Actual Survey on Impact Force Characteristics of Real Impact Sources Due to Falling Daily Necessities for Floor Impact Sound

Key Points

The aim is to investigate the impact force characteristics of real-life falling objects.
Conducted a survey involving 24 types of real impact sources.
Measured impact force, impact time, impulse, and frequency characteristics.
Analyzed data to identify trends related to different impact sources and locations.
Impact force characteristics vary significantly by type of impact source.
Many observed trends differ from those associated with traditional tapping machines.

Abstract

Standard impact sources such as tapping machine, tire, and rubber ball are used to evaluate floor impact sounds, but these do not necessarily cover the impact force characteristics that correspond to real life. Therefore, in this report, we conducted a survey of the impact force, impact time, impulse, and frequency characteristics caused by the drop of 24 types of real impact sources. As a result, the impact force characteristics vary depending on the type of impact source and the impact location, and many trends were found to be different from those of the tapping machine.
