| 摘要 |
The present invention relates to an apparatus for generating evidence of a sound signal with respect to the operation perception of a vehicle braking device, which generates sound signals having a specific sound pressure close to the minimum audible value of specific frequency when a driver operates a vehicle braking device to record the sound signals together with the internal and external sounds of a vehicle and then play the internal and external sounds of the vehicle after enabling the driver to easily listen the sound signals by increasing the relative intensity and sound pressure of the specific frequency, thereby comparing and analyzing whether the braking device is operated as time passes. Therefore, the present invention proves whether an accident is due to the fault of the driver. |
