With the continuous upgrading of the smart appliance industry, enterprises are placing higher demands on product quietness, sound quality performance, and R&D testing environments. High-standard acoustic laboratories are increasingly becoming important infrastructure for product innovation and quality improvement.

Suzhou Tineco Intelligent Technology Co., Ltd. has long focused on the smart cleaning appliance sector, continuously engaging in the R&D and manufacturing of smart vacuum cleaners, floor washers, and innovative household appliances, with solid market performance and brand influence in the industry.

GZ DP Anechoic T&E Co., Ltd., as a service provider in acoustic laboratories and artificial environment systems, has long focused on the construction of semi-anechoic chambers, full anechoic chambers, silent rooms, and acoustic testing systems. The company provides full-process services covering design, engineering implementation, delivery, and acceptance, and has served manufacturing enterprises and research institutions.

Recently, GZ DP successfully won the bid for the semi-anechoic chamber and silent room project of Suzhou Tineco Intelligent Technology Co., Ltd. The company will provide related system construction services for product R&D testing, noise analysis, and quality verification. The successful launch of the project reflects the solid cooperation foundation between both parties in project requirements, technical solutions, and implementation coordination.

Upon completion, the project will further enhance Tineco’s capabilities in noise reduction optimization, sound quality evaluation, motor noise testing, and airflow acoustic analysis, providing a stable and reliable testing environment for next-generation product development.
