Abstract

Patente de Invenção: "BARREIRA DE ISOLAMENTO ACúSTICO E PROCESSO DE FABRICAçãO DA MESMA". é proporcionada uma barreira acústica composta costurada. A barreira tem uma primeira camada não tecida (13) de fibras têxteis costuráveis primárias (13a), a camada (13) tem uma espessura entre cerca de 0,025 centímetro (0,01 polegada) e 1,27 centímetros (0,5 polegada), e uma densidade entre cerca de 0,016 e 0,16 grama por centímetro cúbico (1,0 e 10 libras por pé cúbico). Uma segunda camada de baixa densidade não tecida (15) de fibras têxteis secundárias (15a) é proporcionada, a segunda camada (15) tem uma espessura entre cerca de 0,51 centímetro (0,2 polegada) e 12,7 centímetros (5 polegadas), e uma densidade entre cerca de 0,0016 e 0,064 grama por centímetro cúbico (0,1 e 4,0 libras por pé cúbico). Uma camada de barreira acústica intermediária de alta densidade (14) é disposta entre as primeira e segunda camadas (13, 15), a camada de barreira intermediária (14) tem uma espessura entre cerca de 0,025 centímetro (0,01 polegada) e 1,27 centímetro (0,5 polegada), uma densidade de pelo menos 0,801 grama por centímetro cúbico (50 libras por pé cúbico), e a camada de barreira tem uma película substancialmente contínua de material polimérico costurável de alta densidade. Vários pontos de costura (19), formados de fibras primárias (13a), se estendem da primeira camada (13), pela camada de barreira intermediária (14), e pelo menos para a segunda camada (15).
