A sound absorption and insulation module for a vehicle includes a perforated panel that defines a plurality of holes, a sound absorption material, and a sound insulation material. The perforated panel, the sound absorption material, and the sound insulation material are sequentially coupled. A diameter of the holes, a number of the holes, and a distance between the holes are determined based on noise frequency bands, thereby effectively responding to noises in various frequency bands generated from one or more portions of a specific component of the vehicle.
