FAQ

The Brüel & Kjær 4191 Microphone should be calibrated annually (every 12 months) under normal laboratory usage. However, calibration interval may vary based on regulatory requirements, use conditions, and laboratory policies.

Calibration is needed if:
- The scheduled calibration due date is reached (per your lab's calibration schedule—typically every 12 months).
- There are unexpected changes in measurement results or sensitivity shifts.
- The microphone has experienced mechanical shock, contamination, or adverse environmental conditions.
- There are requirements from standards, clients, or regulatory agencies.Most facilities maintain a calibration log or management system that will alert when the next calibration is due. Additionally, any noticeable drift in measurement compared to reference standards may also indicate a need for recalibration.
