| Abstract |
This research, a preliminary study to develop Active Noise Barrier System as an alternative Reduction of Road Traffic Noise, indicates surveys and analysis of professional groups' attitudes and necessities based on previous researches and current technical users. Examinations with expert surveys are carried out to evaluate the level of technology, the possibilities of success, and the needs of the proposed system, listing core skills to establish Noise Barrier System and determining the prior knowledge for this research. Upon receiving requests from a domestic ANC level, the elevation is accounted as same as around 60%-70% of developed countries in most fields. However, the result of domestic strategies field indicates that ANC and Green Sound Barrier are the most effective. Also, according to the assesment about the possibilities of success on each technology, Active Noise Barrier System is highly evaluated, considering both developed Information Technology (IT) with its infra in Korea and bright potentials on accomplishment of ANC system including H/W and S/W. |
