SILENCING STRUCTURE AND SILENCING SYSTEM
To provide a silencing structure and a silencing system having a high sound absorbance in a low frequency region. A silencing structure that is installed in a tubular member, the silencing structure includes a cavity portion, an opening portion through which the cavity portion communicates with the tubular member, and a closing portion that closes the cavity portion at a position facing the opening portion, in which a cross-sectional area of the cavity portion on a side of the opening portion is larger than a cross-sectional area of the cavity portion on a side of the closing portion.
