A vibration noise reduction analysis method for automotive panel parts acquires optimal distribution of beads to be provided in an automotive panel part to reduce noise caused by vibration of the panel part. The vibration noise reduction analysis method is executed by a computer, and includes: an automotive body analysis model acquiring step; an analysis condition setting step; a single-bead arranged area setting step; a bead parameter distribution acquiring step; an equivalent radiated power (ERP) reacquisition step; a bead parameter distribution acquisition step on a minimum ERP in bead-arranged area; and an optimal bead distribution determination step. The bead parameter distribution acquiring step includes: a bead parameter selection step; a bead parameter distribution analysis model generation step; and a bead parameter design variable distribution analysis step.
