Embodiment Construction
[0034] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. Apparently, the described embodiments are some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0035]For the ventilation and sound insulation window unit with double structure, when it is regarded as a whole system, its surface response can be divided into monopole response and dipole response, and its coupling results can form the sound insulation effect. The present invention proposes a solution for homogenizing the ventilation barrier, which combines eigenmode analysis, that is, the transmission or reflection behavior of the sound barrier can be described by its eigenmode. The results show that the amplitude of transmitted ...
