No, you can't; they already come that way from the factory.
Ooooo, I like this one. Who are these people and do they have any kind of formal organization? I want to join up....
I know of no other company that can piss away 5-6 years of R&D and then claim over and over that the inferior new stuff is so great. It's mind-blowing.
Since they're attacking using high frequency sound, maybe have the machine emit some random noise in the same spectrum using its sound hardware while encrypting or decrypting or performing key generation. Wouldn't something like that jam such an attack (at least from a distance; if someone got microphones into your hardware that might be a different story)?
Now people are all neurotic about their DNA being obtained when it's the content of alchohol and drugs in their system they're checking.
And you're certain that's all that's being checked how, precisely?
I'm pretty sure you're wrong on both counts.
