    Yes, sorry, I didn’t phrase that well at all. The sound pressure is actually cancelled out, but with the hypothetical example of the jet engine, anything going wrong could double the dB level instead of cancelling, and because we’re talking milliseconds difference, it would be quite easy to go wrong in this sense.
