頻率加權網路 (Frequency Weighting Network)

Characteristics of A & C.

A weighting - The characteristic is simulated as "Human Ear Listing" response. Typical, if making the environmental sound level measurement, always select to A weighting.

C weighting - The characteristic is near the "FLAT" response. Typical, it is suitable for checking the noise of machinery (Q.C. check) & knowing the sound pressure level of the tested equipment.

快慢時間加權 Time weighting (Fast, Slow)

Fast - t= 200 ms

Slow - t = 500 ms

* "Fast" range is simulated the human ear response time.

* "Slow" range is easy to get the avg. values of vibration sound level.

* The "Fast" & "Slow" response range are designed to meet IEC 61672 class 2 requirement.
