So tests using sinewaves will tell us what sinewaves we can hear. But
that may not tell us what components we can hear in more complex
sounds.

AFAIK (and I would welcome source data) while the percieved amplitude of
a component may be affected by other components,

the ability to detect a frequency (at "adequate" loudness) is pretty
much boolean.

You would need to clarify your definitions of "adequate" and "boolean" in
this context before I could comment. However FWIW have a look at some of
the pages on 'hearing' on the 'Audio Misc' site, and perhaps look at some
of the results of Oohashi and others if you are interested in this topic.
It is not clear what their results may mean (if anything!), but they are
quite intriguing as they imply that 'ultrasonic' sic? components may have
an effect in some circumstances. However the snark may be a boojum...

Slainte,

Jim
