When you say 'silence' do you mean no signal at all, so if you looked at
it in a waveform editor there would be no waveform at all, or do you 
just
mean very quiet (ie a small waveform)?

What does the output of sox, with the  stat  and  stats   effects look
like for these files?   If you trim out one of the sections that you 
think
is silent, what do stat & stats say about such a section?

What do stat & stats say about one of the result file's meant-to-be 
silent
sections?

Personally rather than trying to do the whole thing in one command, I'd
suggest you try working in changing the level of just one or two of the
small files, and examine them then with stat & stats.  Then look at the
file you get if you mix those two files together, and see if you can see
what levels are changing.
