed gaps around cable trays, sockets and pipe penetrations;
- doors without perimeter or drop seals;
- shared return-air paths between rooms;
- glazing or frames with lower performance than the surrounding wall;
- back-to-back electrical boxes;
- rigid junctions and flanking paths through ceilings or floors.
For confidentiality, the complete wall-door-ceiling-services assembly should be evaluated. A high-performing wall cannot compensate for an open grille or a poorly sealed door.
HVAC, AV and Building-Services Noise
The photographs show air grilles, loudspeakers, microphones, displays and ceiling services in several rooms. These systems influence the acoustic result even when the architectural finishes are well designed.
Low background noise supports speech clarity and concentration, but an extremely quiet open office may make nearby conversations more distracting. The appropriate background should be stable, spectrally balanced and matched to the activity. Designers should check:
- fan and diffuser noise at occupied positions;
- duct-borne sound between rooms;
- equipment vibration transmitted through walls and ceilings;
- rattles around grilles, displays or access panels;
- loudspeaker coverage and delay;
- microphone gain before feedback;
- control-system and projector noise in training rooms.
AV commissioning should occur after the room finishes and furniture are substantially complete because these elements affect the final sound field.

Office Acoustic Design Checklist for Similar Public Buildings
Planning
- Map public, collaborative, quiet and confidential activities.
- Separate high-traffic sources from reading and consultation rooms.
- Define acoustic targets by space rather than one target for the whole building.
- Coordinate the acoustic brief with occupancy, opening hours and visitor peaks.
Design
- Calculate the absorption required for each room volume and use.
- Distribute treatment across effective surfaces.
- Detail partitions, doors, glazing and services as complete sound-insulating systems.
- Coordinate ceilings with lighting, sprinklers, HVAC and AV equipment.
- Select durable, cleanable and documented materials for public areas.
Construction
- Approve representative material samples and full build-ups.
- Inspect backing, cavities, joints and edge details before they are concealed.
- Seal penetrations and check door hardware.
- Protect acoustic finishes from paint, dust, impact and unauthorized substitution.
- Photograph concealed work and record product batch information.
Commissioning
- Measure reverberation time in representative ordinary rooms using an appropriate method such as ISO 3382-2.
- Check speech clarity and sound-system coverage in the training room.
- Review privacy at service counters and consultation rooms under realistic occupancy.
- Measure background noise from HVAC and equipment.
- Record room conditions, measurement positions and acceptance criteria.
Measurement and Verification
ISO 3382-2:2008 specifies methods for measuring reverberation time in ordinary rooms, including the measurement procedure, equipment, positions and reporting. It is relevant to offices, training rooms, reading rooms and public halls when reverberation needs to be compared with a project requirement.
ISO 22955:2021 provides guidance for acoustic quality in open office spaces, including offices that receive the public or combine several activities. Its activity-based approach is useful when planning public-facing work areas, although the project team must still establish criteria appropriate to local regulations and the actual service-center layout.
The supplied evidence does not include a commissioning report, so this article does not claim that the center was measured to either standard.
Lessons from the Lishui Town Service Center
The project photographs reveal five transferable lessons:
- Treat the building as a network of acoustic zones. Public service, training, reading and exhibition activities require different conditions.
- Prioritize speech in meeting rooms. Reverberation control and low services noise should be established before relying on amplification.
- Balance clarity and privacy at service desks. Face-to-face speech must be easy nearby but should not travel unnecessarily.
- Coordinate acoustic and visual design. Wood finishes, feature ceilings, signage and lighting can form one interior language, but acoustic performance must be verified in the complete assembly.
- Commission the finished space. Product data alone cannot prove the performance of installed ceilings, walls, doors, junctions and services.
Conclusion
The Foshan Lishui Town Party and Community Service Center demonstrates why office acoustic design for a civic building must go beyond conventional workplace noise control. Its public counters, training room, reading area and exhibition spaces create different and sometimes competing acoustic needs.
The right response is an activity-led, zoned strategy that combines reverberation control, speech privacy, sound insulation and low-noise building services. When those elements are coordinated with the interior architecture and verified after installation, a public service center can remain clear, welcoming and comfortable throughout a long operating day.
Planning a civic office, public service hall or mixed-use community center? LEEYIN can help review the room functions, identify noise paths and develop a project-specific acoustic design and material strategy.
Frequently Asked Questions
Why is office acoustic design important in a public service center?
A public service center combines staff work, visitor conversations, waiting, training and community activities. Without acoustic zoning, voices and movement can spread between functions, reducing speech clarity, concentration and privacy. A coordinated design gives each space the conditions required for its actual activity.
What is the main acoustic goal for a training room?
The main goal is intelligible speech at every occupied position. This requires controlled reverberation, low background noise and even loudspeaker coverage. Amplification can increase level, but it cannot fully correct excessive sound decay, flutter echo or noisy ventilation.
How can a public service counter improve speech privacy?
Use absorptive ceilings and walls to reduce reflections, provide distance or partial barriers between positions, organize queues away from conversations and offer enclosed rooms for sensitive matters. Sound masking may help in suitable layouts, but it must be professionally designed and commissioned.
Are wood wall panels automatically acoustic panels?
No. A wood-look surface may be solid decoration or part of an absorptive system. Performance depends on perforations or slots, open area, backing material, cavity depth and installation. Product data and construction details are required before an absorption claim can be made.
How should office reverberation time be verified?
Representative rooms can be measured after completion using a suitable procedure such as ISO 3382-2:2008. The report should identify the room condition, equipment, source and receiver positions, frequency results and the project criterion used for acceptance.
