Since the noise regulation of land-based transportation takes effect, all the noise complaints that did not meet the noise regulation, the office in charge should take action to propose mitigation plan to the noise problem. The noise mitigation proposal should include the modeling of the acoustic environment at the site of noise complaint. Besides clarifying the main noise source, the acoustic model will allow mitigation plans to be evaluated before actual construction. Therefore the main purpose of this project is to:
1.prepare the workflow of the pier review for the acoustic model.
2.prepare the related document for the pier review.
3.regulate the document needed for the pier review.
4.propose regulation for the pier review.
5.setting up method for measuring the sound power level of the transportation systems.
6.review at least 15 cases of mitigation proposal.
