... I have worked on masking along a new physiologic route for
several years and am convinced it is an interactive consequence
occuring DURING the interaction.

... Masking is a "swamping" interaction and, as such, requires
all signal elements to be present during the same time period.
... An effect succeeding a stimulus (not during the stimulus)
reveals a different process and may, in fact, be an adaptation,
possibly a consequence of middle ear (AGC?) time constants:
I agree with this masking qualification.
