Abstract:
1. An acoustic vibration analyzing apparatus capable of carrying out analysis of acoustic vibrations by picking up data of sounds or vibrations generated due to rotation of a plurality of rotating bodies and data of a number of revolutions of a rotating body selected from the plurality of rotating bodies when a power transmission mechanism of a vehicle having the plurality of rotating bodies operates, said acoustic vibration analyzing apparatus comprising: frequency analyzing means for calculating data of frequencies of the plurality of rotating bodies by analyzing frequencies of the data of the sounds or vibrations; order converting means for calculating orders in response to specifications of the plurality of rotating bodies based on data of frequencies of the plurality of rotating bodies; speed converting means for calculating speed of the vehicle based on data of the number of revolutions of the plurality of rotating bodies; means for displaying acoustic pressure levels acquired based on the data of the sounds or vibrations in a manner corresponding to the orders and the vehicle speed; and means for reproducing sounds having a specified order selected based on display of the displaying means.
