Question 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?

Seems that I was a little bit to quick. I found the next curves (see attatchment) in an article about acoustic weapons .
New quest; how to get one of these lines in WinISD?

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

unless you're using a small pressure chamber as your listening environment

Everyone has their own curve which they enjoy,let alone the fact that our hearing is abit different. Even though we cant hear it,the SPL is still there,which is why you feel it.
