The whole purpose of the 'synth' effect is to generate tones.  Although
you didn't specify any parameters for that effect, it has defaults, so
will have done something.

I don't know why you put 'synth' there.  The --null    (sort of dummy
input file) is described as infinite silence, so I would have thought
that

sox --null --rate 16k --bits 16 --channels 1
   "C:/Users/me/Desktop/silent19secs.wav" trim 0 19

might work.
