  • the soundproofing element is arranged only on the underside of the second profile body of the profile element, so that the optimized soundproofing effect can be realized without the soundproofing element being visible to the user of the cabinet furniture.
  • At least one opening is introduced in at least one profile body.
  • This has the advantage that the sound can penetrate through the opening in the profile body of the profile element in the cabinet furniture and can spread there.
  • the sound is at least partially absorbed in the cupboard furniture.
  • the reflected back from the cabinet furniture sound is now at least partially reflected back from the profile elements of the front blinds in the cabinet furniture, so that only a very small proportion of the sound is reflected back into the room.
