Noise interference from surrounding environments often distorts measured acoustic data during product research and testing. When manufacturers conduct noise measurement of components or finished machinery inside ordinary workshops, background noise and sound reflections will mix with signals from the test source, making it difficult to capture authentic acoustic characteristics of the equipment.

Constructed with sound absorption materials and vibration isolation foundations, the semi-anechoic chamber installs sound-absorbing structures on the ceiling and surrounding walls while keeping a hard reflective floor. It creates an acoustic environment close to a free sound field and supports noise measurement and sound power level testing for various sound sources.

It is widely adopted for acoustic verification across many industries, including home appliances, fans, motors, automotive components, small power equipment and electroacoustic devices. Teams can compare different noise reduction designs in the early product development phase and carry out acoustic sampling inspection during mass production. The chamber reserves proper ports for acoustic measurement and allows convenient movement and installation of test samples. The integrated vibration isolation setup helps weaken vibration transmission from outside and reduces disturbances to measurement results.

We provide customised design and construction services of semi-anechoic chambers according to site conditions, applicable testing standards and sample dimensions. Our service scope covers acoustic survey, on-site installation, commissioning and final acoustic performance verification. The chamber can comply with relevant national and international acoustic standards, supporting enterprises in product development and acoustic inspection work.
