Acoustic research and testing are easily affected by ambient noise and sound reflection, which may reduce the usability of collected data. As a core facility for acoustic laboratories, an anechoic chamber creates a near-free-field environment and helps enterprises and research institutions reduce environmental interference during acoustic tests.

With carefully arranged sound-absorbing materials inside, the anechoic chamber absorbs sound waves coming from all directions and greatly cuts down sound reflection within the space. Combined with vibration isolation structures, it weakens vibration transmitted from building structures and the ground. In this environment, sound emitted by test samples can be measured under conditions close to free field. It is widely adopted for acoustic tests of motors, fans, home appliances, automotive components and other products. Engineers can measure sound power and spectral features of sound sources, and carry out verification for noise reduction upgrades.

During product iteration, R&D teams often need to compare noise performance among different structural designs. Workshops and ordinary laboratories usually have unstable background noise and obvious reverberation, making it hard to obtain consistent test data. The anechoic chamber maintains stable acoustic conditions for repeated comparison tests, supporting the adjustment of noise control solutions. It is commonly used in development and certification tests for automotive electronic parts, small power equipment, speakers and acoustic sensors. We provide customized solutions based on site conditions, test items and applicable standards, including selection of sound-absorbing wedges, floating vibration isolation systems, noise-reducing doors and ventilation systems, balancing operational needs and maintenance convenience.

Projects can follow ISO 3745 and other international standards. We control background noise and free-field deviation during design and construction. Our service covers site survey, design, on-site installation, acoustic acceptance test and regular maintenance consultation, to help the laboratory keep stable acoustic performance over time.

Each project has unique requirements in terms of test categories, site height and load capacity. We adjust solutions according to actual working conditions to match the long-term R&D and testing plans of clients. A reliable acoustic environment lays a solid foundation for acoustic research. A well-designed anechoic chamber supports continuous noise control and acoustic optimization, assisting products to meet expected acoustic performance requirements.
