Report Errors
This study investigated the relationship between dynamic stiffness, thickness, and heavy-weight floor-impact sound level for EPS resilient materials with 10 MN/m3 ~ 30 MN/m3 dynamic stiffness and 10 mm ~ 30 mm thickness. As a result, the single-number quantity (SNQ) with a bang machine was 52 dB ~ 57 dB, SNQ with rubber ball at 1.0 m height was 48 dB ~ 52 dB, and SNQ with rubber ball at 0.3 m was 43 dB ~ 48 dB. The relationship between dynamic stiffness and SNQ with bang machine was a negative correlation, and that with a rubber ball was a positive correlation. The floor impact sound level at 63 Hz showed a negative correlation with dynamic stiffness, and those at 125 Hz and 250 Hz showed positive correlations for all impact sources. The thickness of EPS resilient materials was negatively correlated with floor-impact sound level over 125 Hz for all impact sources. In addition, a design method of EPS resilient materials is discussed using a contour map of floor-impact sound level in terms of thickness and dynamic stiffness.
