Client Case Study: Acoustic Renovation Project for a Well-Known Cosmetics Company's Guangzhou Regional Headquarters

Project Background
In 2022, a renowned international cosmetics company sought a comprehensive acoustic solution for its Guangzhou regional headquarters. This multinational corporation, with over 80,000 employees worldwide and annual sales exceeding €30 billion, adheres to two core principles in its operations: a commitment to employee health and well-being and a steadfast determination to practice sustainable development. The client's goal was to ensure carbon neutrality in its operations and supply chain.

The regional headquarters was located in the core business district of Zhujiang New Town, Guangzhou. The entire office building needed a work environment that was both aesthetically pleasing and met the comfort needs of its employees. The project was large and complex, involving open-plan offices, meeting rooms, a cafeteria, a yoga room, and multi-functional activity rooms, requiring a large number of customized products and environmentally friendly installation solutions.

Challenge: The Acoustic Dilemma of Glass Curtain Walls
In modern office space design, glass curtain walls and open layouts have become mainstream. However, while this design brings advantages in transparency and lighting, it also creates potential acoustic hazards.

The client's Guangzhou headquarters features numerous meeting rooms and office areas with glass walls. Behind this aesthetically pleasing design, echoes and the diffusion and leakage of conversations have become significant challenges. Especially in areas with large glass walls or adjacent meeting rooms, the structural characteristics make echoes particularly pronounced, creating noise that leads to decreased employee concentration and difficulty in hearing conversations.

Furthermore, remote conferencing has become the new normal. Employees participating in online meetings reported: "The echoes are too strong, I can't hear the meeting room clearly," and "I can't understand what the other person is saying at all." These problems severely impact the communication quality and team collaboration efficiency of remote meetings.

In addition, different functional spaces have different acoustic requirements:

Open-plan office areas: require a balance between collaborative communication and focused work.

Meeting rooms: require ensuring both clear speech and privacy.

Cafe and yoga room: require creating a comfortable and relaxing atmosphere.

Multi-functional activity rooms: require flexible acoustic solutions to accommodate different activities.

The client urgently needs an acoustic solution that can comprehensively address these issues.

Solution: A Powerful Alliance of Professional Team and High-Quality Products

To address these complex acoustic challenges, the client engaged a world-renowned acoustics consulting firm. This firm has provided professional acoustic services to a range of internationally acclaimed companies, including Hilton, Marriott, Johnson & Johnson, and JC Decaux.

During the design phase, the team conducted comprehensive acoustic studies, assessing optimal acoustic targets for each area and outlining the necessary materials, quantities, and specifications. After rigorous screening and evaluation, the design team and acoustics consultants focused on outstanding local suppliers in China. Following on-site visits and product testing at multiple manufacturers, they ultimately selected us—a professional polyester fiber sound-absorbing panel manufacturer based in Guangdong—as their core acoustic material supplier. Key considerations include:

Superior Acoustic Performance: Our products achieve a Noise Reduction Coefficient (NRC) of over 0.8, effectively reducing echo by approximately 80%, meeting professional acoustic design requirements.

Excellent Environmental Attributes: Our products are made from up to 75% recycled materials (such as PET bottle flakes), making them 100% recyclable.

Safety and Health: Formaldehyde testing meets EO standards, and flame retardant performance passes European 3501-1 Class B testing and American ASTM-084 Class A standards.

Customization Capabilities: We offer a wide range of colors and engraved patterns to meet spatial aesthetic needs.

Localized Service Advantages: As a Guangdong-based company, we can provide faster response times, more flexible logistics, and more convenient on-site services.

Ultimately, we provide our clients with comprehensive acoustic solutions, including standard acoustic panels, engraved acoustic panels, natural fiber acoustic panels, and ceiling acoustic spraying.

Implementation: Tailor-made Acoustic Solutions
Diverse Applications of Polyester Fiber Acoustic Panels
We have installed a large number of customized polyester fiber acoustic panels throughout the office building. These acoustic panels utilize low-emission, environmentally friendly adhesive backing for installation, ensuring both excellent acoustic performance and aligning with the client's sustainability goals.

We offer a variety of product forms to meet the acoustic needs of different spaces:

Standard Acoustic Panels: For basic sound absorption in open-plan office areas and corridors.

Carved Acoustic Panels: Some panels feature two-tone carved patterns, perfectly matching the existing office design.

Innovative Solutions for Movable Partitions
Multifunctional activity rooms were one of the challenges of the project. This space required flexible layout adjustments for different activities such as all-hands meetings, training courses, and team building.

We provided custom-designed acoustic panels, installed on movable partitions. These movable partitions, with acoustic panels installed in each section, flexibly divide the space, effectively reduce noise interference between different areas, and increase design creativity.

Organic Integration of Natural Fiber Acoustic Panels
To enrich the material layers of the space, we also offer Eco Fiber natural fiber acoustic panels made from coconut fiber. These natural fiber acoustic panels, ranging in thickness from 30mm to 60mm, are integrated into the backing panels of polyester fiber acoustic panels, creating a seamless blend with the polyester fiber acoustic panels installed throughout the office building.

Eco Fiber natural fiber acoustic panels are made from 100% natural materials, achieving optimal sound absorption while perfectly complementing the printed surface of the polyester fiber acoustic panels.

Supplementary Treatment for Ceiling Acoustic Spraying
To complement the wall acoustic treatment and ensure good acoustic balance, we applied ceiling acoustic spraying to multiple areas of the office building. This special ceiling spray coating, composed of sound-absorbing microfibers, creates a soft surface that significantly reduces noise bounce back into specific rooms or areas. After spraying, a paint finish is applied to ensure a harmonious integration with the color scheme and design of each room.

Results: Quantifiable Acoustic Improvement
After project completion, we tested and evaluated the acoustic performance of several key spaces.

Acoustic Data Verification

Referring to data from similar glass conference room cases, reverberation time tests conducted before and after the installation of sound-absorbing materials showed:

Before installation: The average reverberation time for the corresponding human voice frequency band (500-1000Hz) was 0.89 seconds, generally higher than the recommended value of 0.6 seconds for conference rooms.

After installation: The average reverberation time decreased to 0.64 seconds, with almost all conference rooms reaching the ideal standard of below 0.6 seconds.

This means that employees' speech intelligibility during meetings is significantly improved, and the sound quality of online meetings is also noticeably enhanced.

Employee Feedback

After installation, employee feedback was extremely positive:

"The quality of conversations during meetings has improved."

"The discomfort of echoes is gone, making it much more comfortable."

"I can clearly feel the echoes being absorbed."

"It's easier to concentrate."

The client's project manager commented: "We are very grateful for the strong support from the local supplier team, engineers, and construction partners in Guangdong. This product is not just a sound-absorbing material; it also provides privacy and aesthetic appeal while maintaining the openness of the glass wall. As a solution to enhance the overall spatial experience, it is truly very effective. Special thanks to the local team for their rapid response and professional service, which allowed the project to proceed efficiently."
