Most acoustical measurement standards recommend calibrating such microphones annually (every 12 months). However, calibration frequency can depend on usage intensity, working environment, regulatory requirements, and quality assurance policies. For critical measurements, calibration may be needed more often (e.g., before and after a critical measurement campaign).
