Shaanxi Jian Sheng Environmental Testing Co., Ltd.,简称Jian Sheng Testing, is an independent third-party testing, consulting, and R&D institution.

Shaanxi JianSheng Acoustic Technology Research Institute is the R&D Center of JianSheng Detection Co., Ltd., serving as the core technical department of JianSheng Detection.

The company, in partnership with Xi'an Jiaotong University, has jointly established a comprehensive acoustic laboratory in the northwest region, covering 1,800 square meters, with a chemical laboratory of 700 square meters and a mechanics laboratory of 200 square meters. We offer professional project consultation, design, and a product research and development center.

The acoustic laboratory is equipped with professional reverberation chambers, half-anechoic chambers, side-suppressed laboratories, wind tunnel muffler testing systems, and other specialized acoustic testing systems. It also incorporates the PULSE7767 data management system and 7702 order analysis software from Denmark's BK company, the full set of BK2270 systems including BK-DIRAC hall measurement software, the portable measurement and analysis system SA-AI from Japan's Rion, as well as the accompanying software; the CADNA-A building sound insulation simulation software from the United States; the INSUL building sound insulation performance prediction software; and the EASE building acoustic simulation software from Germany, among other acoustic testing and analysis systems and software.

The chemical laboratory is equipped with large-scale analytical instruments such as East-West gas chromatography, atomic absorption, ultraviolet spectrophotometry, and liquid phase equipment. The mechanical laboratory is fitted with several large and medium-sized mechanical testing machines and aging test chambers. All equipment has passed metrological calibration and verification by the China Metrological Academy. The company has sequentially obtained the CMA and CNCA metrological qualification and recognition, and authorization. The Jian Sheng Acoustic Technology Research Institute serves as our core technical research and project consultation and design organization, with 5 graduate students and 15 undergraduates. We also have a long-term advisory team consisting of experts from prestigious domestic universities such as Tsinghua, Tongji, and Xi'an Jiaotong Universities, ensuring our technical strength.

With our extensive experience in the field, we are able to provide comprehensive detection, consultation, and technical services in a wide range of industries such as automotive, home appliances, construction, materials, engineering projects, machinery and equipment, energy and chemical engineering, theaters, auditoriums, cinemas, hotels, and convention centers, industrial enterprises, transportation, and environmental protection. We guarantee you will receive highly satisfactory, scientifically-based acoustic performance, material properties, and environmental air quality assessments. Moreover, we are committed to making significant and outstanding contributions to the success of the project.
