The invention discloses a method and device for acquiring event change information. The method includes: acquiring a first mapping relation set, wherein the first mapping relation set is used for describing the corresponding relation between each even identification in a first project corresponding to a currently-updated sound resource file and an event verification value, and the event verification value is obtained by performing verification operation on multiple hierarchy parameters of each event according to a preset verification algorithm; comparing the first mapping relation set with a pre-stored second mapping relation set to obtain the event change information. By the method, the technical problem that whenever a sound effect producer iteratively updates an event and after the sound effect producer packages and exports the sound resource file and submits the updated file, testing staff cannot acquire the event updating condition from the submitted updated sound resource file in the prior art is solved.
