Analysis on the Vibration Transmission Characteristics of the Standard Test Building by Using Standard Impact Source

경량 및 중량 충격원에 의한 표준 실험동의 진동전달 특성 분석

The purpose of this study is to provide a fundamental data for efficient and economical reduction method and predict ion method of floor impact noise. In order to get the useful results, the measurement on the vibration transmission characteristics of standard test building with four rooms by using heavy and light-weighed impact source were carried out. In this measurement various conditions such as the change of test structure construction, the pick-up sensor location, the excitation posit ion, and the resilient material types were applied to get the vibration characteristics transmitted from excitation room to adjacent rooms.
