With the continuous growth in demand for medical device testing, the construction of high-standard acoustic laboratories has become a key driver for enhancing the capabilities of research institutions.
Guangdong Medical Devices Quality Surveillance and Test Institute is a highly influential research and testing institution in South China. It has long been engaged in medical device technology research, quality inspection, and standardization services. The institute has a strong foundation in performance evaluation, testing technologies, and industry services, undertaking numerous research and testing projects while providing solid technical support for the development of the medical device industry.
GZ DP Anechoic T&E Co., Ltd., as a professional service provider in the field of acoustic laboratories and artificial environment systems, has long been dedicated to acoustic environment design, engineering implementation, and technical services. The company operates a CNAS-compliant acoustic laboratory and has established a mature engineering system, offering full-process capabilities from solution design to project delivery.
Recently, GZ DP successfully won the bid for the semi-anechoic chamber project of Guangdong Medical Devices Quality Surveillance and Test Institute. The company will serve as the technical service and implementation provider, taking full responsibility for technical support and engineering execution of the semi-anechoic chamber system, ensuring high-standard project delivery.
The project aims to build a high-standard semi-anechoic chamber system for acoustic performance testing and evaluation of medical devices. As a critical component of acoustic testing systems, the performance of the semi-anechoic chamber directly affects the accuracy and reliability of test results and plays a vital role in scientific research, testing, and product validation.
