WebPeak Sound Pressure Measurements are made using the C- frequency weighting. Measurements are typically displayed as dB (C) or dBC. Or for example as LCeq, LCPeak, LCE – where the C shows the C-weighting. Calibration – The process of measuring to determine the accuracy of your measurement chain. WebApr 13, 2024 · If a non-impulsive sound has the potential of exceeding the peak sound pressure level thresholds associated with impulsive sounds, these thresholds are recommended for consideration. Note: Peak sound pressure level (L0-pk) has a reference value of 1 [mu]Pa, and weighted cumulative sound exposure level (LE,) has a reference …
