Description
この構成によると、送風経路を小区画化することができるため、送風手段の送風音が拡散しにくくなり、室内に放射される騒音が確実に低減され、十分な消音効果を得ることが可能となる。更に望ましくは、前記区画の幅は85mm以下である。この構成によると、前記区画の幅が2,000Hzの音波の約1/2波長以下となり、前記区画を通過する音波を略平面波、即ち前記区画内は一次元の音場とみなすことができ、特に2,000Hz以下のアクティブ消音が得意とする低周波数域において十分な消音効果を得ることができる。 According to this configuration, since the blowing path can be subdivided, the blowing sound of the blowing means is difficult to diffuse, the noise radiated into the room is reliably reduced, and a sufficient silencing effect can be obtained. Become. More preferably, the width of the section is 85 mm or less. According to this configuration, the width of the section is about ½ wavelength or less of a sound wave of 2,000 Hz, and the sound wave passing through the section can be regarded as a substantially plane wave, that is, the inside of the section as a one-dimensional sound field, In particular, a sufficient silencing effect can be obtained in a low frequency range where active silencing at 2,000 Hz or less is good.
