The primary calibration of acoustic and vibration transducers are well standardized and confirmed by a round-robin inter-laboratory test. Secondary calibration is also very common with traceability to primary calibration. Examples of setups for microphone and accelerometer secondary calibration are discussed regarding accuracy, frequency response testing, etc. Field check methods using reference sources and other methods like Phantom calibration are discussed regarding advantages and shortcomings.
