Use of Impact Ball for Evaluation of Floor Impact Sound
층간소음 평가를 위한 임팩트 볼의 활용
- Published : 2005.11.01
Abstract
To use the impact ball as a new standard floor impact source, the objective and subjective properties of the impact bali were investigated. The results showed that not only the objective properties of the impact ball such as the Impact force exposure level, mechanical impedance but also the psychological parameters were more similar to those of the human impact than the bang machine. In addition, most of the subjects chose the impact bail sound as the most similar sound to the human impact sound in the auditory experiment.
