Patent number: 10102840Abstract: If a thickness of a sound absorber arranged in a vehicle and clearances in the vehicle do not match and gaps are formed between the sound absorber and the respective members in the vehicle, abnormal noise due to the mutual contact of the members and noise outside the vehicle enter the vehicle interior to impair vehicle interior quietness. This is solved by a sound absorber which includes a nonwoven fabric containing 5 to 50 mass % of second fibers having a lower melting point than that of first fibers and can cause the first and second fibers to be more loosely interfaced and increase a volume of the nonwoven fabric by heating the nonwoven fabric to about the melting point of the second fibers and softening or melting the second fibers even after production.Type: GrantFiled: January 29, 2015Date of Patent: October 16, 2018Assignees: AUTONETWORKS TECHNOLOGIES, LTD., SUMITOMO WIRING SYSTEMS, LTD., SUMITOMO ELECTRIC INDUSTRIES, LTD.Inventor: Yutaka Takata
