Fig. 1:

Examples of automated (Békésy) audiometry showing tone level changes across trials resulting in ‘reversals’ of the direction of level change contingent on the child signalling loss or gain of audibility. To be included in the analysis sample, each child had to make at least 6 such reversals for each of four tone/ear combinations. The dotted line shows the derived pure tone threshold.
