Setting of the frequency weighting characteristics

Setting of the frequency weighting characteristics

There are three kinds of frequency weighting, such as A, C and FLAT. Select it by the panel switch [A/C/FLAT] according to your measurement purpose.

 

The frequency weighting according to the measurement purpose

Refer the following table to select the frequency weighting according to measurement application or purpose.

 

A-weighting

·Applicable to general sound measurement

C-weighting

·Measures approximated sound pressure level in sound measurement

·Measures criterion of magnitude of low-frequency components in comparison with A-weighted sound pressure level measurement value

·When records AC output

FLAT

·Measures a pressure level in acoustic measurement

 

Selecting the frequency weighting

Each time you press the panel switch [A/C/FLAT] the weighting changes as follows; A-weighting, C-weighting, FLAT, A-weighting,…
