| Summary: | 碩士 === 國立臺灣大學 === 造船工程學系 === 86 === Recently, many bigger cities in Taiwan are much more highly
developing and also our government will hopefully build Taiwan
to be a center of management and trans-portation in Asia-Pacific
area. Therefore due to the fact as described, the high speed
railway in Taiwan will be constructed with BOT style in recent
years. To be expectedly, it will brings human peoples in Taiwan
trafic most convenience and also will creates deep influence on
both indusrial and commercial business in Taiwan. Because very
high speed of HSR, it becomes very conveninet.Contrarily it will
also bring human more noisy environment. Many countries having
HSR had spent a lot of peoples and finance to protect the noise
produced by High Speed Railway among them.This thesis is to
study the noise produced by the High Speed Railway in operation
after. its being constructed in Taiwan. Also using SOUNDPLAN,
this thesis is to predict both the noise generated by the high
speed railway in Taiwan and the insertion loss provided by the
acoustic barrier adopted.In addition, the result of the above
insertion loss is also to compare with that obtained from the
actual measurement, the calculations by using both diffraction
theory and SAS regression model . Finally, this study is very
hopefully to greatly reduce the high speed railway noise
economically when we use the result as obtained to match with
that obtained from the insertion loss experiment of the sound
barrier with varying the angle of its upper panel.
