WebSep 9, 2024 · C-weighted decibels for noise at work People often forget the need to assess the risk from any impulsive noise (very sudden short-lived noises, bangs and crashes). The C-weighting is used for this to give us the peak sound pressure for the impulsive noise that the human ear is exposed to dB (C) (or LCPeak). WebApr 5, 2024 · C-weighting matches the 100-phon equal-loudness contour, which corresponds to very loud sounds. Because of its flatter shape, C-weighting is mainly … unearthed aesthetics
