Acoustic Calibrator
The acoustic calibrator is the key accessory to calibrate acoustic measurement systems. The acoustic source is defined in pressure level and in transmitting frequency, it corresponds to the current class 2 standards : NF EN 60942 : 2003 and CEI 60942 : 2003. This calibrator is designed to remain compatible with microphones of different diameters. See technical specifications.
Calibration of a sound level meter is done in pressure in the cavity of the calibrator. The sound level
meter being generally used in free field, observe the free field correction term indicated in its user
manual. It is the same in case of diffuse field using.
