A reverberation chamber is an essential laboratory facility widely used in acoustic testing and engineering. Unlike an anechoic chamber built for low sound reflection, a reverberation chamber is constructed with hard interior surfaces and well-designed cavity geometry to create a uniformly diffused sound field. It supports a variety of acoustic tests, including absorption coefficient measurement, sound power determination of noise sources, and supporting verification for sound insulation components. Many acoustic material manufacturers, home appliance producers, rail component suppliers and building acoustic testing institutes rely on reverberation chambers for product research and compliance testing.

A well-designed reverberation chamber is planned in accordance with relevant national and international standards. The cavity layout, enclosure structure, air sealing and arrangement of diffusers are carefully evaluated to promote sound diffusion and reduce measurement errors caused by standing waves. We provide customised solutions based on clients’ site conditions, test categories and target reverberation time, covering civil construction, sound and vibration isolation, diffuser fabrication and on-site commissioning. Building material suppliers often test acoustic panels, rock wool and sound-absorbing materials inside the chamber to collect real data for noise reduction design. Manufacturers of home appliances and motors carry out sound power tests for finished products to guide noise optimisation during new product development.

In building acoustic projects, reverberation chambers are frequently paired with sound insulation rooms to test airborne sound insulation of partitions, doors, windows and floor slabs. During project execution, our team conducts site surveys to review constraints such as floor load, ceiling height and utility routing, while reserving space for regular calibration and maintenance after handover. We support third-party verification and provide commissioning documentation upon completion. Our service covers compact reverberation cabins for research use and large-scale industrial chambers, to suit different long-term operational requirements.

The credibility of acoustic test data is closely tied to the sound field quality of the laboratory. The construction standard of a reverberation chamber shapes the reference data used for material evaluation and product noise improvement. With rich experience in acoustic laboratory construction, our team keeps familiar with global testing standards. We deliver one-stop services for research institutes, testing centres and manufacturing partners, from preliminary consultation and design development to on-site installation and acoustic tuning, helping clients build stable acoustic testing platforms.
