본 발명은 차량용 흡차음모듈에 관한 것으로, 다수의 구멍(11)이 형성된 타공패널부(10)와 흡음재(20) 및 차음재(30)가 순차적으로 결합되어 일체화를 이루고, 타공패널부(10)의 구멍(11)은 소음의 주파수 영역대가 다른 부위별로 직경 크기(D1)와 개수 및 구멍간 거리(L1)가 상이하게 형성되어, 특정 부품에서 부위별로 상이하게 요구되는 다양한 주파수 영역대의 소음에 모두 효과적으로 대응이 가능하도록 된 것이다.

    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.
