There is disclosed a sound source separating apparatus (100) including: a sound pressure detecting unit which detects a sound pressure in which fluid sound generated due to fluctuations in fluid pressure and oscillation sound generated due to oscillation of a solid are mixed; an oscillation detecting unit (2) which detects oscillation of the solid; and a sound source separating unit (3) which separates the sound pressure detected by the sound pressure detecting unit into a fluid sound component and an oscillation sound component for output by using the sound pressure detected by the sound pressure detecting unit and the oscillation detected by the oscillation detecting unit (2). By separating into the fluid sound and the oscillation sound, it is possible to effectively and rapidly implement oscillation and noise control and reduce a development period of a noise-free product.
