In general, reliable measurement competences of sound and vibration are needed in development and quality assurance for product. Especially in industrial field, such as automotive and aero-space industry, high performance measuring platform and efficient calibration procedure for keeping good measurement are strongly requested, in which is not allowing to have down time due to failure of measuring instruments. So, this article describe following technologies: transducer electronic data sheet (TEDS), extremely wide dynamic range (Dyn-X), response equalization of transducer (REq-X), charge injected calibration (CIC), and vibration transducer calibration system based on improved FFT method (calibration by substitution).
