Noise Dosimeter Calibration

Accredited calibration

When a noise dose meter is used to measure results for public purposes or possible trials, calibration must be accredited. Country requirements state how often calibration must be performed. Brüel & Kjær can provide these types of accreditations for Brüel & Kjær noise dose meters:

• DANAK (English certificate)
• A2LA (English certificate)
• ENAC (Spanish certificate)
• Inmetro, Brazil (Portuguese certificate)

Initial calibration

To start the accredited calibration history from day one, we recommend that you take advantage of our accredited-calibration services when you purchase your new noise dose meter.

Re-calibration

For noise dose meters, we recommend regular calibration to provide you with an unbroken calibration history to use as a reference, either for internal requirements, or at the request of your customers.
