In listening tests, the instrument of measurement is the human ears belonging to the test subjects. Given a common analog/acoustic playback signal delivered over speakers or headphones, the received and experienced sound will vary among the listeners according to their own unique physiological capacities (and damage).
I've never seen a study done in which the individual subjects' hearing was tested and used in the data analysis following data collection. If not, the instrument of measurement is not being calibrated. The most I've seen is simple notations to the effect that "Experienced and novice listener groups were tested separately" or "Trained and Untrained listeners' results are charted in Figure 3").
It's hard enough getting the budget and equipment together for sound tests at all, this would add yet another layer of expense and resource needs. But if the point is to understand what the listener's judgment and possibly interpretation is, it's important to know the capacities of the [physiological] equipment they're measuring with.
