Acoustical Characteristics of the Floor Impact Sound Transmitted to the Upper and Lower Floors by a Rubber Ball in Apartment: Effect of Excitation, Receiving Position, and Rubber Ball Dropping Height
Transactions of the Korean Society for Noise and Vibration Engineering(2023)
Abstract
This study was conducted to investigate the propagation characteristics of the floor impact sound transmitted from the household where the noise of the apartment building occurred to not only the floor directly below but also to other neighboring households. The floor impact sound of a rubber ball was measured on three upper and lower floors based on the excitation floor. The single-number quantity (L
