I like when they write what the noise is, rather than try to give it a sound through writing. Like if a girl screams, it will just be written SCREAM in the background. That way you can use your imagination. I may be wrong, but I think mangas first came up with this.
But my favorite comics ever are Conan the Barbarian, in which there is a lot of narration that describes what is going on, and noises are usually described in the narrative boxes. The only written things are dialogue. I like it this way, because when Conan swings his sword, you get a nice big image of him doing so, which is not hampered by some giant letters going SWIIIIIISH muthafucka!!! The noise the sword makes is described in the narration box, and then you get the full artwork in all its barbarous glory.
I’m a party pooper.
