SOUND VIBRATION ANALYZER, SOUND VIBRATION ANALYZING METHOD, COMPUTER-READABLE RECORDING MEDIUM WITH PROGRAM FOR SOUND VIBRATION ANALYSIS RECORDED, AND PROGRAM FOR ANALYZING SOUND VIBRATION

摘要

PPROBLEM TO BE SOLVED: To provide an analyzer capable of discriminating surely a generation factor of a sound and a generation point thereof. PSOLUTION: Orders of the sound are computed on the basis of a frequency and a pulse signal data of the sound obtained by frequency-analyzing a sound data by reading the sound data generated from gears of a transmission of an automobile, and reading the pulse signal data of the specified gear in. On the other hand, a sound pressure level of the sound and a vehicle speed of the automobile are found to display order graphs 93, 95 indicating a change of the order with respect to the vehicle speed on a screen. Plots of the order graphs 93, 95 are color-coded in response to sound pressure levels. The sound having the special order is reproduced from a speaker by an operation of a regeneration setting area 97. An original sound, only a sound having the specified order, and a sound in which the sound having the specified order is removed from the original sound are able to be selected in the reproduced sound.
