This project was mainly to assist the EPA to grasp the results of vehicle noise inspections in various cities. In this year, a total of 1,100 inspections were conducted in various cities. A total of 2,052 vehicles were informed after on-site inspections, and the informing rate exceeded 40%. Assisted the EPA in handling public reports and police notifications. From January to November, there were 36,634 vehicle noise reports and notifications, an increase of nearly 30% over the previous year. Assisted the EPA to promote the plan to prevent the refitting of qualified vehicles, continuly.The qualified cloud database had established nearly 45,000 vehicle data. For re-modified vehicles, the arbitration department would be reported under Article 8 of the Noise Control Law. Promoted Acoustic Camera Systems law enforcement, Assisted the EPA in renting 10 Acoustic camera equipment installation locations, and assisted in handling relevant meetings to achieve promotional effects. This project completes the noise accuracy comparison test of noise measurement equipment with different institutions, and produces the proposal of quality standard that the slope between the tested system and standard equipment must be 1.2±0.05, the absolute value of the intercept (Intercept) (dB) must not exceed 10, and the correlation (r) must be greater than or equal to 0.9. This project completes the investigate of the driving noise at 6 spots of urban streets in Taiwan , and the description of the source of motor vehicle parts corresponding to different frequency ranges are carried out.
