Measurement accuracy on fixtures directly predicts agreement with human listeners

Evidence

The ideal headphone measurement is accurate, reproducible and agrees with measurements made on an average human: the closer they match, the higher the correlations will be between the objective and subjective measurements. However, there are many errors that prevent a perfect match including the accuracy of the test fixture, how the headphone couples to it, and differences in how the headphone couples to a human. — Toole, Floyd E, Sound reproduction- the acoustics and…, 1715
