The invention provides a silencing air inlet system for a vehicle, and belongs to the field of vehicles. The silencing air inlet system comprises a silencing structure, an upper air inlet channel assembly and a lower air inlet channel assembly, wherein the upper air inlet channel assembly and the lower air inlet channel assembly are connected, the silencing structure is arranged at the connectingposition of the upper air inlet channel assembly and the lower air inlet channel assembly, the silencing structure comprises a resonant cavity, at least one position-adjustable baffle is arranged in the resonant cavity, the baffles are used for dividing the resonant cavity into a plurality of volume-adjustable cavities, each cavity communicates with the lower air inlet channel assembly through a connecting pipe, and the silencing structure is configured to adjust the silencing frequency thereof by adjusting the length of each connecting pipe and/or the position of each baffle. The silencing air inlet system is wide in application range, good in platformization, high in universality and beneficial to cost reduction, and a whole vehicle space can be fully utilized to design the silencing structure.
