Atmospheric acoustics is the study of propagation of sound waves in the atmosphere . listed in it is the study of infra - sonics , which focuses on inaudible , low - frequency sounds 研究声音在大气中传播特性的科学称为大气声学,当中的次声学便是专注于人耳无法听到的低频声音。
Know the various hazardous weather systems by their infra - sonic properties will help understand their behaviour and make better forecast . this has recently become an important topic in the study of infra - sonics 认识并利用次声方法来预测各类危险天气的活动规律,成为近代次声学研究的重要课题。
