there could be a little microphone on it , and any noise over a certain threshold um it'll pick up as a a distress signal um from you and it'll beep back and say you know oh here I am or something of this sort.
Mm-hmm. But sure surely that would have to be um sort of specific rather than above a threshold 'cause if you had a loud movie on you're likely to get it beeping back at you.
Mm-hmm.
Oh yeah , yeah , that's true.
