摘要： A separation structure between two adjacent cabins (C1, C2), comprising two partitions (W1, W2) facing opposite one to the other, separated from each other by an air gap (30). Each partition wall consists of at least one partition panel (2, 20) comprising: at least a first metal sheet (3) made of an iron alloy and a thickness between 0.5 and 0.9 mm; at least one layer of soundproofing material (4) associated to the metal sheet. The soundproofing material comprises mineral wool having a fibred structure with a content of non-fibred material of less than 1% by weight, an apparent density between 80 and 120 kg/m3 and a resistivity to airflow between 50 and 300 kPa s/mi. The layer of soundproofing material has a thickness between 12 and 28 mm.. The structure has an apparent sound reduction index R'w between the two adjacent cabins of not less than 43 dB ±1 dB. A panel of such a structure, a passenger ship with such a structure and the use of said soundproofing material are also described.
