WHA Laboratory
Consultancy – Testing – Research – Monitoring – Troubleshooting
Extension from consultancy services to laboratory testing allows acoustic systems, products and materials to be tested to prove their feasibility to clients and add value to projects. More and more innovative and green acoustic products are being developed to meet today’s demand for sustainable developments.
Our CNAS accredited laboratory, established in Huizhou China, consists of an acoustic and aerodynamic test rig, 8 reverberation rooms, and 5 acoustic test rooms purposely built for façade sound insulation testing, as well as acoustic and vibration equipment that enable our engineers to perform a wide array of testing, product development and analysis.
Acoustic and Vibration Performance Testing
WHA Laboratory is capable of conducting performance testing on acoustic and building products, such as sound absorption panels, silencers, acoustic windows and balconies, curtain walls, noise insulation panels, doors and partitions, ceilings, floor underlay and floating floors.
The laboratory is also able to conduct sound power measurements for equipment such as fan coil units and ventilation fans.
The physical performance of vibration isolators can also be determined in our test laboratory.
Site Testing and Commissioning
Design based on reliable test data as well as on-site testing to rectify any workmanship defects will always achieve the best results.
With extensive experience and advanced equipment, WHA Laboratory plays a key role in major projects for troubleshooting and commissioning by conducting field testing and inspection.
Field measurements are provided to assist our customers in validating the acoustic performance or noise levels of their products for quality acceptance.
Other on-site services that WHA offers include monitoring for noise and vibration, providing clients with real-time data to demonstrate compliance with requirements and regulations.
Calibration
Our testing and measurement equipment are calibrated by accredited calibration laboraories, such as ESG Matters, one of the HOKLAS accredited laboratory. This ensures that the testing and measurements conducted by WHA are accurate and reliable.

Acoustic Laboratory Testing
One of the biggest private owned laboratories in the world and accredited by China National Accreditation Service (CNAS) under registration number CNAS L8117.
To explore the secrets in acoustics, WHA Laboratory is known as “Acoustics Universe”. Inspired and built in accordance with the Law of Universe, the ‘Acoustics Universe” has 8 nos. of reverberation rooms named after the eight planets in our Solar System. As well as a silencer test rig is named as Galaxy, 2 nos. of novel test rooms is named as “Acoustics Space Shuttles” and Airflow Resistance Measurement Instrument is named as Pluto.
‘Acoustics Universe’ has obtained accreditation for over 70 items of testing standards. This allows WHA to provide a wide range of testing services and give clients quick and efficient test results.
