Summary: xFusion Digital Technologies Co., Ltd. (xFusion) was established on September 13, 2021. The company’s main business is the design, R&D, and service of computing infrastructure, urbanenterprise digital intelligence, and smart energy solutions. Its main products include the FusionServer series of generalpurpose / AI / missioncritical servers, liquid cooling solutions, operating systems, and hyperconverged solutions, which are mainly used in cloud computing, digital transformation, AI computing, and other computingintensive scenarios.

Guangzhou Danpin Anechoic T&E Co., Ltd. is composed of a team of acoustic experts and professional engineers at home and abroad who have been engaged in various acoustic technology research for many years and have rich theoretical and practical experience. The company owns its own office building and factory. An acoustic laboratory meeting CNAS standards is built in the factory, which can monitor the acoustic technical indicators of its own products and provide acoustic testing services to the outside. Through the arduous efforts, continuous innovation and development of the Danpin team, the acoustic laboratories designed, produced, and installed by the company have products with accurate technical indicators, environmental friendliness, durability, beautiful appearance, and high technological content.

The semi - anechoic chamber is not only a special laboratory for acoustic testing but also an important part of the testing system. In fact, it is also one of the acoustic testing equipment, and its acoustic performance indicators directly affect the accuracy of the test.
