    • PROBLEM TO BE SOLVED: To provide a silencer capable of enhancing noise suppressing performance while keeping ventilation performance.
      SOLUTION: This silencer 1 is constituted by arranging a plurality of cell-shaped noise suppressors 2 attached with a sound absorbing material 4 on an inner wall of a cylindrical outer plate 3 in a midway of a duct while directing longitudinal directions thereof along a flow passage direction of the duct, and the plurality of cell-shaped noise suppressors 2 comprise ones having two kinds of different numerical apertures. A self-noise generated from the silencer 1 is reduced thereby while keeping the ventilation performance, and the noise suppressing performance is also increased thereby in a noise source.
