Conventional distortion measurements include inaudible masked components

Evidence

In order to make the reduction of information flow inaudible, it is best to use the characteristics of the human ear as an information receiver, and reduce the information flow for those events that are already inaudible. The effect of masking is a typical example. It can be introduced into the processing system in such a way that those parts masked by loud sounds are not transmitted to the receiver. — Professor Dr.-Ing. Hugo Fastl, Professor Dr.-Ing.

The comparisons between LP reproduction and the master tape were not flattering, and some non-linear distortions measured in whole percentages. It is remarkable how effective perceptual masking is in tempering the distracting effects of these distortions and surface noise. In this research we were not listening for pleasure; the music was a test signal and needed to be as close to the original master tape as possible. — Toole, Floyd E, Sound reproduction- the acoustics and…, 155 (#expands, via linked claim)
