dB(ELC) - A Proposal To Modify The dB(A)

The dB(A) is a widely used measure for loudness. In contrast to the dB(A), the proposed dB(ELC) (Equal Loudness Contours) uses four different weighting filters. This kind of dynamic loudness-contour adaption corresponds with the unequal weighting of different frequency components at variable sound pressure levels.

Plone makes heavy use of CSS, which means it is accessible to any internet browser, but the design needs a standards-compliant browser to look like we intended it. Just so you know ;)
