Is that the reason why speakers make that loud, annoying noise in the loudspeaker? If not, then WHAT CAUSES THE NOISE?

There are noises coming out of a speaker that nobody can hear. Holding a microphone in front of the speaker amplifies these noises. They come back out the speaker. Holding a microphone in front of the speaker amplifies these noises. They come back out the speaker. This creates an infinite loop of sound going from the speaker to the microphone and back to the speaker, which is what causes the high pitched squeal known as 'feedback'.

Positive feedback, any slight noise is picked up by the mic and fed to the speaker which again is picked up by the mic and so on.

The sound goes in the mic.
The sound comes out of the speaker.
The sound from the speaker goes back into the mic.
Now it comes out again, but louder.
The cycle keeps repeating until the volume is maxed out.

It's called FEEDBACK, too many electronics in too close of a space.
