Abstract

The impact source (tire in JIS 1418-2:2000) currently used to evaluate heavy-weight floor impact sound insulation seems to have too much impact force for the wood frame construction. Moreover, it is not well confirmed that what kind of impact source and physical index are reasonable to evaluate the insulation performance in the wood frame construction. This pilot study confirmed the relation between subjective ratings and physical indices of heavy-weight floor impact sound recorded by various impact sources in mock-up of wood frame construction. The recorded floor impact sound level showed that rubber ball sound at 10 cm showed similar sound level and spectrum to adult's jumping sound. The subjective tests found that LiFavg,Fmax (arithmetic means of octave band level, 63-1k Hz) was best correlated with annoyance. Floor impact sound with dominant spectral component in high frequency range showed larger annoyance. Result of this study suggests that weaker impact source is needed and higher frequency band should be given attention to physical rating index and reduction of annoyance by floor impact sound.
