As a complementary acoustic test facility alongside anechoic chambers, the reverberation chamber is engineered with highly reflective boundary surfaces. Sound waves reflect repeatedly inside the enclosure and build up a well-distributed diffuse sound field, which serves as a fundamental test environment for measuring sound absorption coefficients of materials and sound power levels of noise sources. It is built in accordance with widely recognised standards including ISO 3741, supporting acoustic research and testing for building, HVAC, home appliance, rail transit and other related industries across Southeast Asia.

Many material manufacturers, home appliance R&D teams and third-party testing laboratories face challenges in ordinary testing spaces. Unstable sound incidence and uneven sound distribution often lead to inconsistent measurement results after sample replacement, making it hard to evaluate the effect of formula modification or structural optimisation. The reverberation chamber is constructed with reflective surfaces and acoustic diffusers to reduce standing waves caused by parallel walls. Random sound incidence on test samples enables engineers to collect repeatable data for absorption performance, as well as sound power data for ventilation fans, range hoods, vacuum cleaners and air conditioning units. Building acoustic designers carry out tests on ceiling absorbers and noise reduction components inside reverberation chambers to support acoustic design and noise control planning for commercial and public buildings. Home appliance brands run noise evaluation for new product iterations, guiding teams to optimise air duct layout and vibration damping structures. Suppliers of rail transit components also use this facility to test ventilation units and onboard acoustic materials for compliance verification.

We deliver customised design solutions based on clients’ test objects, frequency ranges and site constraints. Our design scope covers chamber volume, diffuser arrangement, structural vibration isolation, acoustic door assembly and reserved interfaces for measurement instruments. After construction, we perform on-site commissioning and performance verification for reverberation time and sound field uniformity, helping clients establish standard-compliant acoustic laboratories. The chamber suits regular R&D testing, third-party inspection and product certification tests. We also support combined acoustic laboratory layouts together with anechoic chambers and transmission loss rooms, providing full services from design, fabrication, installation to after-sales maintenance for long-term stable operation.
