The recommended calibration interval for Brüel & Kjær microphones, including the 4189-A-021, is typically once per year (annually) under normal usage conditions. However, if the microphone is used in harsh environments, subject to frequent handling, or high-stakes measurements, more frequent calibration may be required.
