If you Google "C-weighted filter" you will find the transfer functions for the filters. (www.ptpart.co.uk/noise.htm or www.cross-spectrum.com/audio/weighting.html for example). Those could then be implemented using standard LV filter VIs.

Did you ever create the vi for the A, B & C weighting filter?  I need to do the same and would be grateful if I could use your vi. 

Thank you.
