The idea of a (random) noise generator located next to the microphone is
of more general application since it allows your phone to continue to
operate to receive calls. 

Placing your phone in an RF shielding bag or removing the batteries to
prevent your phone being used as a roving bug has side effects!

I would hope that such a noise source could be placed in a special
carrying pouch for the phone which would also serve to make the noise
source inaudible outside of the pouch.

But if you genuinely have grounds for believing that the Watchers are
watching you then worrying about a bugged mobile phone is probably the
least of your problems. In this case there are also likley to be
tracking devices, audio and video bugs, etc, in your car, your office
and in your house in light swithes and sockets, the TV, etc!!
   
Those of us who live blameless, if boring lives, have nothing to worry
about have we.  :-}
