Preserving the Voices of Ancient Texts with Technology, Microperforated Panels Create a National Cultural Sanctuary .

As a national cultural project that carries the function of collecting, displaying and researching the classics of Chinese civilization, the National Version Museum in Conghua, Guangzhou has attracted much attention since its completion for its grand architectural aesthetics and profound cultural connotations. In the construction of this cultural palace, the innovative breakthroughs in architectural acoustics design and material application have also played a significant role.

Among them, the microperforated acoustic panels independently developed by our company, with their outstanding acoustic performance and artistic expression, have become an important support for optimizing the acoustic environment in the core functional areas of the venue, providing a solution that integrates technology and humanity for academic exchanges and public experiences.

The Acoustic Challenges of the National Version Library

From "Silence" to "Integration" Wisdom
As a national-level cultural venue, the National Version Library in Conghua, Guangzhou integrates multiple functions such as collection, exhibition, academic research, and cultural exchange. Its acoustic design must take into account the complex demands of various scenarios:
 

Academic spaces :

Lecture halls and meeting rooms need to achieve clear speech intelligibility and uniform sound field.
 

Public exhibition halls :

It is necessary to balance the control of crowd noise and immersive exhibition experiences.
 

Architectural aesthetics :

Acoustic materials need to blend with the traditional Lingnan architectural style and modern design language.
 

Facing multi-dimensional acoustic requirements, traditional sound-absorbing materials often struggle to simultaneously meet functional, environmental, and visual aesthetic demands.
 

Our company's microperforated acoustic panels, through material innovation and process upgrading, have provided a systematic solution for this national-level project.
 

Innovative Breakthrough: The Three Core Values of Microperforated Acoustic Panels
 

1. Precise Acoustic Control, Empowering Space Functionality
The product features natural wood veneer and a micro-pore resonance structure. Through precisely calculated pore size distribution and the depth of the cavity behind, it efficiently absorbs low-frequency noise (NRC ≥ 0.9), while also considering the impedance of mid and high-frequency sound waves. In scenarios such as the academic lecture hall and rare book reading area of the library, it significantly reduces reverberation time, enhances speech intelligibility and acoustic environment comfort, creating an "audible and undisturbed" acoustic environment for academic discussions and rare book studies.
 

2. Natural aesthetic expression, paying tribute to cultural heritage
The product surface is made of natural wood veneer, preserving the original texture and warm feel of the wood. Through customized dyeing techniques, it achieves a color harmony with traditional elements such as rosewood and blue bricks within the venue. The micro-pores are presented based on the "invisible acoustic" concept, with a pore diameter of 0.5mm. This ensures the efficiency of sound wave penetration while also ensuring that the pores blend seamlessly with the wood grain when viewed from a distance, perfectly integrating into the spatial narrative of the "Oriental Academy" style of the version hall.
 

3. Green technology as a safeguard, practicing the concept of sustainability
The base material is made of high-density fiberboard without formaldehyde addition, and the wood veneer sources are all FSC forest certified, echoing the ecological design orientation of the version hall from the raw material end.
The micro-hole structure is precisely carved by CNC machine tools, avoiding the dust pollution of traditional punching processes. The installation process is glue-free, achieving low-carbon and environmental protection throughout the entire life cycle.

The national-level project sets an industry benchmark
The Guangzhou Conghua National Version Museum project has undergone multiple rounds of expert deliberations and on-site tests in the selection of acoustic materials, standing out among numerous competitors.
 

The project's chief engineer commented: "The microperforated acoustic panels not only address the acoustic pain points of large-scale cultural public buildings but also achieve the unification of 'invisible technology' and 'visible aesthetics', providing an innovative model that can be replicated for the industry."

Conclusion: Safeguarding Cultural Heritage with Acoustic Technology
 

The completion of the National Version Center in Conghua, Guangzhou, marks not only a milestone in China's cultural soft power construction but also serves as a model case for the innovative application of architectural acoustics. Our company will continue to focus on the research and development of acoustic materials, empowering cultural spaces with technology, ensuring that every sound vibration resonates in harmony with the inheritance of civilization.
