Patent number: 11705098Abstract: The sound absorbing material according to the present invention is formed by laminating a porous sound absorber and two or more sheets of a nonwoven fabric one on another. The nonwoven fabric has a plurality of drawn filaments arranged and oriented in one direction. The mode value of the diameter distribution of the plurality of filaments is in the range of 1 to 4 ?m. The grammage of the nonwoven fabric is in the range of 5 to 40 g/m2. The sound absorbing material according to the present invention provides high sound absorption performance in a predetermined low frequency band of 6000 Hz or less, and still remains light in weight and flexible enough and easy enough to handle to be substantially comparable to the porous sound absorber.Type: GrantFiled: June 15, 2018Date of Patent: July 18, 2023Inventors: Kunihiko Ibayashi, Hiroaki Konishi, Muneyuki Shiina, Masahiro Wakayama
