摘要

During operation of the transmission of a car having a plurality of gears, a sound/vibration analysis device picks data on sound occurring from the rotation of the gears and data on the rotational speed of a gear selected ou t of the gears, and makes a sound/vibration analysis. The device comprises a sound/vibration calculation section for making a frequency analysis of sound data, an order calculation section for calculating an order in accordance wi th gear specifications, a velocity calculation section for calculating the car velocity, and a display for displaying a sound pressure level with the order and the car velocity associated.
