Beschreibung
Zusammenfassung:	There is provided a sound insulating mat for sound insulation comprising at least a layer of combined natural fibers-binder web. The web comprises natural fibers in the range of 60 to 9wt.% of the web; and a synthetic binder in the range of 5 to 40 wt.% of the web. The web comprises a thickness and at least an upper surface and a lower surface opposite each other, and has a bulk density of 40 to 150 kg/m3.There is also provided a method for manufacturing the sound insulating mat and a noise control system comprising the sound insulating mat. L'invention concerne un tapis insonorisant pour isolation acoustique comprenant au moins un voile de liant de fibres naturelles combinées. Le voile comprend des fibres naturelles dans la plage de 60 à 9 % en poids du voile ; et un liant synthétique dans la plage de 5 à 40 % en poids du voile. Le voile comprend une épaisseur et au moins une surface supérieure et une surface inférieure opposées l'une à l'autre, et a une masse volumique apparente de 40 à 150 kg/m3.L'invention concerne également un procédé de fabrication du tapis insonore et un système de commande de bruit comprenant le tapis insonore.
