The constant sound i used was radio static
The first sound sample I created was through twisting the AKG Condenser mic around on the figure 8 polarity setting. I.e the mic is in a vertical direction and twisting it on the vertical axis.
You can hear twice in the sample where the sound cuts out, that the mic is in the middle of the figure 8 polarity.

The second example i created was by placing the AKG Condenser at a distance from the sound source. You can hear the reverberations from the room. This was done with a normal cardioid polarity.

The next example of mic technique was done using the Shure SM57. This example demonstrates that the louder the sound is, the signal of the lower frequencies are boosted within the mic. So what i did to demonstrate this was move the mic close to the sound source and back out. I used an actual song for this to show the bass boosting.

In this example I used a Shure SM58. What I did was twist the mic horizontally to demonstrate the polarity of the mic, this being cardioid. It starts off facing the sound source, then racing the opposite direction, then again back to the sound source. It also demonstrates

The final demonstration is using a PZM microphone resting the back of the plate against the sound source. You can hear the vibrations through the plate in the mic and you can hear the reverberations from the wall.

I apologise about the file sizes. I didn't have any software to change the aif into an mp3.
I will endeavor to avoid this issue in the future.
I used Protools to create these examples.
