Measurement and monitoring of sound and vibration is critical in many industry sectors such as aerospace, construction, automobile, electronics, manufacturing and healthcare, as it has great impact on quality of products and services; performance and reliability of equipment; health and safety of the people.
NMC is expanding the acoustics metrology area to primary microphone calibration based on pressure-field reciprocity method. A secondary acoustic system based on free-field measurements will also be established.
The Acoustics & Vibration (AV) Laboratory develops, maintains and disseminates acoustics, ultrasound and vibration related national measurement standards in Singapore. 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. The acoustics and vibration metrology at NMC can be broken down into four areas namely airborne acoustics, underwater acoustics, ultrasound and vibration. These standards are derived from four base units which are ampere, metre, kilogram and second.
