System description

The PCE-SC 09 sound level calibrator is a battery-powered wound source for direct and quick
calibration of sound level meters and other systems for noise measurement. With adaptors, it can
be placed on ½- and ¼-inch microphones. The calibration reference is 1000 Hz. This is the reference
frequency for the internationally standardised evaluation curves. This means that with this calibrator
you can calibrate sound level test equipment with A-, B-, C- or D weighting filters or with linear sound
levels. The calibration pressure is 94 ±0.3 dB (1 Pa) and 114 ±0.3 dB (10 Pa).
