Many movie theaters provide small receivers for the hearing impaired.
Some brands use this range. I could sit outside of a theater and hear all
of the movies playing.
I useed to be able to do the same thing with a regular AM radio.
The drive-in movie theatre that was around here at the time broadcast their
movie sound over the regular AM broadcast band (with very low power) so that
you could hear the movie on your car radio (after all, some people destroy
some of the drive-in speakers).
The result was that I was able to hear the movie on a regular AM radio while at
a nearby restaurant.
