What version of Premiere Elements are you using? What computer operating system is involved?
It is not clear from the translation what you want to do. Here is what I think you may be asking.
1. If you are in the Audio Mixer, just put a check mark next to the numbered audio track, Narration Track, or Soundtrack that you do not want to hear.
2. Are all the audio clips on one numbered track? If that is the case, you can right click the audio that you do not want to hear and remove the check mark next to Enable that you will see with check mark in the pop up menu.
Please consider the above. If I have not targeted your question, please give more information.
