speakers idiots!!
speakers
So you can hear sound from the computer.
because
the volume
As far as I can tell it lets you hear the sounds you computer produces. Personal experience makes me think that (when I was without one I couldn't hear anything), but I could be completely wrong. Just trying to help. :)
sound card
Sound card configued to either speakers, headphones or to a midi device
Sounds can be muffled when something intercepts the sound wave (lets say a blanket) and the sound waves can only get through a little bit. You can't hear the sound clearly but can still hear it, so it is muffled!
they let the sound out so u can hear music or sound
sound card/sound driver, Speakers/earphones
We can't hear it from here.
Sound is processed in the sound card of the computer. It then sends signals to the speakers. The speakers vibrate and make the actual sounds that you hear.
