Figure 6 Acoustic measurement according to the DIN EN 61672-1:2014-07 standard. [21] Noticed how applying the A-weighting attenuates the signal in the low-frequency region up to more than 80 dB, as compared to the Z-weighting (no filter). C-weighting is another commonly used filter, which falls in between.
