I'm playing with the tinnitus comms.
Here is what I know so far:
-
they do not rely on an electronic device being in proximity to me.
-
there is a carrier wave.
-
in addition to the carrier wave, up to at least 3 frequencies can be simultaneously cast
-
the frequencies can change at least as fast as about 3 seconds
Right now there is a low and high frequency being broadcast for me.
