“To be clear, the black headphone target frequency response curve is the equivalent of a loudspeaker in a reference listening room with a measured response of ~ 10 dB downward slope from 20 Hz-20 kHz. Both of which are subjectively preferred and perceived as flat or neutral sounding to our ears. Or put another way, as Floyd Toole describes, accurate and preferred are synonymous. The green dotted curve is the equivalent of the in-room measured response that is flat from 20 Hz to 20 kHz, which is not the preferred response, but used as the reference point for the listeners to adjust bass and treble to their preferred response.”
