The noise by the construction activities is one of the main issues in Korea. To prevent the noise from construction site, construction company installs temporary noise barriers along the construction site boundary. Normally sound insulation performance ($R_w$) of the temporary noise barriers made by metal or plastic is between 18 and 31 dB and metallic noise barriers are around 5 dB higher than plastic noise barriers. Sound absorption performance (NRC) of the temporary noise barriers are between 0.20 and 0.59 so it's difficult to characterize their acoustic performance. In this study, it has founded that sound insulation performance of the temporary noise barrier has been improved about 3dB by stick the high density acoustic sheet and insertion loss of noise barrier is getting increased as the source and receiver approached the temporary noise barriers.

Noise and vibration occurs during construction intermittently, but with the most arise complaints. There is a need to efficiently manage the construction noise and vibration problems because in case a residential facility that requires calmness around the construction site adversely affects the living conditions of nearby residents. The ministry of environment has mandating the installation of soundproofing facilities for the management of construction noise. In order to enforce a particular construction, the mandatory install with soundproofing facilities before the start of construction, and after construction. However, Installation guide of soundproofing facilities for construction sites were not considered affected areas by noise and there is no provision of performance evaluation for soundproofing facilities. In this study, investigated the status and problems of the installation guide for soundproofing facilities in construction sites, we propose an efficient installation guide of soundproofing facilities for the reduction construction noise.

The research is an objective which prevents a construction noise by developing prediction program on utility, helps comprehension of construction noise by case study. The program developed with Visual Basic of the Excel Logic. The standard noise is a data with report of the construction machine (National Institute of Environmental Research), construction noise of sound pressure level applied the distance decrease of the point source. The decrease effect of the barrier noise wall used the data of 5, 10, 15, 20dB where the diffraction is reflected. used a program, case study is suggested Prevention method to prevent noise of construction site.

A construction noise is the main reason for people's petition among the pollution. The purpose of this study is to develop the noise prediction program to see the level of the noise on the construction site more accurately. For this purpose, the database of the power level on the various equipments was made. The noise reduction by distance and the noise reduction by diffraction of barrier were mainly considered and calculated. The simple noise prediction program will provide the information about proper height and length of the potable barrier which satisfies noise criteria of the construction sites from a construction planning stage. To investigate the reliability of this program, the predicted data was compared with the measured data. An average of difference between measured data and predicted data is 1.3 dB(A) and a coefficient of correlation is about 0.95.

With the improvement of living quality, people's desire for quiet living environment keeps increasing. In particular, complaints about the noise emission by constrcution equipments around residential areas take most part of the noise related complaints. In this study, noise marking obligation system for the high noise construction equipment have been proposed to reduce the noise level and protect the well-being of citizens. For this purpose, construction equipment used in the country were surveyed and compared with that of the European Directive/2000/14/EC. As results, 20 kinds of construction equipment were proposed for the obligated noise marking, while 13 kinds of construction equipment were proposed for the equipment subject to permissible noise level, thus the obligated noise marking and certification.

Recently, in construction field, large construction equipment are used to reduce the construction schedule and labor cost. Therefore, construction vibration has caused much annoyance and that induced from operating of large construction equipment, has become a major problem for a number of dwellers in nearby construction field and it has become a very serious issue in our living environment. In this point, this study attempts to survey on the characteristics of piling vibration by oil pressure method in construction field. And this study intends to get the basic data to establish a standard about construction vibration.

This paper analysed the effect on Heunginjimun of ground vibrations due to C.I.P. works during Heunginjimun restoration period. Vibration criteria and laws for historic structures was investigated. The vibration was measured under test construction in the field, analysed and evaluated. Because the ground vibration exceeded the vibration criteria, the restoration construction could not be go along. But as vibration was transferred to the upper structures, it was confirmed that vibration levels declined, because of differences between natural and forced frequencies. If the natural frequencies database of historic structures are established, it will help with management and preservation of cultural properties by an environmental vibration effects evaluation.

3-D noise map of Mugue Dong of the Ulsan City has been constructed. Comparing with the measured noise level, the predicted noise level has been confirmed for its accuracy. Correction factors for better prediction result using the constructed noise map have been investigated proving that its method is useful. The procedure of noise map construction method has also been introduced using RLS-90, Cadna A.

Community noise has been serious social issues in Korea. The community noise concerns on traffic, construction, factory, and apartment complex noise. In traffic noise, road, railway, airport sectors are included. This paper summerizes the final report prepared for MOE in 2005 by authors. The new policy will be enforced beginning in 2006 with 5 year schedule. Details on the policy will be demonstrated at the presentation.
