附加薄膜-质量块谐振器的Herschel-Quincke管及基于该结构的隔声帘的研究
Research on a Herschel-Quincke pipe with membrane-mass resonators attached and a sound insulation curtain based on the structure
摘要
Abstract
Acoustic metamaterials exhibit great potentials in insulation for sound and vibration,where membrane-based acoustic metamaterials are given high consideration for small masses and sound insulation ability at low frequencies.Here,a membrane-mass attached Herschel-Quincke pipe(MAHQP)is presented.Theoretical analysis,numerical simulations and experiments show that low-frequency and multiple-band sound insulation could be achieved through using the MAHQP due to the coupling between Herschel-Quincke pipe and the membrane-mass resonator.Additionally,a rectangular box is designed,in which the front and rear faces are created using membrane-mass resonators.Furthermore,a sound insulation curtain is designed on the basis of a two-dimensional array of the rectangular box.The sound insulation of the curtain is studied by simulations,which demonstrates that low-frequency,multiple-band sound insulation can be obtained in a free acoustic field.关键词
