Abstract: By taking “sound” as a pointcut， White Noise， one of the remarkable works of contemporary American writer Don DeLillo， explores the relationship among soundscape， consumption and ethics. Through auditory imagery and sound description in this novel， DeLillo points out that the prosperity of commodity economy， progress of science and technology and over-development of media culture in the post-modern society have brought about the destruction of the living environment and the imbalance of spiritual ecology， which inevitably lead to people's deep fear of death. Meanwhile， DeLillo attempts to remind modern people that a harmonious multi-layered relationship between individuals， human and nature， human and society， and society and nature might be achieved by reshaping an awareness of ecological holism and a healthy social-ecological environment， in which a sustainable development can be fundamentally actualized.

Key words: Don DeLillo; White Noise; soundscape; consumption alienation; environmental ethics
