Effects of the sound field characteristics of the receiving room on heavy-weight impact sound measurement generated by impact ball
- 발행 : 2006.11.16
초록
This study is a fundamental investigation for standardization of the heavy-weight floor impact measuring method by the impact ball. The distribution chrematistics of floor impact sound level and reverberation time in a receiving room of the testing building for floor impact sound were measured with variations of number and arrangement of the sound-absorbing materials. Total 8 cases were investigated. The distribution of the floor impact sound level(
