Acoustic Calibrators

An acoustic calibrator is a device which produces an acoustic pressure of defined level and frequency. In other words, anacoustic calibrator provides a template of acoustic pressure.

By using such a reference we can check the accuracy of the measurements taken by the sound level meter and adjust themif a drift error in the sensitivity is detected.
