Abstract:The sufficient frequency range to be measured for the rating of impact sound insulation of floors has been a relevant research question since the 1960's when the lower limit of the measured frequency range was set at 100 Hz. It has been long recognized that walking sounds at frequencies
lower than 100 Hz might have a significant effect on the experienced impact sound insulation of floors. Recently, it has been suggested that the frequency range to be measured for the rating of impact sound insulation should b… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
