Abstract
A sound inspection apparatus that includes at least three microphones, a removing unit, and an estimation unit. The removing unit calculates an impulse response based on a sound pressure of a radiation sound collected via a reference microphone and a first microphone, calculates an impulse response based on the sound pressure of the radiation sound collected via the reference microphone and a second microphone, and removes a component corresponding to the vibration sound from the calculated impulse response. The intensity calculation unit calculates an intensity of the radiation sound based on the impulse response from which the vibration sound is removed, and the estimation unit estimates, based on the calculated intensity, a site where an abnormality in the inspection target object has occurred.
