“…Impact noise has been reported in the literature as the most relevant source of complaints amongst neighbors in multi-story buildings, (Rasmussen & Rindel, 2005;Niemann & Maschke, 2004), indicating that new regulations to control the impact noise should be established (Jeon, Jeong, & Ando, 2002). In that context, the disturbance caused by audio equipment with an improved low-frequency response, electrical devices, mechanical services, and mainly lightweight construction, results in the aggravation of impact noise in residential buildings (Araújo, Paul, & Vergara, 2016;Späh et al, 2013;Hagberg, 2010). Among all those noises, human walking noise is considered the most annoying in residential buildings (Jeon, Jeong, Vorlaender, & Thaden, 2004;Jeon, Ryu, & Lee, 2010;Hagberg, 2010;Park, Lee, & Yang, 2016).…”
