Abstract

Sound source localization (SSL) plays a crucial role in acoustic sensing, with applications ranging from environmental monitoring and biomedical diagnostics to industrial automation. However, achieving accurate and precise SSL in complex and dynamic acoustic environments remains a challenge. Recent advances in acoustic sensors and signal processing techniques have significantly improved SSL performance, accuracy, efficiency, and robustness in real-world conditions. This review presents these developments, emphasizing the role of SSL in bioacoustics for wildlife tracking, wind turbine noise assessment, speech enhancement, medical science, and industrial automation. Key challenges, such as localization in reverberant and remote acoustic environments, are discussed alongside emerging solutions, including bio-mimetic micro-electro-mechanical systems (MEMS) microphone and energy-efficient wake-up technologies. By analyzing current trends, challenges, and technological progress, this review provides insights into the future of SSL as a key component of modern intelligent sensing systems.

综述了声源定位技术的最新进展、挑战和应用

声源定位（SSL）在声传感中起着至关重要的作用，其应用范围从环境监测和生物医学诊断到工业自动化。然而，在复杂和动态的声学环境中实现精确的SSL仍然是一个挑战。声学传感器和信号处理技术的最新进展显著提高了SSL在现实条件下的性能、精度、效率和鲁棒性。本文综述了这些进展，强调了SSL在生物声学、野生动物跟踪、风力涡轮机噪声评估、语音增强、医学科学和工业自动化方面的作用。主要挑战，如在混响和远程声学环境中的定位，以及新兴的解决方案，包括仿生微机电系统（MEMS）麦克风和节能唤醒技术。通过分析当前的趋势、挑战和技术进步，本综述提供了SSL作为现代智能传感系统关键组成部分的未来见解。
