A weighting vs c-weighting

C-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.

Should I use A or C weighting?

Although the A-Weighted response is used for most applications, C-Weighting is also available on many sound level meters. C Weighting is usually used for Peak measurements and also in some entertainment noise measurement, where the transmission of bass noise can be a problem.

What is a-weighted and C-weighted sound?

The C-weighted frequency looks more at the effect of low-frequency sounds on the human ear compared with the A-weighting and is essentially flat or linear between 31.5Hz and 8kHz, the two – 3dB or 'half power' points. Peak Sound Pressure Measurements are made using the C- frequency weighting.

What is the difference between dB A and dB C?

The C-weighting scale is used to measure loud sounds with approximately equal sensitivity at all frequencies, just like the human ear. Decibel measurements made with the A-weighting scale are denoted as dBA; those with the C-weighting scale as dBC.

What does C weighting represent?

What Does C-Weighting Mean? C-weighting is a type of frequency weighting that is used when measuring the amount of noise in an environment. It is primarily used for measuring noise above 100 decibels (dB).
