Again, I wonder whether that's something we know, or just something we believe.  Have there been any studies of how effective the two-tone actually is?  Particularly in noisy environments?  How does it stack up against alternatives?  And how effective is effective enough? 

Seems like the budget always runs out before actual tests are performed, which leaves us with a battle of opinions.
