    Abstract: Two or more soundproof cells arranged in a two-dimensional manner are provided. At least one of the soundproof cells is a first soundproof cell configured to include a first frame having a first through-hole. At least one of the other soundproof cells is a second soundproof cell including a second frame having a second through-hole and a film fixed to the second frame. A first shielding peak frequency, which is determined by the first through-hole of the first soundproof cell and at which a transmission loss is maximized, is present on a lower frequency side than a first natural vibration frequency of the film of the second soundproof cell, and sound in a predetermined frequency band centered on the first shielding peak frequency is selectively insulated.

    Abstract: An object is to provide a silencing system that includes a silencer disposed in a ventilation sleeve, can suppress the generation of negative pressure in the interior, and can prevent a door or the like of an interior entrance from being difficult to open. The silencing system includes one or more silencers that are disposed in a ventilation sleeve provided to penetrate a wall separating two spaces, and “αA>10C−(0.1/P)×TL” is satisfied in a case where a gap equivalent area of the ventilation sleeve in which the silencer is installed is denoted by αA and a normalized sound transmission loss in an octave band in which a first resonant frequency of the ventilation sleeve is present is denoted by TL.
    C denotes a constant determined by a measurement system in a case where there is no silencer and P denotes a transmission efficiency coefficient.
