The HS6020 sound level calibrator is used for sound pressure calibration of digital sound level meters and other acoustic measuring instruments. Its notable features are small size, light weight, low power consumption, stable performance, and easy use. Compared with the piston generator (frequency 250Hz, sound pressure level 124dB), its calibrated sound pressure level of 94dB is close to the sound pressure level measured in typical acoustic measurements; Its operating frequency is 1000Hz, and during calibration, it is independent of the weighting network used in the sound level meter (the A, B, C, and D weighting networks all have zero attenuation at 1000Hz).
