The 2025 Guangzhou International Exhibition on Architectural Acoustics and Noise Control (co-located with the "2025 Guangdong Modern Construction Industry Development Conference & Guangdong International Construction Industry Expo") successfully concluded at Area C of the China Import and Export Fair Complex in Guangzhou from November 27 to 29. GZ DP Anechoic T&E Co., Ltd. and  DC Acoustic Technology Research Co., Ltd. jointly participated in the exhibition, showcasing core acoustic solutions at Booth 14.1-F30a. Leveraging the synergistic advantages of "equipment + space + services," the two companies deepened exchanges with industry peers and received positive feedback.

 Highlights of Core Products & On-Site Exhibits  

• Acoustic Laboratory Segment

 - Airborne Sound Insulation Chamber : The lateral sound insulation of the laboratory is 6-15dB(A) higher than the actual sound insulation of tested products, ensuring precise sound insulation measurement of materials.  

- High-performance wedge-structured anechoic chambers.

 • Acoustic Instrument Segment  

- NI-DC PULSE Multi-Channel System : Supports synchronous analysis of sound pressure level, frequency spectrum, etc., covering quality control and scientific research.  

- DC-TS-NVH Abnormal Noise Detection System : Integrates an anechoic box for accurate evaluation of abnormal noise in mechanical and electrical components as well as automotive parts.  

• Vibration Damping & Materials Segment  

Vibration damping modules, acoustic metamaterials with high sound absorption coefficients (sound-absorbing wedges/flat panels), and detachable sound insulation materials suitable for floor laboratories, covering the entire process of "detection - treatment - optimization."  

On-Site Exchanges & Value Implementation  

During the exhibition, representatives from construction engineering firms, research institutions, and manufacturing enterprises conducted in-depth consultations focusing on core needs such as construction acceptance supporting solutions, custom R&D cycles for scientific research laboratories, and production line abnormal noise detection efficiency. Customer feedback not only provided clear directions for DP and DC to optimize service processes and adjust product adaptability but also led to preliminary cooperation intentions from some clients, thanks to the practicality and professionalism of the solutions.  

As professional service providers in the acoustic field, DP (specializing in the design and construction of acoustic laboratories compliant with CNAS, ISO 3745, and other standards) and DC (focusing on noise and vibration instrument R&D and laboratory supporting services) adopt a collaborative model. They offer integrated acoustic solutions for construction, scientific research, manufacturing, and other fields, precisely meeting the demand for "high-precision, full-process" acoustic technology in the modernization of the construction industry.

Acknowledgments & Future Outlook  

We would like to thank all guests, customers, and partners who visited Booth 14.1-F30a—your trust and exchanges are the core value of this exhibition. We also appreciate the team's professional support in ensuring the smooth progress of solution demonstrations and demand matching.
