Critical bandrate scale stabilizes frequency discrimination measures across durations

Evidence

This dependence is considerably reduced if, instead of the frequency scale, the critical bandrate scale is used. At long durations (around 500 ms) the critical bandrate difference of about 0.01 Bark represents the just-noticeable difference, whereas at a duration of 10 ms the JNDF amounts on average to 0.2 Bark. — Professor Dr.-Ing.

• XREF: Links to the concept that critical band processing mediates perception — relates to discussions of auditory filters.
