Underwater signal processing and signal detection schemes require well-characterized spatial and temporal ambient noise field properties to operate effectively in tasks such as detecting ships, submarines, marine mammals, and other underwater sound sources. Additionally, a detailed understanding of the noise field in the ocean has led to the development of passive methods for querying the physical properties of the ocean, seabed and sub-bottom as well as investigating the physics and statistics of noise source mechanisms such as air-sea interaction, surface wave breaking, rainfall, geophysical processes, and bedload sediment transport. More recently, underwater noise has been proposed as a monitoring tool to study the ecological health of the oceans.

水下信号处理和信号检测方案需要良好的空间和时间环境噪声场特性，以便在探测船舶、潜艇、海洋哺乳动物和其他水下声源等任务中有效地工作。此外，对海洋中噪声场的详细了解导致开发了被动方法，用于查询海洋、海底和次海底的物理性质，并调查噪声源机制的物理和统计数据，例如海气相互作用、面波破裂、降雨、地球物理过程和推移质泥沙输送。最近，有人提议将水下噪音作为研究海洋生态健康的一种监测工具。
