    摘要: An object is to provide a silencing system that can achieve both high ventilation performance and high soundproof performance, can silence a plurality of pieces of resonant sound, and has high general-purpose properties since the silencing system does not need to be designed according to a tubular member. In a silencing system where silencers are disposed on a tubular member, the silencers silence sound having a frequency of first resonance of the tubular member, each silencer includes a cavity portion and an opening portion, the opening portions are connected to a sound field space of the first resonance of the tubular member, a conversion mechanism for converting sound energy into thermal energy is disposed in each cavity portion or at a position where the conversion mechanism covers the opening portion, a ratio S1/Sd of the area S1 to the area Sd satisfies “0

    摘要: 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.

    摘要: A surface enhanced Raman spectrometry apparatus is constituted by: a transparent substrate; a metal member that causes surface enhanced Raman scattering to occur, formed on a surface of the transparent substrate; a pressing mechanism that presses a sample placed in contact with the metal member against the metal member; a measuring light irradiating optical system that irradiates a measuring light beam onto the sample through the transparent substrate; and a light detecting section that spectrally detects Raman scattered light, which is generated when the measuring light beam is irradiated onto the sample, through the transparent substrate.
