Chorus waves are naturally occurring whistler waves and are nearly monochromatic and discrete in time. Hiss waves are broadband and incoherent. This proposal addresses the relationship between these two types of waves and in particular will evaluate the idea that chorus waves evolve into hiss as they propagate. The proposal will use ground based instruments, laboratory experiments and numerical ray tracing. This research is important for magnetospheric physics because both types of wave emissions are thought to control the population of energetic electrons. This is a CAREER proposal and as such it has an extensive education and outreach element. It includes training of K-12 students as well as undergraduate and graduate students. It will involve the use of Capstone Senior Design projects to develop applications for smart phones. These waves are in the audio frequency range and can be received and recorded by using smart phone technology.

合唱波是自然产生的哨声波，在时间上几乎是单色的和离散的。嘶嘶波是宽带的，不连贯的。这项建议解决了这两种波之间的关系，特别是将评估合唱波在传播时演变为嘶嘶声的观点。该提案将使用地面仪器、实验室实验和数值射线追踪。这项研究对磁层物理学很重要，因为这两种类型的波发射都被认为控制了高能电子的数量。这是一份职业提案，因此它包含了广泛的教育和外展内容。它包括对K-12学生以及本科生和研究生的培训。它将涉及使用Capstone高级设计项目来开发智能手机应用程序。这些波在音频范围内，可以使用智能手机技术进行接收和记录。
