Strong condensation can suppress masking below the quiet threshold

Evidence

It is interesting to note that in the region of the condensation maximum, which is in the middle of the pattern, masked threshold becomes even lower than the threshold in quiet indicated by the arrow on the right ordinate of Fig. 4.32c. — Professor Dr.-Ing.
