Frequency and emotional response

In terms of pure, single frequencies, I would posit that due to the Fletcher-Munson curve, there are simply frequencies that humans are more sensitive to:

https://en.wikipedia.org/wiki/Equal-loudness_contour

Therefore it takes less energy, around, say, 3.5kHz to irritate or put someone in pain, than at, say, 100Hz. We humans are simply more attuned to these frequencies by way of evolution for whatever reason. (Theorized examples include certain ranges of frequencies being where much of the energy of babies' cries live at and so on, but we don't fully know).

The question then becomes about which sets (harmonies) and sequences (rhythms) of pitches create which emotions. And that, I'm afraid, is a much more difficult question - why DO humans find music emotional?

There is a Newman Tempo Chart, which correlates various BPM with emotional feels of music. However I've yet to see a chart that correlates vibration frequency (pitch) and emotional/psychological triggers. That would be pretty cool to have access to.
