  • Such a soundproofing component 1, due to the high density of the additives further has a high mass, and thus also a high sound insulation capacity.
  • a soundproofing component 1 is preferably a component which provides or permits protection against sound. Protection against sound in this context means a reduction of the sound pressure by the soundproofing component 1, which is arranged between a sound source and a sound sink. This preferably includes any type or cause of the reduction of this sound pressure level by the soundproofing component 1, for example due to sound attenuation, sound insulation, transmission losses within the soundproofing component 1 and / or reflection losses when the sound waves strike the first surface 3.
