FAQ

The Bruel & Kjaer 2231 Sound Level Meter should be calibrated annually (once per year) as per standard practice for professional acoustic measuring instruments. In some regulated environments or critical applications, more frequent calibration may be required.

You should calibrate the meter:
- If the annual calibration interval has elapsed,
- If the meter is subjected to physical shock, harsh environmental conditions, or significant temperature changes,
- If measurement results appear inconsistent or deviate from reference/calibrator values,
- If required by your internal quality management or regulatory procedures,
- Or after repairs or servicing. A sound calibrator (acoustic calibrator) should also be used before and after measurements to check for significant drift; if drift is observed, formal recalibration is needed.
