Abstract (en)
[origin: US6376396B1] A soundproofing material made of nonwoven materials containing thermoplastic fibers for the acoustic frequency range of 100 to 5000 Hz is characterized in that the nonwoven material is permanently compacted to a specific flow resistance of RS=800-1400 Ns/m3 in two stages by a mechanical compaction process and a subsequent pressure/heat treatment.
