It depends. Some comics might benefit from sound effects to enhance the atmosphere and action, but others rely solely on the art and dialogue to engage the reader.
Well, one way is to use simple lines and shapes to represent the type and intensity of the sound. For example, for a loud explosion, you might draw jagged lines spreading out.
You can use different thicknesses of lines and varying colors to add emphasis and depth to the sound effects. Also, think about the direction and speed of the sound and show that in your drawing.
You can start by observing real-world sounds and trying to represent them visually. For example, a thunderclap might be shown as jagged lines and bold colors.
You can look for free sound effect libraries online and choose the ones that fit your story. Then, use audio editing software to incorporate them at the right moments.
One way to write sound effects in comics is to be creative with your words. For example, 'swish' for a quick movement or 'thud' for a heavy landing. And don't forget to place the words strategically within the panel to match the action they're associated with.
