The Amprobe SM-20-A Sound Level Meter has been designed to meet the
measurement requirements of safety Engineers, Health, Industrial safety
offices and quality control in various environments. It offers two types
of measurements: A weight-ing and C weight.
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-A conforms to the IEC651 Type 2,ANSI S1.4 Type 2, and
JISC1502 requirements for Sound Level Meters. Which means the SM-20-A 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. |
