WebAs far as I am aware, the main target response curves that are used by companies today are the open-ear diffuse-field response curve, and the Harman target response curve. While I'd love to read the papers linking to how researchers came to these curves, I can't afford them (most are hosted on the AES website which requires membership or a flat fee).

Research characterizing the human hearing range generated an areal map of auditory response as shown in Figure 1. The shape of the minimum audibility curve tells us something about the frequency response of the ear at low sound pressure levels. grant macewan facultyAn equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours. By definition, two sine waves of differing frequencies are said to have equal-loudness level measured in phons if they are perceived as equally loud by the average young person with… grant macewan college programsHearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours.
