Sound Level Calibrators
PeakTech Prüf- und Messtechnik GmbH
For sound level measurements in extreme conditions, at high altitudes or high demands on the accuracy of the measurement results, sound level meters should be checked prior to the measurement with a sound level calibrator. Also for calibration and verification of microphones in audio technology, you need a sound level calibrator, which is designed to produce several sound pressure levels at a fixed frequency characteristic. This calibrator has two switchable calibration steps.
