ンジン等の音響インテンシテイ測定装置。 An engine or the like comprising a sound collection device 1 that collects sound in a nearby sound field of a noise generator 3 such as an engine, and a traverse device 2 that supports this sound collection device 1 and moves it to a predetermined nearby sound field. The sound intensity measuring device includes a distance measuring device 4 that measures the distance between the noise generating body 3 and the sound collecting device 1 in a target near-field sound field, and a distance measuring device 4 that measures the distance between the noise generating body 3 and the sound collecting device 1 in a target near-field sound field, and a distance measuring device 4 that measures the distance between the noise generating body 3 and the sound collecting device 1 in a target nearby sound field, and a distance measuring device 4 that measures the distance between the noise generating body 3 and the sound collecting device 1 in a target nearby sound field, and 3 and a control device 5 for controlling the traverse device 2 so that the distance between the sound collecting device 1 and the sound collecting device 1 is constant.
