For different generations, there is already different audible signals for 
emergency messages.

G.I or Silent generation: the single 1 kHz tone and tuning to 640 or 1240.

Baby-boomers: the dual-tone attention signal for 30 seconds and a long 
required testing script which many can still recite ("This is a Test. This 
is only a test...")

Generation X: the triple duck farts signaling a shorter testing script

Millenials: Wireless Emergency Alert signal (an on/off cycle of dual-tone) 
on mobile phones signaling an Amber alert

The Good Old Days weren't really that good, they were just the old days.
