Acoustics and Vibration Group was established in 1998 as illustrates in Figure 1.  Our main responsibility is to maintain the primary standard of acoustics, vibration, and ultrasound metrology and its traceability. We also develop new capabilities to support our customers’ needs for example microphone calibration, sound calibration calibration, sound level meter calibrator, accelerometer calibration, vibration meter calibration, charge amplifier calibration, vibration meter calibration, shock sensor calibration, cabin noise measurement of a car, noise measurement of electrical appliances, vibration measurement of electronics parts, material testing to determine sound absorption coefficients, ultrasound power calibration etc.
