926 - Self-similarity analysis of the floor impact sound
Tang Y., Shibayama H., Tanaka W.
Abstract
The vibration is propagated to the downstairs room by the floor impact of the upstairs. The sound radiated in downstairs room strongly depends on the floor impact of the upstairs. JIS (Japan Industrial Standards) A 1418-1 describes the measurement method of the light-weight floor impact sound level. The floor is driven by the impact hammer. The vibration acceleration on the upstairs and the sound pressure in the downstairs room are measured. The self-similar character of the time series signal of the vibration acceleration and the sound pressure is used. By the self-similarity analysis, the acoustic characteristic of the sound wave by the floor impact is estimated. The vibro-acoustic impulse response can be calculated by using those elements.
