Dear list,

I would like to draw (for any value of loudness) the equal loudness level contour signals mentioned in ISO 226. Is there any mathematical _expression_ for generating such curves in a PC? Otherwise, what other options do you recommend for their computer simulation?

Thank you very much in advance.
