Sound-absorbing and sound insulation soft composite materials of textile for noise reduction

Soft composite materials of sound-absorbing and sound insulation textiles as a new-type noise reduction materials have drawn much attention because they can provide wider sound absorption band than traditional textiles and lighter, more softer, more breathable and easier to process than traditional noise reduction materials. Consequently, significant research interest in the field of noise control has been directed into the research of polymer composites based on textile materials. In this paper, a review of the research progress of soft textiles of sound-absorbing and sound insulation materils from three aspects of novel type fiber, functional fillers of noise reduction and soft noise reduction composites was presented. Furthermore, the preparation method and the developing trend of soft noise-reducing textiles were summarized.
