초록

In this study, the spatial distribution of heavy-weight impact sound pressure levels was investigated by field measurements using the heavy/soft impact source, which is specified as a standard heavy-weight impact source in 140-11. The results showed that the vertical and horizontal distribution of measured sound pressure levels showed a significant room mode at low frequencies. Among the existing standards for measurement of a heavy-weight impact sound, KS F 2810-2 and JIS A 1440-2 provide a good estimate of the room average sound pressure level for floating floor with respect to a low bias error and 95% confidence interval. The guideline for measurement of a heavy-weight impact source was proposed in order to complement the limitations of KS F 2810-2 and JIS A 1440-2.
