[0010] Compared with the prior art, the present application can obtain the following technical effects:

[0011] The sound-absorbing layer and the sound-insulating layer of the present utility model are made of fiber cotton and rubber. Sound-absorbing holes and sound-absorbing cavities are provided on the sound-absorbing layer, which can absorb sound and attenuate the sound. Grooves are provided on the sound-insulating layer to reflect the attenuated sound to achieve a good sound field effect. The second sound-insulating layer can block the sound from propagating to the outside, so that the building can have better sound quality and no external noise is generated.
