A variety of materials may be used for soundproof panels. The major advantage of transparent material over traditional materials in noise barriers is aesthetics. The transparent panel materials such as clear plastic or glass are an ideal way of reducing or virtually eliminating the visual impact of a noise barrier. With the use of transparent materials, the drivers' view of the roadside and the sunlight penetration to the highway would not be blocked. Korean Industrial Standards for soundproof panels have been established. But, transparent soundproof panels are not included in this standards. And, some specifications provide only a few basic characteristics for transparent soundproof panels. To develop guidelines on quality criteria for transparent soundproof panel, their mechanical properties such as wind load resistance, safety under impact, and abrasion resistance were experimentally investigated.

This study introduces abnormal noise phenomenon of steel deck plate bridge which have not been mentioned in the literature or reports. The abnormal noise occurred from the time when the girder was installed and the welding was completed. And it had continued after the bridge opened. In this study, firstly, the characteristics of abnormal noise is analyzed. Also it presents the mechanism of noise generation.
