Beschreibung
Zusammenfassung:	A sound absorption device for a moving body is provided with a resonance tube, an elastic modulus variable film, and an adjustment unit. One end part of a pipeline of the resonance pipe is configured to face the indoor space. In the elastic modulus variable film, one surface is disposed so as to face the indoor space, and the other surface is disposed so as to face the inner space of the other end of the resonance tube. The adjustment unit adjusts the elastic modulus of the elastic modulus variable film. 本发明提供一种移动体的吸声装置，其具备共鸣管、弹性模量可变膜及调整部。共鸣管的管路的一端部面向室内空间地配置。弹性模量可变膜中，一方的面面向室内空间地配置，另一方的面面向共鸣管的另一端部的内部空间地配置。调整部调整弹性模量可变膜的弹性模量。
