Abstract
Provided is a silencing tubular structure body that has high strength and can be disposed in a narrow space. A tubular member including a tubular portion having a tubular shape, and a frame portion having at least a part formed integrally with an inner peripheral surface side of the tubular portion; and a lid member that is exchangeably disposed on an opening surface of the frame portion of the tubular member are included, in which the frame portion and the lid member form a resonant silencing structure.

A silencing tubular structure body comprising:
- a tubular member including a tubular portion having a tubular shape, and a frame portion having at least a part formed integrally with an inner peripheral surface side of the tubular portion;
- and
- a lid member that is exchangeably disposed on an opening surface of the frame portion of the tubular member,
- wherein the frame portion and the lid member form a resonant silencing structure,
- the lid member is a plate-like member that is smaller than the opening surface of the frame portion and covers a part of the opening surface,
- the silencing structure is a resonant structure having a hollow portion surrounded by the frame portion and the lid member, and an opening portion of the opening surface that is not covered by the lid member, and
- the frequency band of the sound silencing structure can be changed by replacing the lid member.
