SOUND DATA PROCESSING DEVICE AND SOUND DATA PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To process sound data including a signal sound so as to reduce noise to be caused by a mechanical device. SOLUTION: A sound data processing device includes: an operating state acquisition part 101 acquiring an operating state of the mechanical device; a sound data acquisition part 103 acquiring sound data corresponding to the acquired operating state; and a database 105 storing various kinds of operating states of the mechanical device in unit time and associated sound data as a template. The sound data processing device also includes: a database retrieval part 107 retrieving a template of the operating state nearest to the acquired operating state from the database 105, and a template subtraction part 109 subtracting sound data of the template of an operating state nearest to the acquired operating state from the acquired sound data to reduce the noise to be caused by the mechanical device.
