Public library is the most well-used cultural infrastructure, life-long learning space, and social facility within local community. In order to respond to the multi-purpose identities, space structure of many public libraries is changed or reconstructed to open-concept, multi-functional and interconnected areas. Accordingly, the noise issue in public libraries has emerged as one of key environmental parameters and noise management is bound to be considered as a scale for determining whether a user-friendly library. This study measured the noise level of the public libraries in Daegu city, analyzed measurement results on the basis of national and international standards, and suggested the various reduction plans.

Highway traffic noise is the one of the most frequent pollutant source of environmental claims in Korea for the last 10 years. For abating the noise from the highways, characteristics of highway noise source should be investigated and identified before performing the abatements. Highway noises are affected by traffic volume, vehicle types and speed, tyre and pavement types. In this study, highway noises which measured from different pavements have been analyzed and compared. Especially, the noise from the asphalt concrete pavement, cement concrete pavement and low-noise pavement have been measured simultaneously at the same traffic condition and compared each other. Hopefully, the data of the study may be used for abating highway noise and further studies.
