The invention relates to an acoustic treatment panel comprising at least one acoustic resistive layer (22), a reflective layer (24) and at least one honeycomb structure (26) interposed between the acoustic resistive layer (22) and the reflective layer (24) and comprising:-an identical and cylindrical main tube (28) closed at one end by the acoustic resistive layer (22) and at the other end by the reflective layer (24); -intermediate regions (30) located between the main tubes (28), which are sealed from each other; -cutouts (42, 44) made at the level of one end of certain main tubes (28) in contact with the reflective layer (24) and/or secondary tubes positioned in the main tubes (28) and/or in the intermediate region (30), the cutouts (42, 44) and/or secondary tubes being configured to be able to produce acoustical units of different sizes from the same main tubes (28).
本发明涉及一种声学处理面板,包括至少一个声阻层(22)、反射层(24)以及至少一个蜂窝结构(26),蜂窝结构(26)插设于声阻层(22)和反射层(24)之间,并包括:‑相同且为圆筒形的主管(28),其在一端处由声阻层(22)封闭而在另一端处由反射层(24)封闭;‑位于主管(28)之间的中间区域(30),其彼此密封;‑在某些主管(28)与反射层(24)接触的一端的高度处实施的切口(42、44)和/或定位于主管(28)和/或中间区域(30)中的次级管,切口(42、44)和/或次级管被构造为能够由相同的主管(28)产生不同尺寸的声学单元。
