Assembly wall body having improved sound absorbing and screening performance and a assembly structure comprising the same
The present invention relates to an assembly wall having improved sound absorption/insulation performance and an assembly structure thereof. The assembly wall includes plate members separated from each other to face each other and each forming at least one layer; stud members alternately placed on different inner surfaces of the plate members and comprising a web formed with a plurality of first perforated holes having at least one diameter; an insulation member interposed in a space defined between the plate members and the stud members; and a sheet member adjoining an outer surface of the insulation member and being formed with a plurality of second perforated holes having at least one diameter. With this structure, the assembly wall has excellent sound absorption and insulation performance over various frequency bands including a low frequency band without increasing wall thickness.
1. An assembly wall having improved sound absorption/insulation performance, comprising:
plate members separated from each other to face each other and each forming at least one layer;
stud members alternately placed on different inner surfaces of the plate members and comprising a web formed with a plurality of first perforated holes having at least one diameter and configured for sound absorption;
an insulation member interposed in a space defined between the plate members and the stud members; and
a sheet member adjoining an outer surface of the insulation member, the sheet member interposed along with the insulation member in the space between the plate members and the stud members, and formed with a plurality of second perforated holes having at least one diameter configured for sound absorption,
wherein the sheet member, the plate members, and the stud members form hollow spaces of resonators configured for sound absorption in a low frequency band, and
wherein the diameters of the first and second perforated holes are selected for sound absorption of a frequency band.
2. The assembly wall of claim 1 , wherein the first perforated holes and the second perforated holes have different diameters depending on a major sound absorption frequency.
3. The assembly wall of claim 2 , wherein the first perforated holes and the second perforated holes have a diameter ranging from 0.1 mm to 5 mm.
4. The assembly wall of claim 1 , wherein the plate members comprise a material having sound insulation and fireproof functions.
5. The assembly wall of claim 4 , wherein the plate members comprise one material selected from among gypsum boards, magnesium oxide (MgO) boards, ceramic boards, cement boards, and lightweight concrete panels.
6. The assembly wall of claim 1 , wherein the insulation member comprises a material having thermal insulation and sound absorption functions.
7. The assembly wall of claim 6 , wherein the insulation member comprises one of rock wool, mineral wool, glass wool, ceramic fibers, polyethylene terephthalate (PET) nonwoven fibers, cellulose fibers, and various foaming materials.
8. An assembly structure having improved sound absorption/insulation performance, comprising:
an assembly wall, the assembly wall comprising:
plate members separated from each other to face each other and each forming at least one layer,
stud members alternately placed on different inner surfaces of the plate members and comprising a web formed with a plurality of first perforated holes having at least one diameter and configured for sound absorption,
an insulation member interposed in a space defined between the plate members and the stud members, and
a sheet member adjoining an outer surface of the insulation member, the sheet member interposed with the insulation member in the space between the plate members and the stud members, and formed with a plurality of second perforated holes having at least one diameter configured for sound absorption,
wherein the sheet member, the plate members, and the stud members form hollow spaces of resonators configured for sound absorption a low frequency band, and
wherein the diameters of the first and second perforated holes are sleeted for sound. absorption of a frequency band; and
a reinforced structure supporting the assembly wall.
