To pursue the fad, many young people modify their cars or motorcycles by taking off the silencer, causing a big noise when they whistle past. Whether it happens during the daytime or in the night, the noise is very annoying. Particularly when it is late at night, the annoying noise disturbs people’s sweet dreams. A lot of complaints or petition calls have been received, complaining against the big noise made by modified cars and motorcycles (with silencer taken off or other modifications) for seriously disturbing people’s sleep, while they are whistling past during the nighttime. Therefore, it is necessary to assess the effect of applying the detection camera system to in-use motor vehicles in order to enhance the execution efficiency of screening of high-noise motor vehicles and “block checks” through “excessive noise camera” technology, so as to achieve our goals of improving the living environment quality of the public, people’s health and lifestyle, and sustainability. The main achievements of this year are as follows:
1. Completed collection of the noise sources of in-use motor vehicles and related information on the noise meter.
(1) Traditionally, engine noise is the main source of noises generated by in-use motor vehicles. However, with the improvement of pavement conditions, tire noise has become another noise source when vehicles are running at high speeds. Generally speaking, when vehicles run at lower speeds and the pavement is dry, the engine noise constitutes the main portion of the overall noise. On the other hand, when vehicles run at higher speeds and the pavement is wet, the tire noise constitutes the main portion. However, the proportion of noise accounted for by each noise source varies from vehicle to vehicle.
(2) In terms of spectral features of the noise and propagation properties, the overall noise of the vehicle increases due to the increase of transmission system noise as the gear is lifted to a higher level. The spectrum of the overall noise is also related to such factors as vehicle speed, gear position, load, and vehicle type. The mid-high frequency noise increases with the decrease of gear level and increase of engine speed. With the increase of vehicle speed, the spectral curve rises, particularly at mid-high frequency bands. In terms of motor vehicle noise control, other than taking control measures at the noise source and propagation path, such as improving the engine structure and installing the exhaust muffler, noise control measures can also be taken at the receiving end, such as soundproof windows.
(3) The rationale of array microphones and application examples:
In a microphone array, dozens of microphones are usually deployed to collect sound signals simultaneously, which will be turned into “sound pictures” and “sound videos” by rear-end signal processing algorithms in order to show the location of noise sources in a real-time and intuitive manner. In terms of application examples, “NoivelCam”, an independent integrated vehicle noise tracing system designed and developed by Nanyang Technological University, has been used to monitor single-lane noise on expressways. In addition, in order to regulate illegal horning, China has adopted the sonar camera (source location) system in cities such as Shanghai, Nanjing, Shenyang, and Shenzhen to help the police deal with traffic violations of such kind with high technologies.
