Yes, that's what I thought Lauren. Issues like that do date thrillers.

I have been looking it up and it isn't easy to do even today. It is difficult to triangulate acoustic signals in the sound field because the human vocal and auditory range are limited. There are animals that can do it (bats, whales and dolphins have echolocation). It was used in WW1 to try and track aircraft, but it was not very effective and once radar was developed it became obsolete.


Yes, I would have thought so too. I think it's easier to hack into a visual feed than an audio.
Thanks for researching, Lauren. I didn’t know the answer but thought it should have been addressed in the story. It appeared that it had only short range capability but that was never explained.


I thought so too. Listening in on audio when you know the location is relatively simple (think of cops or FBI agents listening in on mob hangouts), but finding the source of the sound when it is unknown is very difficult and expensive although not impossible.
