I believe you're correct Clay.  I think our ears/brain can integrate the 
overall signal, and the noise, if more or less random, will recede into 
the background.  The desired CW signal will then stand out.  I suspect 
that, were you to key noise similar to the background noise and that 
filled the receive BW, it would disappear for a listener as soon as it's 
mean amplitude fell to the background level.

This may also explain why, the more you talk, the less your teenager hears.
