The invention relates to a noise reduction apron board manufacturing method, a noise reduction apron board and a vehicle, the noise reduction apron board comprises at least one noise reduction area, each noise reduction area comprises a plurality of noise reduction units, and the method comprises the steps that the frequency range of noise is determined, and a plurality of frequency band intervals are divided based on the frequency range, wherein the noise reduction unit corresponds to the frequency band interval; confirming structure information of the noise reduction unit according to the corresponding frequency band interval, and setting a corresponding structure of the noise reduction unit according to the structure information; and the corresponding structures of the noise reduction units in each noise reduction area are coupled to obtain the noise reduction apron board. According to the apron board, targeted sound insulation and noise reduction can be conducted on noise of different frequency bands, broadband noise can be effectively reduced, and the sound insulation and noise reduction effect of the apron board is improved.

    本申请涉及一种降噪裙板的制造方法、降噪裙板和车辆,所述降噪裙板包括至少一个降噪区域,每个所述降噪区域包括多个降噪单元,所述方法包括:确认噪声的频率范围,并基于所述频率范围划分多个频段区间,其中所述降噪单元与所述频段区间对应;根据对应的所述频段区间确认所述降噪单元的结构信息,并根据所述结构信息设置所述降噪单元的对应结构;将每个所述降噪区域内的所述降噪单元的所述对应结构进行耦合,以得到所述降噪裙板。本申请对于不同频段的噪音可以进行针对性的隔音降噪,能够有效降低宽频的噪音,提升裙板的隔音降噪效果。
