The increase of economic growth has brought out the noise pollutions in city regions. To evaluate these problems, this study was investigated to assessment and analysis of noise pollutions at Cheongju area in winter and summer seasons. The noise levels were measured and analyzed at the general areas the 4 roadside areas (park, residential, commercial, and industrial area). As a result, following facts have been found. The equivalent sound levels(Leq) at general are in winter were 51.3∼78.2 dB(A) at the daytime and 41.1∼63.1 dB(A) at the nighttime And in summer there were 53.5∼77.3 dB(A) at the daytime and 41.9∼64.0 dB(A) at the nighttime, respectively. These values were higher than average value of Korea. At the roadside area, the values of Leq were 51.9∼72.8 dB(A) at the daytime, 44.3∼68.2 dB(a) at the nighttime in winter, and in summer there were 62.5∼73.1 dB(A) at the daytime and 50.4∼68.3 dB(A) at the nighttime, respectively. These values were lower than average value of Korea. The calculated traffic noise index(TNI) were 64.6∼93.6 at the daytime and 26.5∼106.6 at the nighttime in winter, In summer, there were 65.0∼90.7 at the daytime, and 32.3∼91.8 at the nighttime. The TNI values varied wide ranges at the nighttime according to traffic volumes.
