Introduction: Dongke Yanfeng (Guangzhou) Seat System Co., Ltd. is a joint venture jointly funded by Yanfeng International Seat System Co., Ltd., Dongfeng Electronic Technology Co., Ltd. and Yanfeng Automotive Trim Systems Co., Ltd. Its principal operations revolve around the product design, development, testing, manufacturing and sales of automotive complete seats and frames, furnishing professional matching automotive seats and components for vehicle manufacturers. The company has its headquarters situated in Huadu District, Guangzhou, and also maintains branches in Zhengzhou and Xiangyang. 

GZ DP Anechoic T&E Co., Ltd. is composed of a team of acoustic experts and professional engineers. These individuals have dedicated many years to diverse acoustic technology research, both within the country and abroad, amassing rich theoretical and practical know-how. The enterprise possesses an office building and a factory. Within the factory precincts, an acoustic laboratory conforming to CNAS standards has been erected. This facility empowers the monitoring of the acoustic technical parameters of the products produced by the company and extends acoustic testing services externally.Owing to the painstaking efforts and unceasing innovation and progress of the Danpin team, the acoustic laboratories engineered, fabricated and installed by them showcase products with exacting technical metrics, environmental compatibility, sturdiness, aesthetic appeal and high-tech sophistication. 

The semi-anechoic chamber functions not merely as a specialized acoustic testing laboratory but also as a pivotal constituent of the testing apparatus. In essence, it constitutes one of the acoustic testing implements, with its acoustic performance benchmarks directly dictating the testing precision.
