摘要： An air intake apparatus has an air intake port opening outside, and an air intake path communicating the air intake port with a combustion chamber of an engine. For suppressing noise getting out from the air intake port, with respect to walls partitioning the air intake path, an opening is provided at a part of said walls corresponding to an antinode region of resonance mode of standing wave in a full length of the intake path, or at a part of noise pressure level being high in the intake path. The opening is closed with a permeable member and a noise insulating wall is disposed outside the permeable member for suppressing emission of transmitting noise passing through the permeable member. Alternatively, a vibration control member for suppressing face-vibration of the permeable member and reducing radiant noise from the permeable member is provided instead of the noise insulating wall.

摘要： An air intake sound control structure comprises a sound guiding pipe, a sound producing body, and a silencing means. The sound guiding pipe is branched off from a branch portion formed on a part of an air intake flow passage of an automobile, communicating with the air intake flow passage. The sound producing body is held by the sound guiding pipe at the position spaced apart from the branch portion, thereby sealing the sound guiding pipe, and producing a sound at a frequency which corresponds to its own natural vibration frequency by its vibration. The silencing means is disposed on the side of the branch portion of the sound guiding pipe and canceling a sound at a target frequency for suppression out of the air intake sound. The sound generated by the vibration of the sound producing body is transmitted into a vehicle interior.
