That is the Focus Assist Beam. It is normal to hear some sound.

The AFAB on a 430EX is not infrared?

The OP says that the flash makes the sound when it is doing a “pre flash.”

That's the modeling light and sound which is completely normal. You must have the front button (DOF) somehow programmed as the flash modeling light. You can turn that off I'm pretty sure.
