Figure 3a shows the relation between auditory acuity (JND) and the distance between the average spectral means of /s/ and /J/.
Academic text (2011) -
The speakers' auditory acuity was also measured using an adaptive staircase (JND) task.
Academic text (2011) -
Looking at individual speakers, one can see that there are two speakers with very low JNDs who, however, do not have a clear motor equivalence pattern (AF1 and CM1).
Academic text (2011) -
For the estimation of the speaker's JND parameter, the most stable sequence of trials was chosen (i.e., a sequence with only small oscillations around a mean).
Academic text (2011) -
In a hearing test, the jnd is used to determine the smallest change in volume that a listener can detect.

Etymology
Jnd is a short form of just noticeable difference, a phrase that literally means a change you can 'notice' that is 'just' big enough to be seen or heard. So a jnd is the smallest change in sound, light, or touch that people can usually notice.
