在这篇文章中，不同的技术定位声源的描述和这些技术的优点/缺点进行了讨论。一些源定位技术仅限于各向同性结构，而其他方法也可以应用于各向异性结构。一些技术需要各向异性体中依赖于方向的速度分布的精确知识，而其他技术不需要该知识。一些方法需要声波到达接收器的时间的精确值，而其他技术可以在没有该信息的情况下起作用。已发表的介绍各种技术的论文强调了所介绍技术的优点，而忽略了新技术的局限性和弱点。文献中缺乏的是对现有技术的全面回顾和比较;本文试图做到这一点。在回顾了各种技术之后，本文总结了哪种源定位技术对于什么类型的结构应该是最有效的以及当前的研究需求是什么。(C)2013年爱思唯尔B。V.保留所有权利。
In this article different techniques for localizing acoustic sources are described and the advantages/disadvantages of these techniques are discussed. Some source localization techniques are restricted to isotropic structures while other methods can be applied to anisotropic structures as well. Some techniques require precise knowledge of the direction dependent velocity profiles in the anisotropic body while other techniques do not require that knowledge. Some methods require accurate values of the time of arrival of the acoustic waves at the receivers while other techniques can function without that information. Published papers introducing various techniques emphasize the advantages of the introduced techniques while ignoring and often not mentioning the limitations and weaknesses of the new techniques. What is lacking in the literature is a comprehensive review and comparison of the available techniques; this article attempts to do that. After reviewing various techniques the paper concludes which source localization technique should be most effective for what type of structure and what the current research needs are.
