You will likely end up with an audible sound by using
two signals at the same time. Let's say you use 77.0
Hz and 192.8 Hz. These are unrelated but you will
still get the sum and difference frequencies coming
out, which would give you around 115 Hz and 269 Hz.
You might hear the one at 269. If you used two signals
that were much closer, you could hear a slow beat
note.
Also, depending on the kind of decoders you use, they
may not be happy seeing another sub-audible tone
present along with the desired one.
After saying this, I bet someone will come along and
tell you that it will work, and how to do it!
