Isolamento do ruído de impacto de pisos em baixa frequência com fontes normalizada e não normalizada

Abstract: Resumoobjetivo do presente trabalho foi avaliar o nível de pressão sonora gerado por diferentes tipos de fontes sonoras de impacto em edificações, nas frequências compreendidas entre 80 e 400 Hz, utilizando diferentes combinações de piso e material resiliente no sistema piso flutuante. Foram realizadas medições com duas fontes geradoras de ruído de impacto, sendo uma máquina de impacto normalizada modificada e uma não normalizada (pera de 5 kg). Três tipos de piso (laje em osso, cerâmico e laminado) e dois mat… Show more

“…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).…”
