摘　　要：在基体中分散着无数气泡的泡沫铝是一种用途广泛的功能材料。文中概述了泡沫铝的吸声机理、吸声结构，以及气孔率、压缩率、板厚、空气层厚度对泡沫铝吸声性能的影响，给出了泡沫铝用于噪声控制的典型实例。The foamed aluminum is a functional material with wide application. The mechanism,structure of acoustic absorption as well as the influences of porosity rate,compression rate,thickness of foamed aluminum and thickness of air layer on the acoustic absorption are briefly reviewed,and some examples of foamed aluminum application on noise control are offered.
