The A*STAR’s National Metrology Centre (NMC) is the national measurement institute of Singapore, dedicated to advancing measurement science for an innovative and competitive economy
NMC establishes, develops, maintains and disseminates the national measurement standards traceable to the International System of Units, providing key support to a wide spectrum of industry.
Achieving the nation’s highest level of physical measurement through close collaboration with leading national and international organisation.
With a multidisciplinary team of experienced scientists and engineers and state-of-the-art facilities, NMC provides dedicated services to industry partners to meet their specific needs.
NMC believes in working in close collaboration with industry partners, to create values for them and fuel growth for the industry.
The Acoustics & Vibration Laboratory develops, maintains and disseminates acoustics, ultrasound and vibration related national measurement standards in Singapore. They include airborne acoustics (20 Hz to 20 kHz), medical ultrasound power (100 mW to 1 W) and vibration (0.1 Hz to 350 kHz). Beyond measurement traceability dissemination, these measurement standards open up opportunities for local and overseas sensing instrument developers and manufacturers to understand their device performance through comprehensive characterization. We also carry out R&D for industry and other stakeholders to develop and apply acoustics and vibration measurement techniques for various applications.
Sound pressure level (decibel [dB]) is realised using laboratory microphones in a reciprocity calibration arrangement, according to the international standard IEC 61094-2.
Microphone calibration system
Sound level meters
The primary vibration standard is realised according to ISO 16063-11, using laser interferometry as an absolute reference. Standard Reference Accelerometers are calibrated against the primary standard. NMC is able to calibrate vibration transducers in the frequency range from 0.1 Hz to 350 kHz.
Services are provided for:
Primary & secondary calibration of vibration sensors
Vibration measuring instrument
The underwater hydrophone calibration standard is realised based on Section 14 of IEC 60565:2006 using a vibrating water column. The hydrophone calibration is done through comparison with a reference hydrophone where both units are subjected to the same hydrodynamic pressure field in the water column.
Services provided are:
Underwater calibration of hydrophones in the frequency range from 30 Hz to 2000 Hz.
Airborne calibration of hydrophones at the frequency of 250 Hz for selected models.
