The present invention provides an acoustic vibration analyzing apparatus
for carrying out acoustic vibration analysis by picking up data of sounds
generated due to rotation of a plurality of gears and data of the number
of revolutions of a gear selected from a plurality of gears when a
transmission of a vehicle having the plurality of gears operates. The
acoustic vibration analyzing apparatus comprises an acoustic vibration
calculation portion for analyzing acoustic data in terms of frequency, an
order calculation portion for calculating an order in compliance with the
specifications of a plurality of gears, a speed calculation portion for
calculating the speed of a vehicle, and a display unit for displaying
acoustic pressure levels with the order and vehicle speed associated
therewith.
