Help adding an hour of no noise to my track

I have tried looking around but apparently that is too specific. I have a 14 second track telling myself about how I am dreaming so I can lucid dream tonight. I want this to loop every hour on my iPod, but I need help adding that blank hour. Can someone do an in-depth guide for a noob?

Try using “Generate > Silence” http://manual.audacityteam.org/o/man/generate_menu.html#silence
