Abstract (en)
A soundproofing wall for isolating a first room on one side of the soundproofing wall from a sound source on the other side of the soundproofing wall, the soundproofing wall comprising a plate-type acoustic metamaterial with a baseplate and a plurality of masses arranged on the baseplate wherein at least one of the masses is strip-shaped.
