    • PROBLEM TO BE SOLVED: To effectively prevent a flowing water sound in a bent portion of piping such as an elbow, and especially to prevent a low frequency band.SOLUTION: A rubber sheet 2 of weight ≥2 kg/m, and JIS hardness 60 to 80 (JIS A 6253) are tightly wound on the outer surface of the piping bent portion 1 such as the elbow, and further on the surface, a soundproofing body consisting of a sound absorber and a sound blocking body are attached. Then the flowing water sound is measured, and it is found that the flowing water sound of the low frequency band around 500 Hz is prevented from spreading outside a conduit. The kind of the rubber of the rubber sheet is not especially limited, and any rubber having a certain amount of weight and also having a flexibility enough to be tightly fixed to a pipe may be used. The rubber sheet may be tightly attached to a piping member by using an adhesive, and two or more rubber sheets may also be used.
    • 要解决的问题:为了有效地防止诸如弯头的管道的弯曲部分中的流水声音,并且特别是防止低频带。

      解决方案:将重量≥2kg/ m 2 和JIS硬度60至80(JIS A 6253)的橡胶片2紧密地缠绕在 配管弯曲部1如肘部,并且还在表面上安装有由吸声器和隔音体组成的隔音体。 然后测量流动的水声,并且发现在500Hz附近的低频带的流水声音被阻止扩散到管道外部。 橡胶片的橡胶的种类没有特别限制,可以使用任何具有一定量的重量并且具有足够紧密地固定在管上的柔性的橡胶。 橡胶片可以通过使用粘合剂紧密地附接到管道构件,并且也可以使用两个或更多个橡胶片。 版权所有(C)2013,JPO&INPIT
