Any noise cancelling apps for iPhone?

I'm sleeping at my friends house tomorrow and she can only sleep with YouTube or a tv show playing in the background whereas I can only sleep in complete silence. Ear plugs don't seem to work so does anyone know of an app that I can plug my headphones into to make it completely silent?

NONE!
LET HER WEARS A EAR PHONE TO LISTEN NOISE JUNK FOR SLEEPING. THAT AVOID THOSE NOISES BUGGING YOU AND ANYONE.
* I WOULD NOT PICK A JUNK GIRL LIKE HER SLEEP WITH NOISE, PERHAPS SHE GREW UP WITH NOISY POOR LIVING AREA.
