Congratulations to Hengyang Honghua Electronic Technology on semi-anechoic chamber project acceptance!

Hengyang Honghua Electronic Technology Co., Ltd. was established in June 2021 and is located in Baishazhou Industrial Park Yanfeng District, Hengyang City. Covering an area of 17,000 square meters, the company focuses on the R&D, production, and sales of brushless cooling fans. Its products are mainly applied in fields such as e-sports gaming, home appliances, communications, industrial communications, and servers, with a market covering mainland China,, Europe, the United States, and other regions. The company has its headquarters in Dongguan City, Guangdong Province, and has initially invested $6 million in the construction of production. Hengyang Honghua Electronic Technology Co., Ltd. was recognized as a national high-tech enterprise in 2024, and was rated as a provincial enterprise technology center and a provincial innovative small and medium-sized enterprise in 2025.

Guangzhou DP Anechoic T&E Co.,Ltd.is composed of a group of domestic and foreign acoustic experts and professional engineers who have been engaged in various acoustic technology research for many years and have rich theoretical and practical experience. It has its own office buildings and factories, and the factory has acoustic laboratories in line with CNAS standards, which can monitor the acoustic technical indicators of its own products and carry out acoustic testing services. Through the hard work and continuous innovation and development of Danpin team, the acoustics laboratory designed, produced and installed by Danpin has products with accurate technical indicators, green environmental protection, durable quality, beautiful appearance and high scientific and technological content.GZ DC Acoustic Technology Research Co., Ltd., an affiliated company of GZ DP, is a high - tech company specialized in the research and development of acoustic testing instruments. The acoustic environment provided by DP can be perfectly and seamlessly integrated with the testing instruments of DC. Therefore, it can offer a complete solution for acoustic laboratories.

Semi-anechoic chamber is not only a special laboratory for acoustic testing, but also an important part of the test system, in fact, it is also one of the acoustic testing equipment, and its acoustic performance indicators directly affect the accuracy of the test.The Noise and Vibration Analyzer is an instrument specifically designed based on a multi - functional data acquisition (DAQ) module. It can measure, collect, and analyze noise and vibration with high precision. It provides more detailed product quality inspection data for engineering technicians and quality supervision managers. The operation is simpler, and it also offers guiding suggestions for product research and development design, production technology, and quality control. For follow-up information such as specific acoustic design, manufacturing, construction and installation, and brief introduction of site measurement and acceptance, please pay attention to visit the project case on the official website, or scan the QR code of the wechat public service number to get a free push, and for detailed information, please go to the download center of the official website for free download.

I.Procurement content

   semi-anechoic chamber；

II.According to the standard

GB/T 6882 "Acoustic noise source sound power level determination anechoic chamber and full anechoic chamber precision method"

ISO3745 "Acoustics - Determination of sound power level of noise source - Precision determination method of anechoic chamber and total anechoic chamber"

III.Main indicators and project contents

When the external environmental noise: Len (A)≤60dB (A), there is no abnormal interference around (such as smashing the ground, piling, impact) and the air conditioning and ventilation system is turned off, and only the lamps are turned on, the indoor noise floor of the semi-anechoic chamber: Lgn(A)≤10dB(A)

Cut-off frequency: Fc≤80Hz.

Meet the indoor background noise value Lgn(A), sound insulation, sound absorption and noise reduction, dimensions, and other relevant details agreed upon by both parties
