This Amprobe digital sound level meter
has been designed for audible sound level measurements. The A weighting is for general noise sound level and the C weighting is for measuring sound level of acoustic material control in various environments (ie 94dB 1 kHz etc...). The SM-20 conforms to the IEC651 Type 2,ANSI S1.4 Type 2, and JISC1502 requirements for Sound Level Meters. Which means the SM-20 uses two different weighting filters required by the IEC 651 and ANSI S1.4 Type 2: The A-Weighting and the C Weighting audio filtering.
