The noise overcomes the clear sounds of the voice.
The victory does not equate with a hindrance put to an audible voice. It is more than this, since the noise harshly directs those who hear it into a certain state of mind excluding them from the state of talking.
Though the voices also wish to direct people to a certain state of mind, they do this by associating the desired state with the peaceful state of talking.
Simultaneously, the noise put the man under it. Even those who shout are beyond their loud cries.
When after a while we cannot explain through clear words why did we lived in a way or another, the cause is probable the fact that we acted following some noises. And even if we can remember that we acted according to our own choices, maybe our choices had a secondary value as ones which were beyond the noise.
