Abstract
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. 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.
