Equal-Loudness Curves for low frequencies?

Is there information about Equal-Loudness Curves (Fletcher-Munson curves, see attatchment) below 20Hz?
I know it is difficult to speak about loudness for something you don't hear, so maybe awareness or sensitivity?

Hi,

A search on the home theater forums for 'house curve' should give you some reading for an evening. Most people use digital parametric eq to acheive this.

Sounds a bit unrealistic on music, but for film is ok..

Cheers,

Rob

btw, be prepared for some expense if you want to hit 120dB+ at 10Hz :eek: :D
