Opis

Acoustics, initiated by considering the mathematical aspects of speech, topics related to speech and musical instruments, is widely developed today in various fields, including electroacoustics, architectural acoustics, ultrasound, hydroacoustic and audio information processing, as well as physical acoustics, which study the fundamental theory of sound wave generation and propagation in solid, liquid, gas, etc. Localization is the most popular field of acoustic research. Several studies to determine the position have attracted much attention from many engineers.In particular, many positioning systems have been developed with increasing research to determine the position of static sound sources using sound and shock waves.These positioning systems are used as an indispensable tool for accurate and rapid determination of the position of the source.The sound wave used in positioning propagates from the source to the sound velocity, and the shock wave occurs only when the aircraft moves above the sound velocity. Although studies have been carried out in part to determine the position of these sound waves and shock waves, a comprehensive review of this has not yet been published.
