WebWhat humans are physically capable of hearing is represented by the A-Weighting curve. Acoustic sound contains more lower and higher frequencies than humans perceive. The C-Weighting curve represents … WebThe following figure shows the unweighted sound pressure level of a sound which is at 0 dB SPL for 10 seconds, sharply rises to 40 dB SPL for 10 seconds, then falls to 0 dB again. When weighted, it can be seen that it takes time for the sound pressure level to ‘react’ to changes when compared to the unweighted sound pressure level.

Web‘C’ Weighting ‘C’ weighting gives much more emphasis to low frequency sounds than the ‘A’ weighting response and is essentially flat or linear between 31,5Hz and 8kHz, the two … Web4 Jan 2013 · Your computer is probably putting out more sound at these comparatively higher frequency than it is at the lower frequencies (which the 'C' weighting includes). FYI, when calibrating monitors, 'C' weighting is used. It's all for what purpose you're measuring, as to which weighting you use. Each will tell a different part of the story.

WebC-A also plays a role in sound exposure and noise pollution applications. A Weighted SPL is generally a good indicator for noise-induced hearing loss, although extremely high levels of low frequency energy can be damaging, so if a mix has a high C-A value, that is a good indicator that additional attention should be paid to LF exposure.
