바닥충격음 연구현황 및 전망

Abstract

Since the last 30 years, there have been various studies conducted on different topics related to floor impact sound. In this study, the papers and proceedings presented at KSNVE (The Korean Society for Noise and Vibration Engineering) for the past 30 years are sorted as per the topics, and the results were analyzed. The main subjects of these floor impact sound papers were floor impact sound isolation system, including the resilient materials, and papers on measurement and evaluation methods and prediction. Research on the prediction of floor impact sound has been conducted since 2005. Recently, research has been conducted on improving the floor impact sound isolation performance of existing apartment buildings or remodeling houses. For the slabs of apartment buildings, establishing a method for predicting the floor impact sound is imperative. It is urgent to issue international standards for the SNQ and classification scheme of rubber ball impact sound. Furthermore, adding the rubber ball impact sound measurement method as part of international standards is necessary. It is considered that the simple measurement method of rubber ball impact sound can be useful for the investigation of basic data for the development of quality control techniques in this field.
