Noise cancellation microphone

Hi.
Is there anyway to be really sure if the noise cancellation mic is working? I mean, like an app that test the hardware or something like that..
I'm asking this, beacuase, for exaple I tried to make a video with background loud music and me talking at the same time. I was expecting the music to be filtered but that didn't happened. Maybe It's the Camara app that doesn't use the noise cancellation feature, but I'm not sure.
Please, I want some opinions!

Ok, but let's suppose I'm calling someone and there is loud noise in the background, is it supposed that the person I'm talking to should just hear my voice? Or is it possible that the person listens "some" noise than just my voice?

"
While most phones have only one microphone, iPhone 4 has two. The main mic, located on the bottom next to the dock connector, is for phone calls, voice commands, and memos. The second mic, built into the top near the headphone jack, is for FaceTime calls and for making your phone calls better. It works with the main mic to suppress unwanted and distracting background sounds, such as music and loud conversations. This dual-mic noise suppression helps make every conversation a quiet one."

It is not state of the art recording/motion picture industry equipment. It simply improves the quality over the one mic.

Exactly. Don't expect to be able to check in with your parents or girlfriend from a loud party, and have them think that you're in the library. It just helps cancel out some of the ambient noise.
