The frequency-selectivity of loudness perception was first shown in the 1930s, when Fletcher and Munson published a set of curves showing the ear's sensitivity to loudness compared to frequency. These equal-loudness curves, as shown in the question above, are now known as Fletcher-Munson equal-loudness contours. In general, the smaller the ear canal, the more amplification in the higher frequencies. Infants and small children have tiny ear canals and are therefore typically more bothered by loud high frequency sounds.
