Some older meters used Linear, but C-weighting has replaced that in most standards, including the European Noise at Work regulations. The C-weighted Peak measurement is usually expressed as LCpeak in dB(C).

WebC curves differ from both A and B in the fact that they filter less of the lower and higher frequencies. The filter is a much flatter shape and is used in sound measurement in especially loud and noisy environments. A weighted curves follow a 40 phon curve while C weighted follows a 100 phon curve. WebThe free app combines the best features of professional sound levels meters and noise dosimeters into one simple tool.

WebC-weighting is less severe on low frequencies than A-weighting and represents the response of the human ear to loud sounds (over 100 dB). C-weighting is more typical of machine noise and jet noise measurements than in other acoustics applications. All Class 1 sound level meters are mandated to allow for C-weighting. D WebThe declared mean A-weighted sound power level for the batch of equipment permits comparison of noise emissions between different products and permits predictions of installation or work-place noise immission levels, as described in ECMA TR/27.
