Abstract

Flow resistive textiles are becoming more popular almost in all aspect of acoustic applications where sound absorption is a primary noise reduction countermeasure: industrial acoustics (reduced sound propagation in work places), architectural acoustics (shaping interior acoustic properties) and the automotive acoustics (bonnet liners, firewall insulators). While the automotive applications are not very demanding in terms of flammability, the industrial and architectural applications must comply with severe flammability restrictions. As it is today only non-flammable porous materials like mineral fibre, ceramic fibre or melamine foam would comply with stringent fire specifications. We will show that the wise choice of the flow resistive textile enable to widen the range of materials complying with actual standards. The traditionally good sound absorbers like polyester fibre or foam could then become available to architects again.
