  • To install and operate the Automatic Noise Monitoring Networks reasonably, which able to monitoring environmental noise continually, is an important issue for making decision to urban environment. Noise level is determined by regional environmental factors, that affected by complex urban environment. Therefore, accurate measurement of environmental noise level has top priority to establish and promote appropriate environmental policies. Currently, Automatic Noise Monitoring System is installed for grasping the environmental noise level and preparing basic data for constructing noise-reduction policies. However, this measurement data is recognized not to be able to reflect a sensory noise. The main reason is the lack of reliable measurement data and unreasonable installation site. The main point of this research ought to be the analysis of installed site of noise monitoring system in Busan.

  • A noise reduction policy can be more effectively made when automatic environmental noise measurement system is set up. However, the local characteristic of noise pollution requires a lot of measurement points. This study considers that automatic environmental noise measurement system connects with automatic air pollution measurement system and noise map. The measurement points of traffic volume by the National Police Agency and the Ministry of Construction and Transportation are investigated to use at drawing the road traffic noise map. Finally, the effective application method of the environmental noise measurement vehicle is discussed.

  • The purpose of this study is to present a guideline to design a short-term manual measurement of environmental noise level, which is more economical and flexible, but less representative than long-term automatic measurement. The proposed guideline can provide the number of measurement times and the length of measurement term required to secure the extent of the representativeness. The data was collected at 4 sites located in Seoul and at 4 sites located outside of Seoul. The probabilities for five-minute equivalent noise levels, Leq, 5min, to stay in an error range from the quarterly representative noise level were used to evaluate sampling techniques. The probability analysis of the daytime period showed that the noise levels measured between 10 am and 2 pm and between 9 pm and 10 pm have the probabilities higher than 60 %. On the other hand, even for the same length of total measurement time, increasing the number of random samplings results in higher probabilities than increasing the length of measurement term.
