SmartCal

SmartCal is a sound level calibrator manufactured in accordance with international standard IEC 60942 designed to carry out the initial adjustment and final check of the SmartdB audiodosimeter to ensure better performance and greater measurement accuracy.

The sound level calibrator is widely used as the primary reference for electroacoustic instruments designed to measure noise, such as sound level meters, frequency analyzers and audiodosimeters, through the stable generation of a sound level with known amplitude and frequency.

Sound level calibrators are built in accordance with the international standard IEC 60942, which divides calibrators into classes 0, 1 and 2, where the lower the class number, the better the accuracy, i.e. a class 1 calibrator has better accuracy than a class 2 calibrator. Class 0 calibrators are for laboratory use.
