I need to know what's the difference between listen and hear.
I dont know how say these: - I listened in my computer a sound about barbershop.
or- I heard a sound about barbershop.

Great question.  

Hear - is the general thing that happened or is happening -  You heard the car driving.  I can hear your computer making noise.  

Listen - is a direct action... I am listening to music.  I am listening to your computer making noise.

I don't know how to say this:

I listened on/with my computer ....

or- I heard a sound about barbershop.

No entiendo bien lo que quieres decier con "a sound about barbershop."

You can "hear" anything.

"listen" = "hear" + ("understand" or "try to understand")

oír = hear

esuchar = listen to

This should be put in the Answers section usually, but I'll answer it here.

The difference is in intent.  If I hear something, that means that I may have been expecting it, but perhaps not.  If you here a knock on the door, and weren't expecting it, you would not say that you were listening for it.

If you listen to something, you expect to hear something.  If I listen to a CD, I have put a CD in my player and I am expecting to hear it.  If I listen to somebody, I expect that they  will say something.

If I say I hear a voice, it would give the idea that I was not listening for it and did not expect it.

I hope this helps.
