My understanding was that greater vocal effort leads to mostly more low-frequency energy.

Energy around 2-5 kHz is quite high for speech; hard to imagine the spectral peak moving that high, even if the effort->lows thing doesn't apply to screams.

Dear collective wisdom,

I recall reading somewhere (long ago) that most human screams exhibit a spectral peak in the 3 kHz region (more broadly, 2-5 kHz) coinciding with the threshold dip due to the ear canal resonance. The implication is that screams are co-adapted to the most sensitive region of human hearing.

Can anyone point me to a suitable reference? Even literature reporting power spectrum data for human screams would be useful.
