The identification of sound sources, their location and strength is an important and practically relevant research area in applied acoustics. Sound, its strength and distribution, is important for individuals living in an urban environment, having basic influence on the overall condition and motivation of human beings. Further, sound is commonly used as a tool for non-destructive testing and the evaluation of inaccessible regions of space or bodies. The identification of sound sources has thus been an important research area which has caught the attention of both engineers and mathematicians.The proposed fellowship intends to relocate one of the leading researchers from the field of mathematical theory and simulation of inverse problems into an engineering environment in acoustics to learn to employ state-of-the-art measurement technology and to apply new mathematical algorithms to important real world problems. The goal is to make practical progress on the sound source identification problem via high-level mathematics and to significantly contribute to the interaction of the applied and theoretical disciplines of engineering and mathematics.

声源、声源位置和声源强度的识别是应用声学中一个重要的和实际相关的研究领域。声音的强度和分布对于生活在城市环境中的个体来说是重要的，对人类的整体状况和动机有着基本的影响。此外，声音通常用作无损测试和评估空间或身体难以到达区域的工具。因此，声源的识别一直是一个重要的研究领域，引起了工程师和数学家的注意，拟议的研究金打算将一位主要研究人员从数学理论和反问题模拟领域重新安置到声学工程环境中，学习使用最先进的测量技术，并将新的数学算法应用于重要的真实的世界问题。目标是通过高级数学在声源识别问题上取得实际进展，并为工程和数学的应用和理论学科的相互作用做出重大贡献。
