How good of yeller are you? 

I mean, if you were giving a speech in a  really big room that was crowded with people, could you yell your speech  loud enough to make sure that even the people in the back could hear  what you were saying? If you are like me, you might be able to do this  for a while, but you sure could not do it for an entire speech. That’s why we need help when we find ourselves in situations like this. This is when the microphone comes in to play.  However, it turns out that using a microphone is not as simple as it  might initially appear. 

There is a right way to go about doing this and a  wrong way.
