Aircraft door arrangement with sound reduced hollow space which can be covered by an aircraft door

An aircraft comprising:

• an aircraft fuselage;
• and
• an aircraft door arrangement comprising:
• an aircraft door;
• at least one door seal arranged at an inner surface of the aircraft door and circumferentially extending in an edge region of the aircraft door;
• and
• a door opening closable by the aircraft door which door opening has an opening edge adjoining thereto and extending into an interior of the aircraft fuselage, at which opening edge a seal seat is arranged which can be brought into a flush contact with the door seal;
• wherein a hollow space is formed by the door seal, the seal seat and the opening edge, which hollow space is at least partially covered by the edge region of the aircraft door;
• wherein a gap is connected with the hollow space when the aircraft door is closed, which gap is located between the aircraft door and the door opening;
• and
• wherein a sound reducing profile is arranged at the opening edge in the hollow space, which sound reducing profile comprises at least one planar surface section which is oriented oblique with respect to a surface of the aircraft door which surface is adjacent to the gap, wherein the planar surface section at least partially follows the course of the gap.
