It's my understanding that a sonic boom is the doppler effect taken to the extreme, with a sound emitting object traveling at the speed of sound, your building the ultimate constructive wave.
I want to know, if you were traveling at Mach 1.5, why doesn't the sound you're generating cancel itself out? (in layman's terms)
More precisely, if you understood how the frequency of the sound generated by your aircraft varied at different speeds as it's travelling, why can't you:
a) choose to travel at a speed that would destroy the sound wave produced?
b) deliberately place the elements of your design that cause drag (and hence, noise) offset by half the wavelength?
Or at least I assume you can't because it still takes 8 hours to fly to America from the UK, 50 years after Concorde was invented =P.
Cheers,
