【Abstract】 Vibration is strongly related with sound.In order to examine the value of sound of the gearbox efficiently,rapidly and exactly, a approach was presented which using the vibration signal of gearbox.With this approach,sound value can be obtained through synthesization of sound pressure level and modification. It is proved that this approach is practicable and reliable in practice.更多还原
