Human Factors
'Political Reference' and other sounds and comments are constantly being transmitted on the emergency radio frequency 121.5 nonstop during a [flight].  I missed two radio calls.  I had to stop monitoring the frequency because it was causing difficulty listening on our assigned ATC frequency.  In the last few years intentional transmitting on 121.5 making goofy sounds; cat sounds; and other silly stuff has gotten really bad.  This makes the usefulness of 121.5 reduced.  I know several pilots have stopped listening on 121.5 because of the distraction.  This has been going on for a few years and seems more common in the northeast USA airspace.
B737NG First Officer reported frequent inappropriate comments on 121.5 interfered with the safe operation of the flight.
