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.
